Abstract: A process for producing an alcohol from a fatty acid ester, a fatty acid triglyceride or a fatty acid by continuously catalytically reducing the starting material in the presence of a hydrogenation catalyst is disclosed. In the process of the present invention, two reactors (i.e., the main reactor located upstream and the after reactor located downstream) being located in series are employed. In the process of the present invention, two reactors are employed and the temperatures thereof are individually controlled, whereby the conversion ratio is elevated while suppressing the formation of hydrocarbon and aldehyde by-products. Thus, an alcohol of extremely high quality and high purity can be produced. Further, the process of the present invention makes it possible to omit any post-treatment for eliminating the by-products. Furthermore, the active life of the hydrogenation catalyst can be remarkably prolonged by using three reactors (i.e., the guard reactor, the main reactor and the after reactor).

Abstract: 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.

Abstract: PURPOSE:To obtain highly activated catalyst for hydrogenation by specifying the temperature of a reactive medium when an alkali agent is added as a sedimentation agent to an aqueous water-soluble metal salt solution. CONSTITUTION:A mixture of water-soluble copper salt or a mixture of water-soluble copper salt and water-soluble zinc salt, and an alkali agent such as ammonia or urea as a sedimentation agent are allowed to undergo a chemical reaction with an aqueous medium. In this case, this sedimentation production reaction is performed at high temperatures such as 100 to 300 deg.C preferably 150 to 250 deg.C. If this protocol is performed, a catalyst obtained is highly activated, and the yield and quality of a corresponding alcohol produced by hydrogenation reaction of an organic carboxylic acid ester can be further improved.
