Dual-functional hydrogenation catalyst

The invention relates to a dual-functional hydrogenation catalyst, which comprises a carrier and an active component. The dual-functional hydrogenation catalyst is characterized in that alumina is used as the carrier, the carrier also comprises a titanium component which accounts for 2 to 55 percent of the total weight of the catalyst based on the mass of TiO2, and the alumina accounts for 20 to 85 percent of the mass of the catalyst; the active component is molybdenum or a mixed component of molybdenum and cobalt, the cobalt accounts for 0 to 7.5 percent of the total weight of the catalyst, and the molybdenum accounts for 5.0 to 18 percent of the total weight of the catalyst; and one or more of nickel, copper and rare-earth compound serving as co-catalyst components is/are added into the catalyst, wherein the nickel accounts for 0.5 to 7.5 percent of the total weight of the catalyst, the copper accounts for 0.05 to 1.0 percent of the total weight of the catalyst, and the rare-earth compound accounts for 0.5 to 5.0 percent of the total weight of the catalyst. The prepared catalyst applied in a hydrogenation refining process for high-olefin raw materials such as coking dry gas or catalytic dry gas and the like has good organic sulfur hydrogenolysis and olefin saturation performance.
