Claims18
A method for producing a hydrogenation catalyst, which comprises impregnating a refractory inorganic oxide carrier with a solution comprising a water-soluble titanium compound, then further impregnating with an aqueous solution comprising at least one metal compound of Group 6 and at least one metal compound of Groups 8 to 10 of the Periodic Table, and thereafter heating the impregnated carrier at a temperature not higher than 300° C., wherein the titanium compound is a salt of a titanium-peroxohydroxycarboxylic acid.
