1. A shaped catalyst body having a macroscopically uniform structure and comprising:
- from 5 to 85% by weight of copper oxide as an active component andAl2O3 as oxidic support material and as binder, whereina) the shaped catalyst body has a pore volume of greater than 0.15 ml/g in the pore diameter range from 10 nm to 100 nm, andb) the oxidic support material in the shaped body is present both in finely disperse form and also to a proportion by volume of from 1 to 95% by volume of the shaped body in particulate form and is predominantly present as X-ray-amorphous material.

Abstract
The invention relates to a catalyst provided in the form of an extrudate, which contains 5 to 85% by weight of copper oxide and comprises, in the active material and as binders, the same oxidic carrier material. The invention also relates to the use of the catalyst for hydrogenating carbonyl compounds.
