PP-III-57special catalyst system with protective layer FOIR-1 enabled to decrease the content ofmultiring aromatic hydrocarbons from 14,5 to 5-7 % depending on the process conditions.Table 1Process characteristics effect on the depth of extraction of sulfur compounds duringvarious processing modes.Virgin diesel fraction, S=0,62%Mix feedР, Bar (g) V C , h -1 T, o C S, ppm Р, Bar (g) V C , h -1 T, 0 C S, ppm40 1,5 330 62 40 1,5 340 9240 4,0 330 365 40 1,5 350 4850 2,0 340 40 40 1,5 350 3450 4,0 340 91 50 1,5 340 3870 2,0 330 23 50 1,5 350 4670 2,0 330 9 70 1,5 340 970 2,0 340 5 70 1,5 350 6Catalysts of grade AGKD are also recommended to be used for hydrofining of gasolinefractions and vacuum gas oil.Hydrofining of vacuum gas oil at the pressure of 5,0 MPa and feed volumetric flow rateof 1,0 h -1 enable to decrease the amount of sulfur compounds to less than 0.1 % at the sametime decreases the amount of nitrogen and coke compounds by 35-40 %. The abovementioned method is favorable for the behavior of the catalyst cracking process. Use of suchfeed enables to increase the gasoline output by 1,5-2 % at the same time decreasing theamount of such waste product as sulfur and nitrogen compounds and carbons disposed intothe atmosphere.References1.
