The costs of disposing these wastes are high. In the same time, the demand of industry for raw materials is increasing rapidly and certain raw materials become more and more expensive as their availability becomes limited. Waste recycling and waste prevention are possible solutions for these problems. The implementation of these approaches requires new chemical processes. Due to the variability of composition of wastes as raw materials, the development of these technologies is a large challenge for chemical engineering, too. The sustainability of our society and the environment, however, depends largely on the success of these R&D activities. The development of greener processes are investment into the future. In order to achieve these goals, the University of Pannonia together with the College of Dunaujváros applied for a TÁMOP-4.2.2.A-11/1/KONV grant called for the funding of implementation of basic research projects with international cooperation in the framework of the Social Renewal Operational Program (TÁMOP) of the New Széchenyi Plan. The goal of the project entitled “Materials from characterization to industrial application – renewable feedstock and waste recycling” was to start an R&D activity in order to establish new tools and procedures that support the integrated development of products and technologies. The guiding principle and concept of the project is the development of green processes and technologies considering simultaneously the interests of industries of strategic importance and the different aspects of sustainable development. The research activities taking place in the project cover different levels of time and space from molecular modeling to design of technological procedures. The control and supervision of these activities require the application of an integrated multilevel approach that manages the whole project effectively.

BÉLAFI-BAKÓ , E. MOLNÁR, Z. CSANÁDI, N. NEMESTÓTHY University of Pannonia, Research Institute on Bioengineering, Membrane Technology and Energetics, 10 Egyetem Str., 8200 Veszprém, HUNGARY E-mail: bako@almos.uni-pannon.hu Electrodialysis (ED) is an electromembrane separation process suitable for recovery of organic acids. In this work galacturonic acid (GA) obtained by enzymatic hydrolysis of pectins from various sources was separated by a laboratory scale, two-step ED stack and a scaled-up, complex ED system. The experimental results from the two systems were compared. Keywords: electrodialysis, pectin, galacturonic acid Introduction Galacturonic acid is the monomer of pectin, a polysaccharide [1] often occurred in agro-wastes, like sugar beet pulp, apple pomace, press cakes of fruits... etc. Pectin can be hydrolyzed by enzymes and the process results a galacturonate (Gat) solution. Since it is an acidic (charged) compound, its recovery and separation can be carried out by electrodialysis (ED). Electrodialysis is an electro membrane process, where charged components move in the direction of the oppositely charged electrode under electrical potential difference [2, 3]. ED has already been applied to separate various organic acids like citric acid, lactic acid, acetic acid, propionic adic, gluconic acid, maleic acid [4–8]. In case of pectin hydrolysates ED can be used for recovery and desalination of galacturonate ions (the counter ion is usually Na). A laboratory scale, two step ED stack and a Fumatech FT-ED-4-100-10 scaled-up complex module were applied in our laboratory to recover GA ([9 ,10]. In this work the stacks are compared from the aspects of yield, operation parameters, energy requirement and average current efficiency. Material and methods Galacturonic acid (GA) applied in the model solutions was purchased from Sigma-Aldrich, while sodium sulphate from Spectrum (Hungary). Cation- (Fumasep FKB), anion-selective (Fumasep FAB) and bipolar (BP) membranes were purchased from Fumatech. Hydrolysis of pectin solutions from sugar beet pulp and citrus was carried out by pectinase enzymes (Pectinex 100L enzyme preparation) in a shaking incubator. The process was followed by acid titration (0.5 M NaOH). The laboratory scale ED set up consisted of two stacks (one conventional and the other contains bipolar membrane) was constructed in our workshop. The first stack was an symmetric ED cell (described in [9]), with 0.0225 m2 membrane surface area. Here the galacturonate ions from the hydrolysate moved toward the anode and passed through the anion selective membrane, while sodium ions are transported in the other way. Thus a concentrate stream containing mainly Na-galacturonate was formed. Then its desalination was carried out in the second ED cell, where 2 cation selective and a bipolar membrane were built in (Figure 1) altogether with 0.0135 m2 membrane surface area. Separation of sodium and galacturonate ions was possible: galacturonate anions remained in the feed solution forming an acid solution, while Na ions passed through the cation selective membrane into the alkali solution forming NaOH. Figure 1: Set-up of the second laboratory scale ED module 66 The scaled-up complex module containing cation, anion selective and bipolar membranes was described in [10], its membrane surface area was 0.31 m2. Both ED stacks were operated by recirculation, using Na2SO4 solution (electrode solution). The experiments were followed by measuring the concentration of GA (DNS test [11]) in various streams, conductivity, pH, electric current and voltage, the data were collected by a data acquisition device (National Instruments USB- 6008/6009) and recorded by the program LabVIEW. The important stack and operation parameters for the laboratory scale stacks and the scaled-up complex ED module were summarized in Tables 1 and 2, respectively.

The experimental results are compared in Table 3. From the table it can be seen, that higher initial concentration feed was applied in case of the two-step laboratory module, since in the second step we had to use the result of the first step: the Na-galacturonate solution (recovered from the hydrolysate). It was desalinated in the BP module. In the scaled-up complex system the separation process (recovery and desalination) was achieved in one single step. Though the energy consumptions were much higher in the scaled-up system and the current efficiencies were lower (than in the laboratory scale stack), but larger amount of product solutions (pure galacturonic acid) were manufactured. If the product acid obtained were related to the energy consumption, we found that – in case of ED separation of sugar beet pectin hydrolysate – 1 Wh energy resulted in 0.09 g and 0.13 g GA production by the two-step, laboratory and the scaled-up, complex system, respectively. The scaled-up system worked with higher effectiveness, moreover it should be taken into account that its operation can be further optimised, and the energy consumption might be reduced even more. 67 Table 3: Comparison of the two ED systems Two-step laboratory ED system Hydrolysate asymmetric ED BP module Scaled-up complex ED system from sugar beet pulp pectin feed volume feed conc. yield current eff. energy final result 100 ml 36.5g/l 63% 56% 9.2 Wh 150 ml 15.4 g/l Na- Gat solution 100 ml 15.4 g/l desalination – 4.6 Wh 100 ml 12.1 g/l desalinated GA solution 400 ml 15 g/l 65% 41% 31 Wh 400 ml 9.8 g/l desalinated GA solution from citrus pectin feed volume feed conc. yield current eff. energy final results 100 ml 48.9 g/l 78% 63% 8.9 Wh 150 ml 25.4 g/l Na- Gat solution no data 400 ml 39 g/l 86% 54% 39 Wh 400 ml 33.5 g/l desalinated GA solution The yield, current effectiveness values are better for citrus pectin hydrolysate than for sugar beet pulp pectin hydrolysate, which may be explained by the higher purity of the citrus pectin preparation. As a summary, we concluded that electrodialysis is a suitable method for recovery, desalination and purification of galacturonic acid from hydrolysates of various pectins. The complex module was able to separate the product in one step and it seems that the scaled-up system worked more efficiently: higher yield was achieved by less energy consumption. Therefore the complex ED system is suggested to apply for further experiments, aiming to study the possibilities of industrial applications.

