PROBLEM TO BE SOLVED: To obtain a catalyst capable of producing alcohols from carboxylic acids with high activity and high selectivity by using a catalyst containing a metal selected from the group consisting of ruthenium, platinum and rhodium, a metal selected from the group consisting of cobalt, nickel, manganese and iron and rhenium. SOLUTION: At least one kind of a metal selected from the group consisting of ruthenium, platinum and rhodium, at least one kind of a metal selected from the group consisting of cobalt, nickel, manganese and iron and rhenium are added to compose a hydrogenating catalyst. Carboxylic acids are hydrogenated in a liquid phase in the presence of the catalyst to produce alcohols in a high yield. At this time, the atomic ratio of platinum to rhenium is set to 0.1-5 and the atomic ratio of cobalt to rhenium is set to 0.1-10. The catalyst is supported on a carrier to be used and, as the carrier, an inorg. porous substance, activated carbon or graphite having a large surface area is used. |
