A process for producing an alcohol by continuously passing a fatty acid ester, a fatty acid triglyceride or a fatty acid through a hydrogenation catalyst to thereby produce the aimed alcohol through catalytic reduction is disclosed, wherein the employed reactor is a fixed bed reactor in which the liquid phase and the gas phase are continuously passed together in descending parallel flows through the hydrogenation catalyst fixed in the reactor; and at least one cooling mean for cooling the reaction system is provided at a position in the vertical direction of the reactor. According to the process of the present invention with the use of a fixed bed reactor, an alcohol, which has extremely high qualities and a high purity and is contaminated with little hydrocarbon and aldehyde by-products, can be produced. The process of the present invention further makes it possible to omit the post-treatment for eliminating the by-products. |
