Abstract

A catalyst is provided for hydrodeoxygenation and hydroisomerization of paraffins having higher activity. The catalyst contains a molecular sieve, such as SAPO-11, a metal component such as platinum and/or palladium or nickel tungsten sulfide or nickel molybdenum sulfide and a binder such as gamma alumina. The catalyst exhibits a high proportion of weak acid sites and a relatively equal distribution of the metal component on the molecular sieve and the binder.

First claim

The invention claimed is:

1. A catalytically active material comprising a metal component, and comprising as a support at least a molecular sieve, a metal oxide, and a carbon material, wherein about 40-60% of said metal component is dispersed on said molecular sieve and about 40-60% of said metal component is dispersed on said metal oxide, and wherein 25 wppm-1000 wppm carbon as carbon material is in the support, excluding the supported active metal components.

2. The catalytically active material of claim 1 wherein 25-500 wppm carbon as carbon material is in the support, excluding the supported active metal components.

3. The catalytically active material according to claim 1 wherein the metal component is selected from platinum, palladium, nickel, combinations of platinum and/or palladium, and/or nickel, nickel molybdenum sulfide or nickel tungsten sulfide.

4. The catalytically active material according to claim 1 wherein the metal component is selected from platinum or nickel tungsten sulfide.

5. The catalytically active material according to claim 1 wherein about 50% of the metal component is dispersed on said molecular sieve and about 50% of the metal component is dispersed on the metal oxide.

6. The precursor for a catalytically active material or a catalytically active material according to claim 1 , wherein said metal oxide is taken from the group comprising alumina, silica, silica-alumina and titania.

7. The catalytically active material according to claim 1 , wherein said metal oxide is alumina.

8. The catalytically active material according to claim 1 , wherein said metal oxide is gamma alumina.

9. The catalytically active material according to claim 1 , wherein said molecular sieve has the AEL framework type.

10. The catalytically active material according to claim 1 , wherein said molecular sieve is SAPO-11.

11. The catalytically active material of claim 10 wherein at least 50% of acid sites on said SAPO-11 are weak acid sites.

12. The catalytically active material of claim 10 wherein at least 60-80% of external acid sites on said SAPO-11 are weak acid sites.

13. A process for dewaxing a hydrocarbon or a hydrocarbon mixture involving contacting said hydrocarbon or hydrocarbon mixture with a catalytically active material comprising a metal component, and comprising as a support at least a molecular sieve, a metal oxide, and a carbon material, wherein about 40-60% of said metal component is dispersed on said molecular sieve and about 40-60% of said metal component is dispersed on said metal oxide, and wherein 25 wppm-1000 wppm carbon as carbon material is in the support, excluding the supported active metal components in the presence of hydrogen under dewaxing conditions.

14. The process of claim 13 wherein 25-500 wppm carbon as carbon material is in the support, excluding the supported active metal components.

15. The process according to claim 13 wherein the metal component is selected from platinum, palladium, nickel, combinations of platinum, and/or palladium, and/or nickel, nickel molybdenum sulfide or nickel tungsten sulfide.

16. The process according to claim 13 wherein the metal component is selected from platinum or nickel tungsten sulfide.

17. The process according to claim 13 wherein about 50% of the metal component is dispersed on said molecular sieve and about 50% of the metal component is dispersed on the metal oxide.

18. The process according to claim 13 , wherein said molecular sieve is SAPO-11.

19. The process according to claim 13 , wherein said metal oxide is alumina.

20. The process according to claim 13 , wherein said metal oxide is gamma alumina.
