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: L'invention a notamment pour objet un procédé pour produire des alcools par réduction catalytique de graisses et d'huiles ou d'esters d'acides gras par l'hydrogène en présence d'un catalyseur pour la réduction des esters. Selon l'invention, lesdites graisses et huiles ou lesdits esters d'acides gras sont préalablement traités dans une atmosphère d'hydrogène ou d'un mélange d'hydrogène et d'un gaz inerte à une température de 100 à 350degré C pour donner une teneur en soufre des graisses et huiles ou des esters d'acides gras de 0,6 ppm ou moins, en présence d'un catalyseur représenté par la formule (I) suivante: (CF DESSIN DANS BOPI) dans laquelle X représente un élément choisi parmi Fe, Zn et Cr; Y représente un élément choisi parmi Al, Si et Ti; x et y représentent chacun une proportion atomique rapportée à la proportion de Cu prise égale à 1, pourvu que x ait une valeur de 0,02 à 2,4 et y une valeur de 0 à 2,0; et z est la proportion d'oxygène satisfaisant les conditions de valences des éléments représentés par X et Y. Applications: fabrication d'alcools de haute pureté avec un bon rendement par réduction.
