HYDROCARBON MATERIAL HYDROFINING PROCESS Russian patent published in 1998 - IPC

FIELD: petroleum processing. SUBSTANCE: method consists in hydrofining of hydrocarbon raw material including in mixing gasoline preheated to 150-200 C with diesel fuel or vacuum gas oil preheated to 340-410 C, whereupon mixture is brought in contact with hydrogen- containing gas in presence of alumino-nickel(cobalt)molybdenum catalyst, percentage of gasoline in mixture being 2 to 50%. Method allows producing gasoline with no more than 0.04 wt % of sulfur or vacuum gas oil with no more than 0.35 wt % of sulfur, and prevents coking of catalyst bed and heating equipment. EFFECT: enhanced process efficiency. 3 cl
