METHOD FOR PREPARING A CATALYST

Document Type and Number:

WIPO Patent Application WO/2010/030037

Kind Code:

A1

Abstract:

Provided are a method for preparing a high-activity copper-containing hydrogenation catalyst for carrying out liquid-phase reduction without a reduction in the solvent purity, and an effective method for producing alcohol. The method for preparing the copper-containing hydrogenation catalyst is carried out by supplying hydrogen gas, or a gaseous mixture of hydrogen gas and inert gas, in the presence of a solvent and reducing a copper-containing hydrogenation catalyst precursor molding at a temperature of from 50 to 150°C in such a way that the mean reduction rate of the copper-containing hydrogenation catalyst is no more than 3.0 wt%/hour. In the method for producing alcohol a copper-containing hydrogenation catalyst is prepared in the manner described above and then an organic carboxylic acid or organic carboxylic acid ester is catalytically reduced with hydrogen in the presence of the copper-containing hydrogenation catalyst obtained.
