PURPOSE:To obtain a copper-iron-aluminum-based hydrogenation catalyst having extremely high selectivity and high activity by using a carrier selected from silicon oxide, titanium oxide, zirconium oxide, etc., and specifying the atomic ratio. CONSTITUTION:A carrier is selected from silicon oxide, titanium oxide, zirconium oxide, magnesium oxide, iron oxide, and silica-alumina and is suspended in a water-soluble solvent. On the other hand, an alkali is reacted with a water- soluble copper salt and a water-soluble iron salt to precipitate a copper compound and an iron compound on the surface of the carrier. Then, an alkali and a water-soluble aluminum salt are reacted with a water-soluble aluminum salt to precipitate an aluminum compound on the surfaces of solid particles in the suspension. The precipitates are collected, washed with water, dried, and calcined. In this way, a copper-iron-aluminum-based catalyst having a composition with an atomic ratio of Cu/Fe/Al/Zn within the range of 1/(0.4-2.5)/(0.5-5.0)/(0-1.0) is obtained. |
