A process for hydrogenation of carbonyl compounds comprising hydrogenating a carbonyl compound in the presence of a shaped catalyst body having a macroscopically uniform structure and comprising from 5 to 85% by weight of copper oxide as an active component and an oxidic support material, wherein
- a) the shaped body has a pore volume of >0.15 ml/g in the pore diameter range from 10 nm to 100 nm and
- b) 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.
A process for gas-phase hydrogenation of maleic anhydride comprising hydrogenating maleic anhydride in the presence of a shaped catalyst body having a macroscopically uniform structure and comprising from 5 to 85% by weight of copper oxide as an active component and an oxidic support material, wherein
- a) the shaped body has a pore volume of >0.15 ml/g in the pore diameter range from 10 nm to 100 nm and
- b) 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.
