GASOLINE FRACTION REFORMING CATALYST AND A METHOD FOR PREPARATION THEREOF Russian patent published in 2005 - IPC

Abstract RU 2245190 C2

FIELD: petroleum processing catalysts.

SUBSTANCE: invention provides reforming catalyst containing Pt and Re on oxide carrier, in particular Al2O3, wherein content of Na, Fe, and Ti oxides are limited to 5 (Na2O), 20 (Fe2O3), and 2000 ppm (TiO2) and Pt is present in catalyst in reduced metallic state and in the form of platinum chloride at Pt/PtCl2 molar ratio between 9:1 and 1:1. Contents of components, wt %: Pt 0.13-0.29, PtCl2 0.18-0.04, Re 0.26-0.56, and Al2O3 99.43-99.11. Preparation of catalyst comprises impregnation of alumina with common solution containing H2PtCl6, NH4ReO4, AcOH, and HCl followed by drying and calcination involving simultaneous reduction of 50-90% platinum within the temperature range 150-550оС, while temperature was raised from 160 to 280оС during 30-60 min, these calcination conditions resulting in creation of reductive atmosphere owing to fast decomposition of ammonium acetate formed during preparation of indicated common solution.

EFFECT: increased catalytic activity.
