METHOD OF PREPARING ZEOLITE-CONTAINING CATALYST FOR REFORMING OF GASOLINE FRACTIONS Russian patent published in 1997 - IPC

FIELD: catalytic processes in petrochemistry. SUBSTANCE: catalyst preparation includes impregnating carrier with solution containing complex compounds of first Reise base chloride with sodium salt of promoter whose composition is depicted with formula [Pt(NH₃)₄Cl₂](0,2-1,35)Na₂EO₄ wherein E is tungsten or molybdenum. Impregnated carrier is dried and calcined. Indicated compound is prepared by mixing chloroplatinic acid or ammonium hexachloroplatinate, promoter sodium salt, and 25% ammonia solution at continuous stirring at 40-55 C and pressure 0.05-0.2 MPa for 20-30 h, while proportion of ammonia solution to platinum is maintained 30-70 cu.dm/g and, as carrier, mixture of 65% zeolite in sodium form and aluminium oxide is used. EFFECT: improved preparation procedure. 2 cl, 1 tbl
