FIELD: chemistry.
SUBSTANCE: invention concerns method of catalytic reforming of gasoline fractions preceded with dehydrogenation of contained naphthene hydrocarbons enabled in series rector system at higher temperature and pressure with industrial platinoerionite-containing reforming catalyst SG-3P, containing erionite 10-15 wt % where in the first downstream reactors there is used industrial low-erionite (4-8 wt %) catalyst SG-3P-M type A. Reforming process is ensured with two catalysts added: at first catalyst SG-3P-M type A, and with catalyst SG-3P.
EFFECT: higher end product yield, improved circulated hydrogenous gas features.
