Abstract: Disclosed is a hydrorefining catalyst produced by placing a carrier into a steeping liquor for steeping, then aging, drying and activating. The catalyst contains the carrier, Mo and Co, characterized in that, based on 100 wt% of the catalyst, the catalyst contains 5-25% of molybdenum oxide, 1-6% of cobalt oxide, 0-15% of tungsten oxide, 0-4% of nickel oxide and 0-4.5% of alkali metal oxides, the pore volume of the catalyst is 0.30-0.85ml/g, and the specific surface area is 110-380m 2 /g. A compounded solvent for producing the catalyst contains simultaneously ammonia and polyamine complexing agent. The catalyst has good hydrogenation activity, high selectivity, long running time and excellent antiscorching characteristics.

Abstract: A method for preparing hydrorefining catalyst comprises the following steps: (1) mixing an aqueous ammonia solution with a polyamine complexing agent to form a mixed solvent; (2) adding a cobalt salt to the mixed solvent, dissolving the cobalt salt, and then adding a molybdenum salt and optional salts of other active components, and dissolving them to prepare an impregnating solution; and (3) impregnating a support with the impregnating solution, followed by aging, drying, and activating the impregnated support to form a hydrorefining catalyst. The hydrorefining catalyst prepared by this method has good activity, selectivity and stability in use.