VARGA1 , B. TÓTH1, P. GERGÓ1, L. BARTHA1 1University of Pannonia, Institutional Department of MOL Hydrocarbon and Coal Processing, 10 Egyetem Str., 8200 Veszprém, HUNGARY E-mail: vcsilla@almos.uni-pannon.hu In our experimental work application of carbon nanotubes in rubbers have been investigated. The effects of the type of the rubber matrix, the concentration of the carbon nanotubes and the effects of a coupling agent on the mechanical properties of the composites have been studied. The strength of the rubber matrix had great influence on the strengthening behaviour of the carbon nanotubes. By application of surface treated carbon nanotubes the strength of the composites made from a rubber matrix having the tensile strength under 10 MPa could be improved by 35%. However, the composites from the rubber with higher tensile strength contained treated carbon nanotubes afforded balanced performance against fatigue stresses probably due to the effect of the coupling agent and the homogenous distribution of the carbon nanotubes. Introduction Rubbers reinforced with carbon black (CB) are used for numerous industrial applications, such as vibration- resistant structures, electromagnetic interface (EMI) shielding materials, antistatic devices, etc. [1–4]. CB improves the mechanical properties (modulus and strength) of the rubber due to the interactions among the fillers and the fillers and the other components of the rubber. The CB particles were proven to form aggregates because of the strong bonding effects to each other. A part of the rubber is encapsulated in those aggregates because of the branched structures of the latter one and is shielded from macroscopic deformations [1]. Small domain size is required for effective reinforcement. On the one hand only branched structures small enough (< 50 nm) can be trapped and thereby achieved a strongly bonded system, and on the other hand only the adequately small domains have high surface activity [1, 2]. In the last two decades researches focused on to substitute CB with another fillers (eg. caolin, sepiolite, SiO2, zinc-disorbate, titania) also having reinforcing effects [4–6] and also on to reduce the particle size of the CB to improve their dispersion in the rubber matrix [2]. In the former step modification of the surface of the fillers had to be also solved because they are incompatible with the most organic matrices, therefore, coupling agents were being used [5, 7]. The fillers for substitution of CB like SiO2 have been spread in the recent years especially due to the higher demand for non-black applications [7–11]. Several solutions have been developed in the CB/rubber research area: as two step grinding technology, application of dispersants or coupling agents, pre-treatment of the carbon surface or chemical modification of the elastomer chains, moreover distribution of the CB in a latex solution instead of solid mixing [2]. Not much significant improvements were achieved by the first three solutions. In case of the latter one the modification of the CB surface represented the largest difficulty in order to disperse them homogeneously in the water solution of latex [4, 12]. Application of CB has been still significant because besides it can increase the strength of the vulcanized rubber; it also has a positive effect on the optical and electrical properties, and reduces production cost [3]. Application of carbon nanotubes (CNT) may represent a breakthrough in rubber matrices either but only small quantities have been introduced because of their relatively high price. Furthermore, by dispersion of the CNT arisen the same problems like the CB due to the high surface charge [13,114]. A lot of papers were published about CNT/epoxy and CNT/thermoplastic composites but only a very few about CNT/elastomers [4, 8, 15–18]. The most exciting challenge in the area of CNT containing composites was to solve the proportional dispersion of the CNT because absence of a well-homogenized morphology the distinguished mechanical improvements of the reinforcement can not be achieved in elastomers either. E.g. Das and co-workers [19] used untreated and modified multi-walled carbon nanotubes (MWCNT) in a blend of styrene-butadiene rubber (SBR) and butadiene rubber (BR) with 50/50 ratio. Hydroxyl-groups were enacted to the surface of the modified MWCNT (Nanocyl®- 3153), and bis(triethoxy-silylpropyl)tetrasulfone was applied as the coupling agent for bonding to the rubber. Composites were manufactured by a two-roller mill and a stabilized non-ionic surfactant/ethanol solution was 70 used for MWCNT-treating. The coupling agent was applied in 2.5% related to the mass of the rubber. Strength of composites containing 5% MWCNT could be enhanced from 1MPa to 4.5 MPa. The new process with the ethanol solution was more effective then other traditional methods in the given concentration range. Similar properties were obtained by MWCNTs having hydroxyl-groups. Application of a silane type coupling agent did not significantly affect the mechanical properties. Our research has been directed to the application of MWCNT in rubbers. The MWCNT has the same favourable effect in the point of view of the mechanical properties [20–22] as CB, and moreover by introduction of a proper coupling agent strong interaction can be established between the MWCNTs and the rubber. As MWCNTs have excellent mechanical properties they should have better strengthening effect than CB has. If mechanical properties of rubber composites can be improved to a large extent enough then the cost reduction can become less important. For the surface treatment of MWCNT an olefin- maleic-anhydride copolymer based coupling agent has been applied [24]. Not only the possible effects of the coupling agent but also effects of the mechanical properties of the initial rubber matrix as raw material have also been investigated in MWCNT/rubber composites. 2. Experimental 2.1. Materials Multi-walled carbon nanotubes (MWCNT) were produced at 700°C by chemical vapor deposition (CVD) process over Fe-Co bimetallic catalyst at the Institutional Department of Chemical Engineering (Institute of Chemical and Process Engineering, University of Pannonia). Purity of MWCNT was higher than 90 wt%, the diameter was between 10 nm and 20 nm, the average length was above 30 μm. Natural rubber (NR) and styrene-butadiene rubber (SBR) based (R-I and R- II) and nitrile-butadiene rubber (NBR) (ACN content: 45%, Mooney viscosity, 100°C: 60) based blends (R- III) were used as matrix material.

Preparation of composites Compounds were prepared by a milling process. A two- roller mill was applied also for mixing the carbon nanotubes into the basic mixture of rubber. Sheets of the mixtures were compression moulded at 180°C for 5 minutes vulcanization time. Dog-bone samples for mechanical testing were cut from the sheets. Compositions of the samples were given in Table 1. Table 1: Composition of the different MWCNT/rubber composites sample rubber matrix type MWCNT content, wt% coupling agent, wt% C-1 R-I 0 - C-2 R-I 1.0 - C-3 R-I 1.0 0.2 C-4 R-II 0 - C-5 R-II 1.0 - C-6 R-II 1.0 0.2 C-7 R-III 0 - C-8 R-III 1.0 - C-9 R-III 1.0 0.2 C-10 R-III 1.5 - C-11 R-III 2.4 - C-12 R-III 2.4 0.5 Effects of the coupling agent were also studied by application with an experimental treating method developed for surface treating of MWCNTs for PP [24]. Surface of MWCNT was covered by the coupling agent from the hydrocarbon solution of the additive with stirring the mixture for 1 hour at 60°C then the solvent was distilled out. Treated MWCNTs were then dried at 110°C for 2 hours and were mixed into the basic mixture of rubber by a two-roller mill. R-I and R-II matrices were NR and SBR based blends with lower and medium mechanical strength, R- III matrix was an NBR based one with high mechanical strength. Thus effects of the type of the rubber were also studied on the properties of the composites. MWCNTs were applied in untreated and in treated form in order to investigate the influence of the coupling agent either. 2.3. Measurement of tensile properties To determine the tensile and fatigue tensile properties (mainly stress, modulus and extension) (MSZ EN ISO 527-1-4:1999) an INSTRON 3345 universal tensile 71 testing machine was used. The temperature in the laboratory was 23°C and the relative humidity was 50% during the mechanical tests which were carried out at 90 mm/min crosshead-speed both in case of tensile and fatigue tensile tests. Structural information about the developed coupling agent was obtained by infrared technique with a TENSOR 27 type FTIR1, illumination: SiC Globar light, detector: RT-DLaTGS type) in the 400-4000 cm-1 wavenumber range. Scanning Electron Microscopy (SEM) was used to study the structure of fractured faces of the specimens and to follow the possible interaction between the reinforcements and the matrices. The applied apparatus was a Phillips XL30 ESEM instrument. 