PROBLEM TO BE SOLVED: To provide a catalyst capable of obtaining an alcohol group in high yield notwithstanding type of carboxylic acid, even if any type of carboxylic acid is used, and further to provide a method for manufacturing an alcohol group by direct hydrogenation using the catalyst. SOLUTION: The catalyst having ruthenium and tin supported on an activated carbon wherein the catalyst is a zinc chloride-activated carbon, and the volume of the microporosity of which the radius of the microporosity is not more than 10 Å is from 0.03 cm3/g to 0.8 cm3/g, the volume of the microporosity of which the radius of the microporosity is 10A-100 Å is from 0.5 cm3/g to 2.0 cm3/g, total volume of the microporosity is from 1.2 cm3/g to 3.0 cm3/g and the specific surface area is 800 m2/g to not more than 2000 m2, and a method for manufacturing an alcohol group by hydrogenating carboxylic acid in the presence of water using said catalyst are provided. |
