Abstract
The present invention provides a hydrogenation catalyst precursor which does not bring about a problem of environmental pollution involved in copper-chromium catalysts and has a high activity, a high durability and a high selectivity as compared with those of conventional copper-iron-aluminum catalysts, a hydrogenation catalyst obtained by reducing the same, and a production process for alcohols using the above hydrogenation catalyst. The hydrogenation catalyst precursor described above comprises copper, iron and aluminum and containing as a principal component a compound oxide of copper, iron and aluminum in which an atomic ratio Cu:Fe:Al is 1:(0.02 to 0.4):(1.0 to 4.0) and which has a copper-aluminum spinel structure.
