HYDRO REFINING CATALYST

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 110-380 m2 /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 L'invention porte sur un catalyseur d'hydroraffinage produit par introduction d'un support dans une liqueur de trempage pour le trempage de celui-ci, puis vieillissement, séchage et activation. Le catalyseur contient le support, Mo et Co et il est caractérisé en ce que, sur la base de 100 %
