Abstract

Catalyst in the form of an extrudate which comprises from 5 to 85% by weight of copper oxide and in which the same oxidic support material is present in the active composition and as binder, and the use of the catalyst for the hydrogenation of carbonyl compounds.

Claims

1. 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.

2. The process according to claim 1, wherein the oxidic support material is aluminum oxide, titanium oxide, zirconium oxide, silicon oxide, manganese oxide or a mixture thereof.

3. The process according to claim 1, wherein the oxidic support material is Al₂O₃.

4. The process according to claim 3, wherein the Al₂O₃ is predominantly present as X-ray-amorphous material.

5. The process according to claim 1, in which the shaped body catalyst is an extrudate.

11. The process according to claim 1, wherein the active component additionally includes aluminum oxide and the oxidic support material additionally includes aluminum oxide.

13. The process according to claim 1, wherein the shaped body has a pore volume of >

0.30 ml/g in the pore diameter range from 10 nm to 100 nm.

6. 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.

7. The process according to claim 6, wherein the oxidic support material is aluminum oxide, titanium oxide, zirconium oxide, silicon oxide, manganese oxide or a mixture thereof.