3. Results and discussion Discussion of the results was divided into three parts. On the first hand effects of the type of the rubber matrix were detailed then on the second hand effects of the MWCNT concentration and finally the effects of the coupling agent were demonstrated. 3.1. Effect of the change in the rubber matrix on the tensile properties In the present work effects of multi-walled carbon nanotubes (MWCNT) in three rubber matrices (signed as R-I, R-II, R-III) with different tensile strengths were investigated. Different effects were measured for the rubber matrices (Figure 2). Introduction of MWCNTs into the rubber either in treated or in untreated form resulted in both increase and in decrease of the tensile strengths. 0,0 4,0 8,0 12,0 16,0 20,0 R‐I R‐II R‐III Te ns ile  s tr en gh t,  M Pa Sign of the rubber matrix rubber matrix untreated MWCNT treated MWCNT Figure 2: Effects of type of the rubber matrix on tensile properties (1wt% MWCNT-content) Different effects were measured for the samples where treated MWCNTs were incorporated. Tensile strength enhanced from 8.6 MPa to 11.6 MPa meaning a 35% increase for the R-I matrix. Meanwhile in the case of R-II signed rubber the tensile strength reduced by 26% in the presence of untreated MWCNT. Application of the coupling agent improved the tensile strength by 12% but tensile strength of the original matrix could not be achieved. Tensile strengths of the MWCNT containing composites did not differ to that of the R-III matrix having the highest tensile strength (19.2 MPa). 0,0 4,0 8,0 12,0 16,0 20,0 R‐I R‐II R‐III Te ns ile  s tr en gh t,  M Pa Sign of the rubber matrix rubber matrix untreated MWCNT treated MWCNT Figure 3: Effects of type of the rubber matrix on fatigue tensile properties (1 wt% MWCNT, fatigue conditions: 100 cycles and 10 N) Resistance of the samples against fatigue tensile stresses of 100 cycles and 10 N as loading force were also studied (Figure 3). Comparing the results of the fatigue tensile tests to those of the static tensile tests two important outcomes could be stated. First of all MWCNTs in the rubber blends could either improve or deteriorate the mechanical properties depending on the type of the rubber matrices. On the second hand composites made from basic mixture of R-II showed different behaviour than the others. Fatigue tensile strength was found to have been deteriorated by 6.5% if the MWCNT was incorporated in untreated form. The opposite behaviour was experienced by MWCNTs treated by the coupling agent since a 5% increase was measured. Standard deviation (SD) was calculated to be 0.8 MPa for unteated and 1.0 MPa for surface treated MWCNT containing samples. Elongation at break was also represented for both types of tensile tests (Figures 4, 5). 0 50 100 150 200 250 300 350 400 R‐I R‐II R‐III El on ga ti on  a t  br ea k,  % Sign of the rubber matrix rubber matrix untreated MWCNT treated MWCNT Figure 4: Effects of type of the rubber matrix on elongation at break (1 wt% MWCNT content) 72 Considerations for the elongation at break were established similar to the tensile strength. Type of the rubber was determinative in the evolution of the elongation at break (Fig. 4) either. Reinforcing rubber R-I with MWCNTs the value of 250% of elongation at break significantly decreased due to the pristine MWCNTs. Changing the reinforcement to surface treated MWCNTs an 18% improvement could be measured as the property increased to 290%. MWCNTs even in coupling agent treated form deteriorated the elongation at break of R-II rubber. 0 50 100 150 200 250 300 350 400 R‐I R‐II R‐III El on ga ti on  a t  br ea k,  % Sign of the rubber matrix rubber matrix untreated MWCNT treated MWCNT Figure 5: Effects of type of the rubber matrix on elongation at break for fatigue tensile tests (fatigue conditions: 100 cycles and 10 N, 1 wt% MWCNT) Elongation at break did not change if the matrix with the highest elongation was reinforced with MWCNTS either in untreated or in surface treated form. Regarding to the results for elongation at break after the fatigue tensile tests a more balanced picture could be drawn. Approximately a 20% decrease was measured for R-I and R-II matrices in the elongation at breaks for fatigue tensile testing compared to static tensile testing. But MWCNT containing composites had the same values for elongation at break both for R-I and for R-II based samples even for fatigue tensile tests. There were not any significant effects of the coupling agent on the elongation at break of all the rubber matrices. 3.2. Effect of carbon nanotube concentration In that chapter changes in tensile strength, tensile modulus and elongation at break of R-III based composites was discussed in function of the concentration of the MWCNT. Lower tensile strength was measured for R-III matrix after fatigue tensile tests (Figure 6). Regarding to the static tensile strength approximately 1.5 wt% MWCNT was required for a slight increase. The fatigue tensile results were represented for the same fatigue load (10 N) with two different cycles: 100 and 1500 cycles (Fig. 6). Resistance of the rubber (R- III) deteriorated with the duration of the fatigue test. The same trends were observed for carbon nanotube containing samples either. 2.4 wt% MWCNT was needed to exceed the tensile strength of R-III after long time fatigue stresses. With lower concentration of MWCNTs in the rubber there was no difference among the property at the same fatigue conditions. 14 16 18 20 R‐III 1.0wt% MWCNT 1.5wt% MWCNT 2.4wt% MWCNT Te ns ile  s tr en gh t,  M Pa without fatigue 100 cycles 1500 cycles Figure 6: Effects of carbon nanotube concentration on the fatigue tensile strength (fatigue load: 10 N for both 100 cycles and 1500 cycles) Figure 7 represented the effects of filler concentration on the tensile modulus. On the first hand, values of modulus by the static tensile test increased with the MWCNT content. The modulus of the samples containing 1 wt% MWCNT have been enhanced by 13% related to the reference. The same extent of improvement was measured for the other two MWCNT/rubber composites. Fig. 7 showed the results for fatigue tensile test either. Depending on the duration of the fatigue tests positive changes were getting lower with increasing MWCNT contents. In that case moduli for the fatigue conditions were compared to the results of the simple tensile test. All the reinforced samples performed higher tensile modulus than that of the rubber matrix, so toughness of the composites enhanced by incorporation of MWCNTs. The modulus of the sample with 2.4 wt% MWCNT depended the less on the duration of fatigue stresses. That phenomenon could be related to orientation of the MWCNTs into the direction of the periodic stresses based on previous experiments with carbon fibres. 0 2 4 6 8 R‐III 1.0wt% MWCNT 1.5wt% MWCNT 2.4wt% MWCNT M od ul us , M Pa without fatigue 100 cycles 1500 cycles Figure 7: Effects of carbon nanotube concentration on fatigue tensile modulus (fatigue load 10N) Figure 8 reperesented changes in the elongation at break in the function of the MWCNT content. Elasticity of the samples had been expected to decrease with the MWCNT content. Thus, a reduction in elongation at 73 break was observed above 1 wt% MWCNTs in the rubber. Not a significant change was calculated for 1 wt% MWCNT/rubber samples. Samples containing 2.4 wt% MWCNT had a value of 300% for elongation at break meanwhile the same property was 345% for the basic rubber. 0 50 100 150 200 250 300 350 400 R‐III 1.0wt% MWCNT 1.5wt% MWCNT 2.4wt% MWCNT El on ga ti on  a t  br ea k,  % without fatigue 100 cycles 1500 cycles Figure 8: Effects of carbon nanotube concentration on fatigue elongation at break (fatigue load 10 N) 3.3. Effect of surface treatment In that part of the paper effects of surface treatment were discussed on tensile and fatigue tensile properties. In Figures either results of the unreinforced rubber matrix with composition R-III or results of the composites containing 2.44 wt% MWCNT reinforcement were demonstrated. During the fatigue tensile tests a fatigue force of 10 N was applied with different duration times (100 and 1500 cycles). Figure 9 represented the effects of untreated and coupling agent treated MWCNTs on tensile strength and fatigue tensile strength of the unfilled rubber. Changes for simple tensile test could be not significant both for untreated and treated MWCNT/rubber samples containing the same concentration of MWCNT.

