(54) METHOD FOR PRODUCTION OF MOTOR FUEL COMPONENTS (BIFORMING-2)
(57)
FIELD: motor fuels. SUBSTANCE: gasoline are processed under catalytic reforming conditions and products are separated into gas fraction (hydrogen and C1 -C4 -hydrocarbons) and liquid high-octane fraction. From the latter, C1 -C5 - hydrocarbon gases are removed in rectification column and recycled into reforming zone to be reprocessed. Recycling C1 -C5 -hydrocarbon gas is combined with additional amounts of C3 -C5-hydrocarbon gases from outside source composed of mixture of saturated and unsaturated hydrocarbons. EFFECT: increased yield of liquid high-octane component by 3-6%. 3 cl, 2 dwg, 1 tbl, 8 ex.
