METHOD OF PREPARING ZEOLITE-CONTAINING GASOLINE FRACTIONS' REFORMING CATALYST Russian patent published in 1998 - IPC

FIELD: petroleum processing and catalysts. SUBSTANCE: catalyst is prepared by impregnating carrier with solution containing mixture of platinum ammoniate, promoter compound, and sodium or potassium salt at alkali metal to platinum atomic ratio (1-50):1. Impregnation is carried out at pH 8.5 to 12 and gauge pressure 0.02 to 0.3 MPa. Thus prepared catalyst is dried and calcined. As carrier, mixture of high-silica zeolite in sodium form and alumina at 60: 40 weight ratio is advantageously used. Preferable promoter is tungsten or molybdenum. EFFECT: increased catalyst activity. 3 cl, 1 tbl
