    Abstract: A catalyst for hydrogenation use in which the carrier of the catalyst comprises at least one compound from oxides and hydroxides of aluminum, silicon, titanium, zirconium, magnesium and iron, zeolites or silica-alumina, and the catalyst has an atomic ratio (the atomic ratio of the entire catalyst including the carrier, in the case of the use of an aluminum atom-containing substance as the carrier) of Cu/Fe/Al/(an alkali metal and/or an alkaline earth metal)/Zn=1/0.4 to 2.5/0.5 to 5.0/0.001 to 0.4/0 to 1.0. According to the present invention, a copper-iron-aluminum catalyst having markedly high activity and selectivity can be obtained, and, when the catalyst is used, higher alcohols having high purity can be obtained easily.

    Abstract: The hydrogenation catalyst comprises copper, iron, aluminum and optionally zine and a support selected from aluminum hydroxide, aluminum oxide and a mixture of aluminum hydroxide and aluminum oxide, having an atomic ratio of Cu/Fe/Al/Zn in the range of 1/(0.4 to 2.5)/(0.5 to 5.0)/(0 to 1.0). It is produced by dispersing a material for the support in an aqueous medium, depositing cupper and iron on the dispersant, further depositing thereon aluminum and sintering it. It is a catalyst for production of a higher alcohol from its methyl ester, effecting hydrogenation with an improved selectivity and activity.
