Claim:
1. A process for producing a hydrogenation catalyst, wherein the hydrogenation catalyst comprises components (a), (b), (c), and (d), wherein the component (a) is copper oxide, the component (b) is zinc oxide, the component (c) is a metal oxide, wherein the metal is one or more selected from the group consisting of aluminum, gallium, tin, titanium, zirconium, chromium, molybdenum, tungsten, manganese, rhenium, lanthanide metals and actinide metals, and the component (d) is one or more alkaline earth metal hydroxides, wherein a weight ratio of the component (a):the component (b):the component (c):the component (d) is 5 to 60:10 to 50:5 to 60:0.2 to 2, the process comprises: (1) producing a composite metal oxide by a coprecipitation method, wherein the composite metal oxide comprises the component (a), the component (b), and the component (c), wherein a weight ratio of the component (a):the component (b):the component (c) is 5 to 60:10 to 50:5 to 60; and (2) impregnating the component (d) into the composite metal oxide to obtain a mixture, and then filtered, dried and calcined such that the weight ratio of the component (a):the component (b):the component (c):the component (d) is 5 to 60:10 to 50:5 to 60:0.2 to 2.
