摘要： A method for preparing a copper-containing hydrogenation reaction catalyst includes the step of reducing a formed precursor of a copper-containing hydrogenation reaction catalyst with hydrogen gas or a mixture of hydrogen and inert gas by liquid phase reduction in a stream of a solvent. The reductive activation is carried out by the two steps of performing the first stage of liquid phase reduction by which the catalyst precursor is activated in the temperature range of from 20.degree. to 140.degree. C. so that at least 10% by weight of the copper oxide contained in the catalyst precursor can be reduced by the time when the temperature passes 140.degree. C., and then performing the second stage of liquid phase reduction by which the catalyst precursor is further activated in the temperature range of from 140.degree. to 250.degree. C. The catalyst thus obtained has markedly improved catalytic activity and selectivity. An alcohol of high quality can be obtained at a high productivity using the catalyst in a fixed bed continuous reaction system.

摘要： There is provided a process wherein a lower alkyl ester of a fatty acid derived from natural fats and oils and a lower alcohol containing 1 to 4 carbon atoms is produced in a lower sulfur content at lower costs without causing a reduction in yield and a deterioration in selectivity, as well as a process for producing an alcohol without reducing the activity of a catalyst. The process comprises the step of adsorption treatment of an ester with at least one adsorbent selected from clay and activated carbon. Further are provided a process for producing an ester which further comprises adsorption treatment with a hydrogenating decomposition-type adsorbent containing Ni and/or Cu, in hydrogen or a mixed gas atmosphere of hydrogen and an inert gas, and a process for producing an alcohol which comprises hydrogenation reaction with an ester produced by any one of these processes as the starting material.
