METHOD OF MOTOR FUEL PRODUCTION FROM OIL Russian patent published in 2001 - IPC

FIELD: oil refining and petrochemistry. SUBSTANCE: method includes primary processing of oil to produce straight-run gasoline, straight-run middle distillates and raw material for hydrogen cracking; hydrogen cracking of produced raw material and separation of gasoline and middle oil distillates; catalytic conversion of straight-run gasoline and at least heavy part of gasoline produced in hydrogen cracking with use of catalyst containing zeolite of pentasils group and hydrogenating/dehydrogenating component under conditions of formation of aromatic hydrocarbons from paraffins and naphthenes. Catalytic conversion of propane-butane fraction is effected with use of catalyst containing zeolite of pentasils group and hydrogenating/dehydrogenating component under conditions of formation of aromatic hydrocarbons and hydrogen. Mixture of products of catalytic conversion of gases and gasolines is directed for separation into hydrogen-containing gas whose at least one part is used for hydrogen cracking of propane-butane fraction which is sent for catalytic conversion, and high-octane gasoline. EFFECT: simplified process technology. 2 cl, 1 dwg, 1 tbl
