METHOD FOR PRODUCING GASOLINE FRACTIONS Russian patent published in 1999 - IPC

Abstract RU 2131905 C1

FIELD: gasoline production. SUBSTANCE: gasoline fractions are produced by catalytically converting organic stock: oxygen-containing organic wastes and by-products from different production enterprises. Conversion is carried out under hydrogen-containing gas atmosphere at elevated temperatures and pressures in presence of catalyst consisting of Pentasil-type zeolite and metal oxide component in the form of non-skeleton phase compounds and containing, wt %: ZnO 65-70, Cr₂O₃ 29-34, W₂O₅ 1; or ZnO 29-31, CuO 58- 64, and Al₂O₃ 7-9 at weight ratio of zeolite to metal oxide component (30- 50): (70-50). According to invention, process is carried out at 280-420 C in a flow-circulation system wherein gas stream from reactor is cooled, condensed reaction products are separated and part of gas stream is recycled. EFFECT: increased service cycle of catalyst at 98-100% conversion of oxygen-containing organic stock. 2 cl, 2 tbl, 6 ex
