Abstract

A copper oxide/zinc oxide/aluminium oxide catalyst which contains, per 100 parts of copper oxide, 40 to 130 parts zinc oxide, 2 to 50 parts aluminium oxide, and 1 to 4 parts soium oxide. It has a total BET surface area of 50 to 100 m.sup.2 /g, and 75% to 95% of the total surface area is made up by pores having radii of 9 to 1000 nm, and 5% to 25% of the total surface area is made up by pores having radii of less than 9 nm. The catalyst is useful for hydrogenation of various organic compounds.
