ajst-1490	Hu, Yonghong	Research on Desulfurization Technology of Low Sulfur Marine Fuel Oil	2022	2	.pdf	application/pdf	1323	60	33	The International Maritime Organization (IMO) issued the Sulfur Restriction Order, requiring the global use of low sulfur marine fuel oil with sulfur content (mass fraction) less than 0.5% in 2020[1], and the specific international marine fuel oil sulfur content limit is shown in Figure 1. However, the residual carbon is generally high and viscous, and a certain percentage of diluted oil (wax oil, catalytic cracking slurry, etc.) needs to be blended as fixed-bed feed, and the installation and operation costs are very high, thus increasing the cost of producing heavy fuel oil, so the direct production of heavy marine fuel oil with sulfur mass fraction below 0.5% by fixed-bed hydrogenation is worth further consideration[2].	cache/ajst-1490.pdf	txt/ajst-1490.txt
