METHOD OF PREPARING AROMATIC HYDROCARBON HYDROGENATION CATALYST Russian patent published in 2003 - IPC

FIELD: hydrogenation- dehydrogenation catalysts. SUBSTANCE: method consists in introducing tungsten and nickel compounds into carrier, said compounds being added by way of one-stage impregnation performed according to water uptake of carrier or with overflow of stabilized excess solution containing simultaneously tungsten and nickel compounds. Tungsten compound is ammonium tungstenate or tungstic acid. Solution is stabilized by adding orthophosphoric or nitric acid, hydrogen peroxide, ammonia, or their combinations. EFFECT: simplified catalyst preparation utilizing fixed-quality components and avoided use of precious metals. 2 cl, 1 tbl, 5 ex
