Abstract RU 2206396 C1

FIELD: petrochemical process catalysts. SUBSTANCE: catalyst is prepared by adding, to aluminum hydroxide, ground alumino-cobalt-molybdenum catalyst in amounts 5 to 15% of the weight of aluminum hydroxide in presence of phosphoric and boric acid, after which mixture is granulated, dried, and calcined. Nickel and molybdenum salts are introduced into above prepared support by impregnation thereof with solution of indicated salts followed by drying and calcination. EFFECT: simplified technology and enhanced hydrodesulfurizing activity of catalyst. 2 ex
