Abstract

A catalyst includes a mixed metal oxide; an alumina; silica, and calcium, where the mixed metal oxide includes Cu and at least one of Mn, Zn, Ni, or Co. Such catalysts exhibit enhanced tolerance sulfur-containing compounds and free fatty acids.

First claim

What is claimed is:

1. A catalyst comprising:
a mixed metal oxide comprising Cu and at least one of Mn, Zn, Ni, or Co;
an alumina;
silica; and
calcium;
wherein the catalyst comprises a surface, wherein the percent of Cu at the surface in relation to total Cu content of the catalyst is from about 0.5% to about 20%.

2. The catalyst of claim 1 , wherein the catalyst comprises about 15 wt % to about 50 wt % Cu.

3. The catalyst of claim 1 , wherein the mixed metal oxide comprises Cu and Mn.

4. The catalyst of claim 3 , wherein the mixed metal oxide comprises Cu and Mn, and the catalyst comprises about 2 wt % to about 10 wt % Mn.

5. The catalyst of claim 3 , wherein the mixed metal oxide comprises Cu and Zn, and the catalyst comprises about 15 wt % to about 50 wt % Zn.

6. The catalyst of claim 1 , wherein the alumina is present in the catalyst at about 10 wt % to about 30 wt %.

7. The catalyst of claim 1 , wherein the silica is present in the catalyst at about 10 wt % to about 30 wt %.

8. The catalyst of claim 1 , wherein the calcium is present in the catalyst at about 2 wt % to about 10 wt %.

9. The catalyst of claim 1 , wherein the catalyst is substantially free of sodium, chromium, barium, or a combination of two or more thereof.

10. The catalyst of claim 1 , wherein the catalyst has a Brunauer-Emmett-Teller surface area from about 10 m 2 /g to about 150 m 2 /g.

11. The catalyst of claim 1 , wherein the catalyst has a mercury pore volume from about 0.10 cm 3 /g to about 0.80 cm 3 /g.

12. The catalyst of claim 1 , wherein the catalyst has a packed ambient bulk density from about 0.3 g/cm 3 to about 1.6 g/cm 3 .

13. The catalyst of claim 1 , wherein the catalyst has a side crush strength from about 2.5 lbs/mm to about 12 lbs/mm.

14. The catalyst of claim 1 , wherein the catalyst is a particulate catalyst, with the particles having an average diameter from about 0.5 mm to about 3.0 mm.

15. A method of making the catalyst of claim 1 , the method comprising calcining a shaped material;
wherein:
the shaped material is formed by shaping a paste, the paste comprising:
a Cu oxide and at least one metal oxide of Mn, Zn, Ni, or Co;
an alumina;
a silica sol; and
calcium hydroxide.

16. The method of claim 15 , wherein the calcining comprises a temperature from about 300° C. to about 1,000° C.

17. A process comprising
hydrogenation and/or hydrogenolysis of a feedstock by contacting the feedstock and H 2 with the catalyst of claim 1 ,
wherein the feedstock comprises at least one carbonyl group.

18. The process of claim 17 , wherein the process comprises hydrogenolysis of the feedstock.

19. The process of claim 17 , wherein the feedstock comprises compounds where the longest carbon chain has a carbon number from C 8 -C 18 .

20. The process of claim 17 , wherein the feedstock comprises fatty acid methyl esters.
