Abstract

The present invention provides a method for simultaneous production of components suitable for production of base oil and fuel components. In the method a feedstock comprising fatty acids and/or fatty acid esters is entered into a reaction zone and subjected to a ketonization reaction in the presence of a dual catalyst system. This system is configured to perform a ketonization reaction and a hydrotreatment reaction, under hydrogen pressure. Subsequently ketones are obtained.

First claim

The invention claimed is:

1. A dual catalyst system configured to perform a ketonisation reaction and a hydrotreatment reaction simultaneously, the dual catalyst system comprising:
a metal oxide ketonisation catalyst in which the metal is selected from the group consisting of Na, Mg, K, Ca, Sc, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Ti, Y, Zr, Mo, Rh, Cd, Sn, La, Pb, Bi, Ti, V and other rare earth metals and any combination thereof; and
a metal hydrotreatment catalyst wherein the metal is selected from the group consisting of Fe, Pd, Pt, Ni, Mo, Co, Ru, Rh, W and any combination thereof;
wherein the metal oxide ketonisation catalyst and the metal hydrotreatment catalyst are combined in a single catalyst material.

2. The dual catalyst system according to claim 1 , wherein said dual catalyst system comprises a mixture or combination of a ketonisation catalyst and a hydrotreatment catalyst.

3. The dual catalyst system according to claim 2 , wherein said dual catalyst system contains 40-90% by weight of said ketonisation catalyst.

4. The dual catalyst system according to claim 1 , wherein said ketonisation catalyst is a metal oxide catalyst, in which the metal is selected from the group consisting of K, Ti, and a combination thereof.

5. The dual catalyst system according to claim 1 , herein the dual catalyst system is supported on a solid support.

6. The dual catalyst system according to claim 1 , wherein said dual catalyst system comprises NiMo and K 2 O/TiO 2 on a support.

7. The dual catalyst system according to claim 1 , wherein said dual catalyst system comprises a sulfided hydrotreatment and/or ketonisation catalyst.

8. The dual catalyst system according to claim 2 , wherein said dual catalyst system contains 70-90% by weight of said ketonisation catalyst.

9. The dual catalyst system according to claim 1 , wherein the dual catalyst system is supported on silica.

10. The dual catalyst system according to claim 1 , wherein the dual catalyst system is supported on silica.

11. The dual catalyst system according to claim 1 , wherein the dual catalyst system is supported on active carbon.
