CATALYST FOR GASOLINE FRACTION REFORMING Russian patent published in 1995 - IPC

FIELD: catalytic chemistry. SUBSTANCE: catalyst has 0.2-1.2 wt.-% titanium or a mixture of platinum with promoter taken from the group: rhenium, iridium. rhodium, tungstate, molybdenum at the mass ratio of platinum and promoter (0.5-12):1, 50-75 wt.-% high-silicon zeolite type ZSM-5, ZSM-8 or ZSM-11 with silicate module 25-100, 0.4-6.8 wt.-% alkaline metal oxide lithium, or sodium, or potassium, and aluminium oxide the rest. In the process of gasoline fraction reforming catalyst provides the yield of catalysate in 24 h up to 86% in 240 h up to 85.8% octane number of catalysate is up to 104.3. EFFECT: enhanced effectiveness of catalyst. 2 cl, 1 tbl