However, the composite containing surface treated MWCNTs afforded more balanced performance even for a long period of fatigue stress (1500 cycles) in the given range of concentration and the coupling agent has a higher stabilizing effect in the composite. 0 2 4 6 8 R‐III MWCNT 2.4% MWCNT 2.4% (treated) M od ul us , M Pa without fatigue 100 cycles 1500 cycles Figure 10: Effects of surface treatment on fatigue tensile properties of the composites (fatigue load: 10 N) In Figure 10 the effects of the surface treated MWCNTs were demonstrated on the tensile moduli in function of number of fatigue cycles. Due to application of MWCNTs in the rubber matrix the values of modulus enhanced compared to the rubber since the aforementioned reinforcing material can increase toughness of plastics, elastomers and rubbers. Resistance against fatigue stresses were also showed in Fig. 10. The values of modulus have been increased both for untreated and treated MWCNT containing samples compared to the initial rubber matrix independently from duration of the fatigue stress. Almost the same moduli were determined for both MWCNT/rubber composites at the same level of fatigue conditions. Surface treatment was concluded not to have significant effects on tensile modulus but more balanced behaviour was experienced for treated MWCNT/rubber samples. 0 50 100 150 200 250 300 350 400 R‐III MWCNT 2.4% MWCNT 2.4% (treated) El on ga ti on  a t  br ea k,  % without fatigue 100 cycles 1500 cycles Figure 11: Effects of surface treatment on fatigue tensile properties of the composites (fatigue load: 10 N) Figure 11 demonstrated the effects of both forms of MWCNTs on the elongation at break for distinct fatigue duration. Values of elongation at break for MWCNT/ rubber composites were measured to be below the value of the rubber matrix. The trends were the same both for simple and for fatigue tensile tests. Results were observed to be more balanced for coupling agent treated MWCNT reinforced rubber in that point of view too. Although elongation at break for the original rubber matrix was the highest among all the 74 samples regarding the tensile test but after a longer fatigue tensile test significant (13%) deterioration was obtained and the value of the treated MWCNT/rubber was less sensitive against fatigue stresses. 3.4. SEM Homogeneity of the samples based on R-I rubber was studied on the SEM graphs of the broken surface of the composites (Figure 12–14). Figure 12: SEM graph of the broken surface of the original rubber matrix Figure 13: SEM graph of the broken surface of the pristine CNT containing rubber composite Figure 14: SEM graph of the broken surface of the coupling agent treated CNT containing rubber composite Components of the rubber formula were clearly remarked (white spots) on SEM graph of all the samples. Difference was observed between the carbon nanotube containing samples. Composites with untreated CNTs showed a less smooth surface after tensile test than samples with surface treated reinforcements. Narrower and more homogeneous particle size distribution was experienced on the surface of coupling agent treated carbon nanotube/rubber samples indicating higher degree of compatibility of the components which could probably result the improvement of the mechanical properties. Conclusion Our research has been directed to the application of MWCNT in rubbers in which effects of an olefin- maleic-anhydride based coupling agent was also studied. The results were summarized as follows: - Application of carbon nanotubes in a rubber matrix could both enhance and deteriorate the mechanical properties of the composites depending on the types and strength of the original rubber mixture. - Difference in the behaviour in MWCNT containing composites could be experienced during the fatigue tensile test, which could be important especially for rubber products. - At least 2.4 wt% MWCNT was required to achieve better performance during long time fatigue than the rubber matrix with the highest tensile strength (R-III).

LUKACS Indexon Ltd., 8 Veres acs Str., 6725 Szeged, HUNGARY E-mail: lukacs.zoltan@indexon.hu The conventional potential measurements and evaluation methods of cathodic protection diagnostics do not give reliable results in some practically important cases: in systems where the whole amount of cathodic protection current cannot be interrupted for any reason or the equalizing currents affect the protection to a significant level or interference with other cathodic protection systems is encountered. The paper discusses a model and its practical application dealing with these difficult cases. The test measurement evaluation results justify the theoretical model. On the basis of the theory a very simple measurement method is proposed for the determination of the coating defects IR-free potentials. Keywords: cathodic protection, IR-free potential, pipeline corrosion, coating defect 1. Introduction The cathodic protection is a widely used, robust and reliable method of corrosion protection of underground pipelines, tank bottoms and underwater parts of immersed structures, e.g. ships and drilling platforms. In the past eight decades a lot of experience has been accumulated concerning the applicability and limitations of cathodic protection. In the most widespread type of cathodic protection, the impressed current systems, the structure to be protected is connected to the negative output of a DC current source („CP station”) and the positive output is connected to a so-called earthing anode which serves for the closing of the electrical circuit (see a typical arrangement for a cathodically protected pipeline in Figure 1). The output of the DC source is variable and, in modern devices, can be regulated, either for constant potential or for constant current. If no cathodic protection is applied to a structure corroding in water or soil and no net current is flowing through the structure, then the sum of the anodic (corrosion) and cathodic currents is zero. The ultimate criterion of the effectiveness of cathodic protection is the level of suppression of the anodic current. This can be achieved with the cathodic polarization of the structure. The decrease of the anodic current cannot be measured directly. However, if the applied potential is sufficiently negative (cathodic) then the anodic current (and the corrosion rate) is suppressed, with increasing cathodic polarization theoretically beyond any limit; practically a decrease of 1–2 orders of magnitude can be implemented, which is satisfactory for the practical requirements in most cases. In conclusion, the negative polarization of the structure results in the suppression of the anodic current (this was the goal) and in the increase of the cathodic current, which is an unavoidable consequence of the potential shift, sometimes with unfavourable side effects. During the past decades a lot of empirical experience has been accumulated concerning the optimal operation conditions of cathodic protection. It has been assumed for a long time that cathodic protection has the best performance in typical applications in soils if the electrode potential of the structure is more negative than -850 mV, measured against a saturated copper/copper sulphate electrode [1] (its standard potential at 25°C is - 320 mV; all potential data will be given against this type of reference electrode unless specified otherwise). The lower limit of the potential varies for different applications but it is typically assumed to be between 1100 and 1300 mV1. The electrode potential, as discussed above, is the potential that can be measured with a reference electrode placed to the direct vicinity of the electrode, i.e. which does not include any component from the ohmic potential drop through the electrolyte2. This potential, called as IR-free potential, is a central concept in cathodic protection. 1 At more negative potential the excessive rate of cathodic current may have adverse effects on the structure or on the coating. 2 There is another source of the ohmic potential drop, namely, the drop in the electric conductor, which can also be significantly high in the case of pipelines, but this source will not be dealt here; in this paper the ohmic drop is understood as the ohmic potential drop through the electrolyte between the anode and the cathode. 78 Figure 1: Schematic arrangement of cathodic protection and potential measurement circuitry The determination of the exact value of the IR-free potential is practically impossible in case of buried structures and with conventional methods. This paper is dealing with the mathematical properties of the electric field of the cathodic protection system and provides a simple method to give a good approximation of the IR- free potential, with significant practical advantages that are facilitated by making use of the remote earth potential. The discussion below is dealing specifically with the case of coated, buried and cathodically protected steel pipelines. However, the situation with tanks bottoms and other buried structures is quite similar. For offshore and underwater structures the theory also applies but the application technology is slightly different – these cases will be dealt with in separate communications. 2. Discussion 2.1. Review of the conventional ways of determination of the IR-free potential In the first times of application of cathodic protection the cathodic protection was assumed as effective if the polarized potential was more negative to the open- circuit potential. It was realized very soon that the measured potential value was dependent on the location where the reference electrode was placed (owing to the location-dependent ohmic potential drop) and the need of a criterion of effectiveness was also recognized. The determination of the IR-free potential was carried out by the switching off the current source. This technique is routinely used in the laboratory electrochemical measurements, too. The determination of the ohmic drop compensated corrosion potential of a cathodically protected structure has an enormous literature. A short but concise general overview on the topic was given by Bushmann and Rizzo [2]. In the standard practice of cathodic protection nowadays the determination of the IR-free potential is carried out by periodically switching the current source off and on. Typically a pattern of 2–4 seconds switched on and 0.5–1 second switched off is implemented (the time values may also vary in a wider range). The potential measurements are carried out after a delay of at least 0.1 second, in order to eliminate the effect of the inductive transients (these appear in case of long pipelines and large currents only). The potentials measured with CP stations turned on and off are generally named as ON potential and OFF potential respectively. Under field conditions in many cases it is nearly impossible or at least very cumbersome, expensive and time-consuming to switch all the CP stations that are effective in a certain area. If some of the current sources remain switched on while measuring the OFF potential that results in a major bias in assessing the IR-free potential. This bias may be up to a few hundreds of millivolts in extreme cases, and often leads to erroneous conclusions with respect to the level of protection of structures, sometimes with serious consequences. In spite of these obvious deficiencies, in the industrial practice in most cases the measured OFF potentials are identified with the IR-free potentials. Another source of the uncertainties in assessing the IR-free potential via the OFF potentials is the ohmic potential drop generated by the equalizing currents flowing between the more and less polarized parts of the structure. Stray current sources can also falsify the conventional IR-free potential determinations via the measured OFF potentials. Nowadays typically GPS-driven, high precision clock operated interrupters are applied in CP measurements, which facilitate an increased measurement precision and reliability. Some manufacturers also provide CP stations with built-in interrupters and remote control options. 