FIELD: technological processes.
SUBSTANCE: invention relates to processing of vacuum gas oil. Invention relates to a method for hydrotreating vacuum gas oil in the presence of a sulfided catalyst containing an active component from [Co2Mo10O38H4]6−, Co3[PMo12O40]2, Ni3[PMo12O40]2, [Co(OH)6Mo6O18]3−, [Ni(OH)6Mo6O18]2−, [Ni2Mo10O38H4]6−, [Co(OH)6W6O18]3−, [PMonW12−nO40]3− (where n = 1–11), [PVnMo12−nO40](3+n)− (where n = 1–4), Mo12O30(OH)10H2[Co(H2O)3]4 or mixtures thereof and an organic additive, such as citric acid, ethylene glycol or EDTA, in amount of 16–30 wt.% of the weight of the carrier, as well as a carrier, which is aluminum oxide, silicon oxide, magnesium oxide, zeolite, aluminosilicate, porous aluminophosphate, porous silicoaluminophosphate and a combination thereof, having a regular spatial structure of macropores.
EFFECT: high conversion in reactions of removing sulfur and hydrocracking of vacuum gas oil, resistance to coking and stability of the catalyst in severe conditions of gas oil hydrotreatment.
