Abstract
An extruded copper chromite-alumina catalyst is prepared by blending together from 40-82% by weight of copper chromite and 18-60% of an extrudable alumina, typically having a pseudoboehmite or .alpha. hydroxy boehmite structure. The extruded catalyst after calcining is useful for the liquid and vapor phase hydrogenation and hydrogenolysis of various carbonyl compounds and the functional side groups of aromatic compounds. The extruded catalyst is characterized as having a surface area of between 20 and 225 square meters per gram and a packed apparent bulk density of between about 0.70 and about 1.20 g/cc.