2.2. An alternative way of calculation of the IR-free potential from measurement data In spite of the enormous progress in measurement technique and the apparent inadequacy of the determination of the IR-free potential via the OFF-potential, no much progress has been achieved in the theory and in the evaluation of the measurement data. Let us assume a cathodic protection system with an anode and a single coating defect at some part of the protected structure. The potential profile as a function of the distance between the coating defect and the anode is shown in Figure 2. The potential field of the coating defect is defined as the domain where the potential is more negative than the remote earth potential and the potential gradients are directed towards the coating defect. Figure 2: Potential relations in the area of the anode and the coating defect Surface equipotential lines Coating defect Test point Potential meter Reference electrode Protected pipeline CP station Anode Interrupter with timer Current flux vectors 79 Let us mark two points in the potential field of the coating defect as P1 and P2. These two points determine two equipotential surfaces that surround the coating defect. Also, these equipotential surfaces mark a domain of the space with a definite and constant (i.e. independent from the current flux) electrical resistance. Let R1 and R2 be the ohmic resistance between the coating defect and the points P1 and P2 respectively. Further on, let us assume that some perturbation is applied to the CP system, i.e. the current is interrupted (completely or partially – it is indifferent from the point of the model). From Ohm’s Law it follows that OFF OFF x x I EER 0− = , OFFON OFF x ON x x II EER − − = , (1a, b) where x=1.2 refers to any of the two surfaces and the ON and OFF superscripts refer to the potential or current in the respective states. E0 is the IR-free potential of the coating defect3. Expressing Rx and rearranging the equation, the IR- free potential can be expressed as: ( ) OFFON OFF ON x OFF x OFF x II IEEEE − −+=0 . (2) If IOFF=0, i.e. all the current is switched, then Eq. 2 is simplified to E0=EOFF, that is, the measured OFF potential is equal to the IR-free potential. However, if IOFF≠0 then the determination of EO from Eq. 2 is impossible, because the current values are indeterminable. Let IOFF and ION be expressed from the rearrangement of Eq. 1a (for the determination of ION the OFF superscripts have to be changed to ON, but this is allowed because the equation is valid also in the ON state of the system). From Ohm’s Law it is obtained that 2,1 21 R EEI OFFOFF OFF − = , (3a) 2,1 21 R EEI ONON ON − = , (3b) where R1,2 is the resistance between the two distinct equipotential surfaces. Substituting Eq. 3a and Eq. 3b into Eq. 2 it follows that ( )( ) ( )OFFOFFONON OFFOFF ON x OFF x OFF x EEEE EEEE EE 2121 21 0 −−− − − += , (4) where x=1.2. 3 Throughout in this paper it is assumed that the polarization resistance is negligible to the ohmic resistance of the soil between the coating defect and the point of the reference electrode. In most practical cases of buried structures in soil this assumption is valid. Effects of the transient decay of the charge/discharge of the electrochemical double layer and other transients related to the inductivity of the pipelines will be dealt with in a separate paper. By means of Eq. 4 the IR-free potential is obtained from measurable potential data also in the case if the current, flowing to the coating defect, is interrupted only partially or perturbated in any other way. Let us introduce the following notation: )()( 2121 21 OFFOFFONON OFFOFF EEEE EE −−− − =ρ , (5) and note that ρ is the quotient of the “not switched” and “switched” currents, flowing to the coating defect, and thus is invariant within the potential field of a certain coating defect. ρ is named foreign current ratio hence because it denotes the ratio of the foreign (i.e. not switched) and switched current. Using Eq. 5, Eq. 4 can be rewritten as ρ)( ONOFFOFF EEEE −+=0 , (6) where the x subscripts are no more needed because the equation is valid for potentials measured at any point in the potential field of the coating defect. By means of this calculation the value of the IR-free potential, which is not directly measurable if any current is flowing in the OFF state, can be determined by means of measurable potential data. An equation formally analogous to Eq. 6 had earlier been reported by Baeckmann and Schwenk [3], but the evaluation presented in their work is started from a quite different approach and also their conclusions are very different. The practical implementation of their measurement method is published in [4]. An important consequence of Eq. 6 is that E0 and ρ are linearly dependent if EOFF and EON are substituted with the constant values of the remote earth potentials: ρ)(0 ONOFFOFF EEEE ∞∞∞ −+= , (7) Taking into consideration that for the determination of ρ it is not necessary to connect to the structure with a measurement cable because it is calculated from the differences of potentials at two different places in the ON and OFF state (cf. Eq. 5 and Fig. 1), Eq. 7 provides a simple and fast method to determine the IR-free potential of coating defects where there is no test post in the vicinity. This method is a powerful alternative of the widely used CIPS (Close Interval Potential Survey) or intensive surveys [4]: the coating defect IR-free potentials are practically calculated from potential gradient data and the remote earth potentials recorded with a static data logger. Further, by fitting the data received on different coating defects in a cathodic protection system using Eq. 7, it is possible to provide data quality control facility: those data which are not fitting on the linear relationship and deviate over a threshold value are to be discarded. This is a unique feature in the practice of cathodic protection. 80 2.3. A practically important case: more coating defects in a system The calculation in Section 2.2 is strictly valid if the cathodic protection system includes one anode and one coating defect. Obviously, real systems are more complicated. Further difficulty is that in real systems the potential of the coating defects is varying; small coating defects with less ohmic potential drop4 can be polarized to a more negative potential than the larger coating defects. This potential difference between the coating defects generates equalizing currents superimposed on the cathodic protection current and, consequently, on changing of the shape of the cathodic protection current vector space, the shape of the equipotential surfaces will be also changed. Therefore the resistance between two equipotential surfaces, denoted as R1,2 above, will not be the same quantity for the ON and the OFF state in Eq. 3a and Eq. 3b. This problem can be diminished by selecting the optimal measurement points for which the equipotential surfaces have the possible smallest distortion caused by the equalizing currents of vicinal coating defects. Obviously, the closer the measurement point is to the coating defect the less the shape of the equipotential surface varies on changing of the equalizing current flowing to/from the vicinal coating defect. On the other hand, the remote earth potential is also invariant to the local changes in the vicinity of any coating defect. In conclusion the point nearest to the coating defect (where the measured potential has an extreme as a function of the surface coordinates) and the remote earth potential are to be chosen to maximize the precision of the determination of the IR-free potential. 3. Experimental verification 3.1. Conditions In order to verify the above conclusions, a test measurement was conducted on a pipeline. The pipeline was a DN 300 gas transfer line with polyethylene coating which was known to be in a bad condition. The measurement was a modified CIPS carried out with a CPM 401 universal cathodic protection diagnostic measurement system. Unlike conventional CIPS measurements, here the two reference electrodes of the mobile data logger measured different potentials: one reference electrode (electrode No. 2) was measuring the potential above the pipeline and the other electrode (electrode No. 1) was measuring the potential some 3 m apart from the pipeline (cf. Fig. 1). In this way the potential gradient, perpendicular to the axis of the 4 A smaller coating defect has a higher resistance. However, the resistance of a coating defect decreases (approximately) linearly with the diameter of the coating defect, while the electrode surface increases with second order. Therefore a larger coating defect will always give larger ohmic potential drop in case of a similar geometry. pipeline, was determined both for the ON and OFF states from the data of the mobile data logger. The switching time was 3 second ON and 1 second OFF, the delay time after the switching was 0.1 second and the sampling time was also 0.1 second. The remote potentials were measured with a static data logger. 3.2. Results The ON and OFF potential data for the two mobile reference electrodes and the remote potentials are shown in function of the distance in Figure 3, which also includes the IR-free potentials calculated for the localized coating defects determined by means Eq. 4 and Eq. 7. The IR-free potential as a function of the foreign current ratio (both determined from the data of the mobile data logger, based on Eq. 4 and Eq. 5) are shown in Figure 4, with the best fitting line. As follows from Eq. 7, the slope of this linear relationship gives the difference of the remote earth ON and OFF potentials and the intercept gives the remote earth OFF potential. The obtained data, compared to the average of the experimentally measured ones are included in Table 1. The “calibration curve” of the IR-free potentials obtained from Eq. 4 and from Eq. 7, using the remote earth potential data and the foreign current ratio obtained from the mobile logger data are shown in Figure 5 (the line is the y=x calibration line) and the numerical values, with the absolute value of the differences are shown in Table 2. 3.3. Evaluation In Fig. 3 six well developed coating defects are localized. The coating defects at 24 and 40 meters are very large, most likely they are more or less continuous series of coating defects of different sizes and positions. They are assumed to be “open” coating defects, where the damaged coating does not cover the exposed pipe area and the larger the coating defect the more positive the IR-free potential. The coating defect at 68 meter is presumably a blistering, because the apparent size is very small but the IR-free potential is very positive which is the sign of high ohmic potential drop due to the “coverage” by the damaged coating. The coating defects at 95, 125 and 130 meters are decreasing in apparent size but shifting to positive direction in IR-free potential and from this tendency it is assumed that their “coverage” is increasing. In conclusion, coating defects of different sizes and types are detected on the selected relatively short pipe section. 81 Figure 3: Measured and calculated potential data of the test measurement vs. distance Figure 4: IR-free potential data, calculated via Eq. 4, vs. Foreign Current Ratio Figure 5: Calibration of IR-free potential data calculated via Eq. 7 vs. IR-free potential data calculated via Eq. 7 Fig. 4 justifies the assumptions of Eq. 7. The linear relationship between the foreign current ratio and the IR-free potential has a “double nine” (0.993) correlation coefficient. This data has to be qualified considering the extreme differences in type and size among the coating defects. This relatively good result has to be considered also in the light of the fact that the first two defects are actually a series of defects, which decreases the applicability of the theory of the equipotential surfaces. In short, these circumstances can be considered as a near-worst-case scenario. According to Eq. 7, the remote potentials can be determined from the IR-free potential vs. foreign current ratio plot. From Tab. 1 a moderate difference of a few tens of millivolts is concluded which justifies the theoretical expectations.

