Horizontal Comparative Analysis By drawing temperature ethanol conversionimage and temperature C4 olefins selectivity image for each catalyst combination in Annex 1, and conducting horizontal comparative analysis, if the proportion and dosage of each catalyst are the same when loading in A and B, as shown in Figure 3, the two catalyst combinations have similar ethanol conversionand C4 olefins selectivity, and the loading method has little impact on the reaction [8].	cache/ajst-1825.pdf	txt/ajst-1825.txt
