(54) METHOD FOR PRODUCTION OF MOTOR FUEL COMPONENTS
(57)
FIELD: gasoline production. SUBSTANCE: gasoline fractions are processed under typical catalytic reforming conditions. Reforming products are separated into gas (hydrogen and C1 -C4 -hydrocarbons) and liquid high-octane products. Gas products are then separated in aromatic hydrocarbon hydrogenation zone, where hydrogen is bound by transferring it into mixture with cyclohexane series hydrocarbons and separated from C1 -C4 - hydrocarbon gases. The latter continuously circulate from hydrogenation zone into reforming zone and vice versa maintaining constancy in hydrogen concentration and pressure. Cyclohexane hydrocarbons are transferred into catalytic dehydrogenation reactor to be mixed with gas products of reforming. EFFECT: enhanced process efficiency due to increased yield (to 95-98%) of high-octane component based on the weight of starting gasoline fraction. 2 cl, 2 dwg, 1 tbl, 8 ex