Fig. 1)). In Tab. 2 it is shown that the error of the determination of the IR-free potentials using Eq. 7, compared to the data using Eq. 4, are an average of 13 mV which is far below the practically required precision limit. Summary It has been shown that based on the concept of the equipotential surfaces and Ohm’s Law a linear formula can be provided for the determination of the IR-free potential. The precision of the formula is the highest if the points used for the determination of the foreign current ratio are the points nearest to the coating defect (i.e. where the measured potential data have an extreme) and the remote earth. The theory also provides the value of the foreign current ratio. It was pointed out that the foreign current ratio and the IR-free potential are in a linear relationship where the coefficients of the linear relationship are related to the remote earth ON and OFF potentials. This relationship establishes the connection between the “global” remote 82 and the locally, above the pipeline measured potentials. Also this relationship provides an alternative method for the assessment of the IR-free potential, which does not require a measuring cable to be pulled alongside the pipeline. All these theoretical results were confirmed with a test measurement made on a section of pipeline with coating defects of different size and type. The evaluation of the test measurements justified the theoretical assumptions and proved that the determination of the IR-free potential, based on the measurement of the over- the-line potential gradients and the remote ON and OFF potential, is applicable and accurate enough for the practical requirements.

They produce broad-spectrum antibiotics, which can be applied in several different fields where suppression of microbes is needed. These antibiotic molecules have different chemical structure such as peptides. Analysis and identification of these molecules provide useful ways in the research and development of drugs and agrochemicals. Keywords: entomopathogenic bacteria, antimicrobial activity, peptides, analysis Introduction Insect pathogenic or entomopathogenic nematodes (EPN) and their symbiotic entomopathogenic bacteria (EPB) can be used as microbial control agents against agricultural insect pests [1]. These nematodes of Heterorhabditis and Steinernema species are symbiotically associated with the members of the bacteria family Enterobacteriaceae as Photorhabdus and Xenorhabdus species, respectively [2–3]. The EPB have several special functions in this symbiotic relationship. One of them is the production ability of broad-spectrum antibiotics, which keep monoxenic conditions in insect cadavers in soil [4]. Antibacterial resistance is increasing worldwide. The compounds produced by EPN symbiotic bacteria have showed a wide range of bioactivities of medicinal and agricultural interest, such as antibiotic, antimycotic and insecticidal effects [5]. These antimicrobial peptides have been successfully applied in pharmaceutics, plant disease control and many other fields [6]. Antimicrobial peptides have many beneficial characteristics, such as broad-spectrum antibiotic activity, thermal stability, and low molecular weight, and most significantly, compared with most antibiotics, they are not easy to lead to the development of resistance in the target [7]. These compounds were reported as showing in vitro activity against Gram-positive bacteria, including for example the multi-drug resistant strain of Staphylococcus aureus. They have diverse chemical structures including peptides as well [5]. Analytical study of these molecules can be achieved in different ways. Edman degradation, developed by Pehr Edman [8], is a method of sequencing amino acids in a peptide. In this method, the amino-terminal residue is labeled and cleaved from the peptide without disrupting the peptide bonds between other amino acid residues. A major drawback to this technique is that the peptides being sequenced in this manner cannot have more than 50 to 60 residues (and in practice, under 30). The peptide length is limited due to the cyclical derivatization not always going to completion. The infrared spectrum of a protein provides a wealth of information on structure and environment of the protein backbone and the amino acid side chains [9]. This makes infrared spectroscopy an extremely useful tool for the investigation of protein structure. The absorption of a side chain in a protein may deviate significantly from their absorption in solution or in crystal. The special environment provided by a protein is able to modulate the electron density and the polarity of bonds, thus changing the vibrational frequency and the absorption coefficient. Therefore, the band positions given in reviews should be regarded only as guidelines for interpretation of spectra [10]. In this study, we aimed the isolation and analysis of some peptide-type antibiotic compounds from two EPB strains. 84 Material and methods Antibacterial peptide-producing entomopathogenic bacteria were Xenorhabdus budapestensis (EMA) and Xenorhabdus szentirmaii (EMC). They were cultured in Luria Broth (LB and LBA) liquid and solid media as previously described [11]. Cell-free culture media (CFCM) were prepared as follows: aliquots of the stock culture were added separately into 900 mL sterile medium. The flasks were incubated in a shaker at 200 rpm and 30ºC for 24 h and centrifuged at 13 000 rpm (10 000 g for 30’). After centrifugation the supernatant was filtrated through Express Plus filter (0.22 µm) (Merck Millipore). Purification of antimicrobial compounds: 1000 mL of CFCM was mixed with activated Amberlite XAD polymeric adsorbent in a 1:20 ratio and incubated for 24 h. The resin-CFCM mixture was filtered through Millipore Express Plus filter of 0.22 µm pore-size and washed subsequently with 200 ml of distilled water, 200-200 ml of 25 V/V%, 50 V/V% and 80 V/V% methanol (MeOH), removing all inactive compounds by this way. After this the resin was washed with 200 ml cc. MeOH:HCl (99:1) and 200 ml i-propanol (iPrOH) to eluate biologically active compounds. These samples were evaporated by vacuum distillation and resulted samples with MeOH and iPrOH, respectively. For the analysis of the purified antimicrobial compounds a Thermo Nicolet AVATAR FT-IR-330 FT- IR apparatus was used to determine FT-IR spectra and a Hitachi U-2910 UV-Vis spectrophotometer was used to form the UV spectra. Solid samples were prepared for the IR: some quantity of samples were ground with purified KBr and this mixtures were pressed in a mechanical press to form a transparent pellet through which the beam of the spectrometer can pass. Resolution: 2.000 cm-1, Scans: 16. Results and discussion The most precise method for the protein and peptide identification after their separation by high-performance liquid chromatography (HPLC) is mass spectrometry [12]. However, this method is quite expensive. Absorbance at low wavelength (<220 nm) detects peptide bonds and amino acid residues with detection limits between nanomoles and picomoles. Peptides having aromatic residues (phenylalanine (Phe), tyrosine (Tyr), and trypthophan (Trp)) can be detected at 254 or/and 280 nm. For this reason we made a UV spectra of the purified antibiotic activity compounds. Results of these measurements are shown in Table 1. Table 1: UV absorbance (nm) of the antibiotic compounds EMA EMC iPrOH MeOH iPrOH MeOH 201 203 200 202 213 218 - 217 IR spectra were made with the above described method. Results of these measurements are shown in Figures 1–4. Figure 1: Antibiotic compounds purified with iPrOH from EMA Figure 2: Antibiotic compounds purified with MeOH from EMA In the case of amino acids only two side chain moieties absorb in spectral regions that are free from overlapping absorption by other groups and thus allow the spectroscopists an unambiguous assignment without further experiments. These are the SH group of cysteine (2550–2600 cm-1) and the carbonyl group of protonated carboxyl groups (1710–1790 cm-1). These groups were obtained in none of the IR spectra. Figure 3: Antibiotic compounds purified with iPrOH form EMC 85 All other side chain absorption overlap with the absorption of other side chains or of the polypeptide backbone and further experiments are needed to assign an absorption band to a specific side chain moiety. Figure 4: Antibiotic compounds purified with MeOH from EMC The ν(C=O) vibration of glutamine side chains near 1680 cm-1 is a relative strong infrared absorber, the bands are sensitive to H-bonding and the band position is lower the stronger the H-bond is (Table 2, 3). The ν(C=O) vibration of the deprotonated carboxylate group of the glutamate shows two strong bands near 1400 and 1570 cm-1 for symmetric and antisymmetric stretching vibration, respectively (Tab. 2, 3). The ν(CN) vibration of histidine is a useful band near 1100 cm-1 (Tab. 2, 3). Tyrosine is a relatively strong infrared absorber due to its polar character. The most intense bands originate from ν(CC), the ν(C-O) and the δ(COH) mode near 1517, at 1235–1270 and at 1169–1260 cm-1 (Tab. 2, 3).

