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°to 140°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°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°to 250°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.

A method for preparing a copper-containing hydrogenation reaction catalyst by reducing a formed precursor of a copper-containing hydrogenation reaction catalyst with hydrogen gas or a mixture or hydrogen and inert gas by liquid phase reduction in a stream of a solvent which does not react with copper oxide or metallic copper, which comprises the steps of performing the first stage of liquid phase reduction by which the catalyst precursor is activated in the temperature range of from 20°to 140°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°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°to 250°C. A method for producing an alcohol, comprising the steps of: (a) reducing a formed precursor of a copper-containing hydrogenation reaction catalyst in a fixed bed continuous reactor with hydrogen gas or a mixture of hydrogen and inert gas by liquid phase reduction in a stream of a solvent which does not react with copper oxide or metallic copper, so as to obtain a catalyst, which comprises the steps of performing the first stage of liquid phase reduction by which the catalyst precursor is activated in the temperature range of from 20°to 140°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°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°to 250°C.; and (b) subsequently, reducing an organic carboxylic acid or ester of organic carboxylic acid by catalytic reduction with hydrogen in said fixed bed continuous reactor, using the catalyst activated in the step (a).
