METHOD OF HIGH-OCTANE GASOLINE FOR CARS PRODUCING Russian patent published in 1994 - IPC

Abstract RU 2017793 C1

FIELD: chemical technology. SUBSTANCE: paraffin-naphthenic benzine fraction 80-180 C or heavy paraffin-base benzine fraction 85-210 C is subjected for hydrotreatment in head reactor in the presence of catalyst containing, wt. -% : platinum 0.35-0.45; zeolite-fozhasite 5-15; tin 0.1-0.5; fluorine 0.1-0.5, and γ -alumina promoted with 2.5 wt.-% zeolite type ZSM-8 - the rest. Then process of hydrotreatment is carried out in reactors in the presence of catalyst AP-64. Hydrotreatment in head reactor is carried out at 400-460 C, under pressure 1.5-3.0 MPa, volume rate of raw feeding 4 - 7 h-1, multiplicity ratio of hydrogen-containing gas circulation 1000 - 5000 Nm3/m3 raw. EFFECT: improved method of gasoline producing. 1 tbl
