Abstract
The present invention relates to a supported catalyst, comprising a) a support b) a metal A, being chosen from nickel and copper or a combination thereof in metallic or oxidic state c) a metal B, being chosen from lithium and calcium or a combination thereof in metallic or oxidic state with the proviso that when metal A comprises nickel, metal B is lithium. Also, the present invention relates to processes for the preparation of the supported catalyst and to the use of the supported catalyst as a hydrogenation catalyst.
Claims
1. Supported hydrogenation catalyst, in particular for nitrile to amine conversion, comprising a) a support, b) a metal A, being chosen from nickel and copper or a combination thereof in metallic or oxidic state, c) a metal B, being chosen from lithium and calcium or a combination thereof in metallic or oxidic state with the proviso that when metal A comprises nickel, metal B is lithium, wherein the supported catalyst is substantially free of other group VIII metals, the weight content of said other group VIII metals being less than 5% of the weight content of metal A.
2. Supported catalyst according to claim 1, the support comprising silica, alumina, zirconia, titania, magnesiumoxide, calcium carbonate and carbon, or a combination of at least two thereof.
3. Supported catalyst to claim 2, the porous support comprising zirconia, alumina or a combination thereof.
4. Supported catalyst according to any of the preceding claims, wherein the catalyst comprises, based on the dry weight of the catalyst, at least 1%, preferably at least 4% by weight, of metal B.
5. Supported catalyst according to claim 4, wherein the catalyst comprises, based on the dry weight of the catalyst, 4-20% by weight of metal B.
6. Supported catalyst according to any of the preceding claims, wherein the catalyst comprises 0.1-50 mmol metal per gram dry support.
7. Catalyst according to one or more of the preceding claims, wherein metal B is lithium.
8. Catalyst according to one or more of the preceding claims, wherein the catalyst comprises copper and calcium.
9. Method for the preparation of a supported catalyst, comprising the steps of a) treating a support with a solution comprising a dissolved salt of a metal B, being chosen from lithium and calcium or a combination thereof in metallic or oxidic state, b) treating the support with a solution comprising a dissolved salt of a metal A, being chosen from nickel and copper or a combination thereof in metallic or oxidic state, with the proviso that when metal A comprises nickel, metal B is lithium, c) calcining the treated support.
10. Method according to claim 9, wherein steps a) and b) are combined in that the support is treated with a solution comprising dissolved salts of both metals A and B.
11. Method according to claim 9, wherein between steps a) and b) the support is calcined.
12. Method according to claim 11, wherein the calcination is performed between 350-600°C, preferably between 500-580°C, most preferably at about 550°C.
13. Method according to any of the claims 9-12, wherein the support is dried before the calcination step.
14. Method according to claim 13, wherein drying is performed between 80-150°C, preferably between 125-145°C, most preferably at about 140°C.
AMENDED' SHEET (ARTICLE 19)
15. Method according to any of the claims 9-14, wherein the dissolved salt of at least one of the metals A and B, is a nitrate salt, preferably both being nitrate salts.
16. Method according to any of the claims 9-15, wherein the support comprises silica, alumina, zirconia, titania, magnesiumoxide, calcium carbonate and carbon, or a combination of at least two thereof.
17. Method according to any of the claims 9-16, wherein the obtained catalyst comprises, based on the dry weight of the catalyst, at least 1 w/w%, preferably at least 4 w/w%, and most preferably 4-20 w/w% of metal B.
18. Use of a catalyst according to any of the claims 1-9 for the hydrogenation of nitriles into amines.
19. Use of a catalyst obtainable by the method according to any of the claims 9-17, for the hydrogenation of nitriles into amines.