The only tryptophan bands with considerable infrared intensity seem to be those at 1334 and 1455 cm-1 (Tab. 2, 3).

TÓTH , É. LÖVITUSZ, N. NEMESTÓTHY, K. BÉLAFI-BAKÓ University of Pannonia, Research Institute on Bioengineering, Membrane Technologies and Energetics, 10 Egyetem Str., 8200 Veszprém, HUNGARY E-mail: tothgabor2@gmail.com Hydrogen sulphide is one of the most important substances responsible for unpleasant odour emissions in gas phase. It is often formed in higher concentration beyond other sulphur containing volatile compounds like methane thiol (MT), dimethyl sulphide (DMS) and dimethyl disulphide (DMDS). Removal of hydrogen sulphide is usually carried out by physical-chemical methods (e.g. adsorption), but nowadays some bio-processes may be considered as promising alternatives. Certain sulphur oxidising thiobacteria can be successfully applied for hydrogen sulphide conversion from gaseous streams like biogas. Various strains have been applied so far for degradation of hydrogen sulphide, they belong mostly to the group of Thiobacillus, which are autotrophic microorganisms. These autotrophic bacteria have the drawback in application that they grow slower than the heterotrophic ones and it is more difficult to control their growth. A number of chemotrophs are suitable for the biodegradation of H2S. These bacteria grow and produce new cell material by using inorganic carbon (CO2) as a carbon source and chemical energy from the oxidation of reduced inorganic compounds such as H2S.The objective of the work described here was to study the ability of elimination of hydrogen sulphide by two chemotrophic microorganisms (Thiomonas intermedia, Thiobacillus thioparus) in a batch bioreactor. The other aim was the study of the immobilization of these bacteria to different supports. Keywords: hydrogen sulphide, chemotrophic, biological oxidation Thiomonas intermedia, Thiobacillus thioparus, batch reactor, support Introduction Volatile sulphuric compounds like methane thiol (MT), dimethyl sulphide (DMS), dimethyl disulphide (DMDS) are harmful, corrosive components, and present in various gas streams, e.g. biogas [1, 2], among them hydrogen sulphide can be found in relatively high concentration. The concentration of hydrogen sulphide varies between 0,1 és 2% and depends on the quality of feed substance [3]. Utilisation of biogas is mainly hindered by its hydrogen sulphide content, therefore its removal is essential. The current technologies based on chemical removal are quite expensive, thus usage of biogas in power plants is not supported [4]. Yet, in most cases physico-chemical methods are used. Recently biological processes received some attention due to their effectiveness and low operational and maintenance costs [2], [4]. Biological removal of hydrogen sulphide can be carried out by autotrophic and heterotrophic ways. From the operation point of view heterotrophic strains are more beneficial, but mos chemoautotrophic bacteria seem suitable for degradation of the compound. These bacteria can live using inorganic carbon (e.g. CO2) as carbon source, while energy is obtained by oxidation of reduced compounds (e.g. H2S) [5]. The aim of this work was to study a suspended batch bioreactor, where chemoautotrophic aerob bacteria (Thiomonas intermedia, Thiobacillus thioparus) are able to use carbon dioxide present as carbon source, while hydrogen sulphide is converted into sulphur powder or oxidised sulphur compounds. The investigations were conducted in liquid phase by using free and immobilised cells. Materials and methods Microorganisms Thiomonas intermedia is an aerobic, chemoautotrophic bacterium, purchased in lyophilised state from the National Collection of Agricultural and Industrial Microorganisms (NCAIM Budapest, Hungary). For its growing Thiomonas intermedia broth elaborated by DSMZ (Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, Germany) was used [6]. Its composition is (g/L): NH4Cl 0.1, KH2PO4 3.0, MgCl2*6 H2O 0.1, CaCl2 0.1, Na2S2O3*5 H2O 5.0, yeast extract 1.0, 1000 ml distilled water. During the growing period pH was adjusted to 5.5–6.0, then it was incubated at 33°C temperature and 120 rpm. 88 The other, also chemoautotrophic aerobic bacterium is Thiobacillus thioparus, which was purchased from DSMZ (Germany) strain collection. Its growing parameters are the same as given in Thiomonas intermedia. The features of microorganisms are summarized in Table 1. Table 1: The features of Thiomonas intermedia és a Thiobacillus thioparus Thiobacillus thioparus Thiomonas intermedia optimal pH 5–9 5–7.5 optimal temperature [°C] 33–35 30–35 cell type Gram negative Gram negative Shape, size rod, 0.9–1.8 μm - Trophity obligate chemoautotrophic facultative chemoautotroph Energy source Thiosulphate, sulphide Thiosulphate, sulphide Oxygen demand aerob aerob Source [7] [8] Analysis To follow the concentration of hydrogen sulphide in the liquid phase a photometric method was applied. The principle of the measurement is that the sulphide in acidic environment gives a colourful reaction with N,N- dimethyl-p-phenilene diamin resulting in methylene blue, which can be measured by photometer in 670 nm after 20 min reaction time, using 5 cm cuvette (HachLange DR 3800) [9]. The advantages of the method are that easily applicable, having good reproducibility and the measuring range is wide: between 0.1 and 1.2 mg S2-/L. The composition of the gas phase was determined by Dräger X-am 7000, which is a mobile electrochemical device, able to detect hydrogen sulphide and carbon dioxide. The experiments were carried out in 250 ml, jacketed, thermostated reactor (Figure 1), where the total volume of the liquid phase was 200 ml. Its composition was: 10% inoculum, 5%, water containing 2500 mg/L hydrogen sulphide and 85% broth. The optical density of the samples were measured by a photometer (HachLange DR 3800), in 620 nm. The biochemical reactions in the reactor resulted in a decrease of sulphide content in the liquid phase. The water vapour in the gas phase disturbs the optimal operation of the gas analysis equipment, therefore the vapour had to be condensed before. Samples were taken every half an hour during the exponential growing period of the bacterium, otherwise it was taken every hour, and dissolved sulphide concentration and optical density were determined. Figure 1: Set-up of the batch reactor Immobilization The strains were immobilised in three types of supports and the process was checked in a serial of measurements. MAVICELL-B cellulose beads, alginate beads and granulated activated carbon were used in the experiments. MAVICELL-B (Table 2) is cellulose beads, widely used for immobilization of various microbes, having large adsorption surface area, thus a highly suitable support, moreover it can withstand to the corrosive effect of hydrogen sulphide. The cells can be bound on the surface of the support by adsorption. Table 2: Features of MAVICELL-B Feature Regenerated cellulose content 45–55% Ash 35–40% Particle size 2–3.5 mm Aggregate thickness 250–300 g/dm3 water uptake at 25ºC 150–200% Special pore volume 1.5–2 cm3/g Special pore surface area 8–10 m2/g Swelling increase in diameter 1.5 fold increase in volume 3 fold The other support used was alginate beads, widely used in biotechnology for immobilization of cells and enzyme, (Figure 2) by the so called entrapment technique. During jellification small hollows are formed in alginate where biocatalysts (enzymes and cells) can be entrapped. The structure of the gel is compatible with the biocatalysts, thus no chemical modification is needed [10]. Finally the granulated activated carbon (GAC) support was purchased from Airwatec s.a. (Belgium). 89 Figure 2: Alginate beads containing cells Due to its high surface area it seems also a promising support material for immobilisation of microorganisms. The features are listed in Table 3. Table 3: Features of activated carbon Parameter Value Total surface area (BET) (m2/g) 1080 pH 7.0 Water content (%) 1,1 Ash content (%) 8.6 Granules Diameter (mm) 1.0 During the experiments immobilised strains were kept in two vessels (for the two strains) and a blind one was used as a control, for all the three types of immobilization. Samples were taken from all vessels regularly, and sulphide contents were determined. Then fresh broth was given to the strains. In the end of the experiments the amount of immobilised cells (on the surface of MAVICELL and activated carbon particles, as well as in the alginate beads) – or more precisely the protein content – was measured by the modified Folin-method. Results Firstly 24 h long batch fermentations were carried out by free Thiomonas intermedia and Thiobacillus thioparus microbes. The results are shown in Figure 3 and Figure 4. As it can be seen from Figure 3 and Figure 4 after a 8–12 h lag phase bacteria started to grow, the exponential growing period was found from around 10th h till 15-16th h, then a the rate of growing was slower. All the four parameters measured confirmed that the maximal growing rate of both bacteria was at the 12–13th h of the fermentations. a b Figure 3: Concentration of hydrogen sulphide and carbon dioxide (a), dissolved sulphide and optical density of Thiomonas intermedia (b) as a function of time Moreover it can be established that both Thiomonas intermedia and Thiobacillus thioparus reduced the concentration of hydrogen sulphide in the reaction mixture, i.e. they mostly obtained energy from degradation of hydrogen sulphide (dissolved sulphide) during the metabolisms. In both Figures 3/b and 4/b dissolved sulphide concentration as a function of time shows some discrepancy, which is difficult to explain. We think that the analytical method (by photometer) may be disturbed by some nutrient compound present in the liquid phase, therefore another method should be found in future. Another reason of the strange behaviour might be that certain metabolic products were formed during the fermentation which resulted it in the second half of the experiments. 90 a b Figure 4: Concentration of hydrogen sulphide and carbon dioxide (a), dissolved sulphide and optical density of Thiobacillus thioparus (b) as a function of time Operational stability in the liquid phase The bacteria were immobilised in three different support: MAVICELL-B cellulose beads, alginate beads and granulated activated carbon. To check their work they were kept in reaction mixtures, containing nutrients and hydrogen sulphide, and samples were taken regularly. Figure 5 presents the experimental results: the variation of hydrogen sulphide concentration [mg S2-/L] compared to the control (bind) one as a function of reaction time in cases of MAVICELL-B cellulose beads (Fig. 5/a), alginate beads (5/b) and granulated activated carbon (5/c). It can be observed that a decrease in hydrogen sulphide concentration compared to the blind was measured, due to the activity of the bacteria immobilised on the support. To check this phenomenon protein content of the supports (measured in the end of the experiments by washing out the microbes from the surface of the support, or – in case of alginate – destroying the gel structure) was determined. The results are summarized in Table 4. a b c Figure 5: Operational stability of bacteria immobilised in MAVICELL-B (a), Ca-alginate (b) and activated carbon granulates (c) From the Table 4 it can be seen that the protein measurement confirmed our experimental results: considerable amount of microbes were immobilised on all of the supports. Since bacteria were entrapped in 91 alginate (not only adsorbed on the surface), much higher protein content was found in that case. Table 4: The amount of protein (microbes) measured in the various support Mavicell-B Ca- alginate GA C Thiomonas intermedia [mg DM/g carrier] 0.12 6.3 0.15 Thiobacillus thioparus [mg DM/g carrier] 1.83 7.1 2.05 It can be stated that the bioconversion processes can be followed by measuring the hydrogen sulphide concentration in the liquid phase, but the photometric determination of the total sulphide content can not be applied here. Based on the protein determination it is obvious that the microbes were able to immobilise in the supports and worked properly to reduce hydrogen sulphide concentration in the liquid phase. Evaluation As a summary it can be stated that our experiments proved: the two microbes investigated are suitable for the biological degradation, removal of hydrogen sulphide. However, the analytical method to follow the bioconversions should be improved and we should continue the experiments in gas phase. Based on the successful immobilisation and measurements in liquid phase, the bioreactor system should be redesigned to be able to operate in gas phase and to determine exactly the ability and effectiveness of the bacteria.

BORBÉLY1 1University of Pannonia, Institute of Mechanical Engineering, 10 Egyetem Street, H-8201 Veszprém, HUNGARY E-mail: borbelyt@almos.vein.hu The momentary amount of the available solar energy and the demand usually are not equal during the usage of solar energy for heating and electric power supply. So it is necessary to store the heat energy. This article shows optimal design of a new construction, sensible heat store filled with solid heat storage material. The planned heat store has cascade system formed a spiral flow-path layout. This is a conceptual model, worked out in case of packed bed with ceramic balls. The aim of the special layout is to realize better overall efficiency than regular sensible heat stores have. The new construction would like to get higher overall efficiency by long flow-way, powerful thermal stratification and spiral flow-path layout which can ensure lower heat loss. The article shows the calculation method of the simulation of the charge and discharge and the calculation method of the overall efficiency using the results of the simulations. The geometric sizes and operating parameters of the thermal energy store with the best overall efficiency were calculated using genetic algorithm (GA). The results of the calculation tasks show that a thermal energy store with long flow-way, with cascade system formed spiral flow-path layout has higher overall efficiency than an one-duct, short flow-way thermal energy store which has equal mass of solid heat storage material as the long flow-way one, mentioned before. Keywords: solar energy, heat storage, solid charge, sensible heat, optimization Introduction The possible thermal energy storing methods are: sensible heat storage, latent heat storage, sorption heat storage and chemical energy storage [1–8]. The simplest way is the storage of sensible heat, by heating a heat storage material without phase changing. The energy density of the sensible heat storage will be high if the specific heat and the density of the heat storage material are great as well [9]. Out of the materials which can be found in the environment in large quantity, the water has the greatest volumetric heat capacity (~4.18 MJ/m3K), but water can be applied at atmospheric pressure up to 100ºC only. The heat transport media of the concentrated solar power systems can be used as heat storage liquids as well. The melt of the solar salt (60% NaNO3 + 40% KNO3) is used out of these materials in concentrated solar power plants as heat storage material (operating temperature range 260–550ºC, volumetric heat capacity ~2.84 MJ/m3K [11]). It is not flammable, not toxic, and not too expensive. The volumetric heat capacity of some solid materials (magnesite, corundum) – because of their higher density – come near to the volumetric heat capacity of the water with much higher upper temperature limits (magnesite 3.77 MJ/m3K, corundum 3.3 MJ/m3K, cast iron 4.1 MJ/m3K [10]). Screened pebble stone, cracked stone (1.5– 2.5 MJ/m3K), concrete (0.8–1.8 MJ/m3K), wet soil (3.56 MJ/m3K) [10] are used as sensible heat storage materials, because they are inexpensive. The sensible heat stores are typical regenerative heat-exchangers. These are instationary thermal state heat-exchangers. The regenerators are long ago applied, great heat capacity heat stores with solid fill and with short charge-discharge cycle time (10–7200 s). My aims were to study the possible interior structure of the long-term heat stores, the charge-discharge process, to calculate the optimal geometric sizes and operating parameters of those.
