Abstract

The present disclosures and inventions relate to a catalyst or catalyst composition and the methods of making and using the catalyst or catalyst composition. In one aspect, the present disclosure relates to a catalyst composition that includes a catalyst having the formula C A C B O x and a catalyst support; a) C A is Co a Mn b X d , wherein X comprises Si, Ti, Cu, Zns Pd, or La or a combination thereof; a ranges from 0.8 to 1.2; b ranges from 0.1 to 1; and d ranges from 0 to 0.5; and b) C B is Ni e Cu f Mg h Si m , wherein e ranges from about 0.8 to 1.2; f ranges from 0 to 1; h ranges from 0 to 0.5; and m ranges from 0 to 0.5; wherein O x is determined by the valence requirements of the other elements present, wherein in the catalyst support consists essentially of magnesia, alumina, silica, titanic, carbon, or zeolite, or a combination thereof; and wherein the catalyst composition converts synthesis gas to at least one olefin.

First claim

What is claimed is:

1. A catalyst composition consisting essentially of a formula C A C B O x and a catalyst support; said catalyst consisting of
a. C A is Co a Mn b X d , wherein
X comprises Si, Ti, Cu, Zn, Pd, or La or a combination thereof;
a ranges from 0.8 to 1.2;
b ranges from 0.1 to 1; and
d ranges from 0 to 0.5; and

b. C B is Ni e Cu f Mg h Si m , wherein
e ranges from about 0.8 to 1.2;
f ranges from 0 to 1;
h ranges from 0 to 0.5; and
m ranges from 0 to 0.5;

wherein O x is determined by the valence requirements of the other elements present;
wherein in the catalyst support consists essentially of magnesia, alumina, silica, titania, carbon, or zeolite, or a combination thereof; and
wherein the catalyst composition converts synthesis gas to at least one olefin.

2. The catalyst composition of claim 1 , wherein f ranges from 0.1 to 1.

3. The catalyst composition of claim 2 , wherein h ranges from 0.1 to 0.5.

4. The catalyst composition of claim 3 , wherein m ranges from 0.1 to 0.5.

5. The catalyst composition of claim 4 , wherein d ranges from 0.1 to 0.5.

6. The catalyst composition of claim 1 , wherein the catalyst does not comprise an alkyl or an acyl group.

7. The catalyst composition of claim 1 , wherein the catalyst support comprises carbon comprising activated carbon or nonactivated carbon, or a combination thereof.

8. The catalyst composition of claim 1 , wherein the catalyst composition does not comprise boehmite.

9. The catalyst composition of claim 1 , wherein the catalyst composition does not comprise a polar organic solvent.

10. A method for using a catalyst composition comprising:
a. contacting the catalyst composition of claim 1 with a synthesis gas; and
b. forming a product mixture comprising at least one olefin.

11. The method of claim 10 , wherein the at least one olefin comprises carbons ranging from two carbons to 12 carbons.

12. The method of claim 10 , wherein the at least one olefin comprises ethylene, propene, 1-butene, 1-pentene, 1-hexene, 1-heptene, 2-ethyl-hexylene, 2-ethyl-heptene, 1-octene, 1-nonene, or 1-decene, or a combination thereof.

13. The method of claim 10 , wherein the product mixture comprises methane.

14. The method of claim 10 , wherein the conversion percent of synthesis gas to the product mixture ranges from 30% to 100%.

15. The method of claim 10 , wherein the product mixture comprises at least one olefin in an amount ranging from 60 wt % to 90 wt %, based on total weight of the product mixture.

16. The method of claim 10 , wherein the product mixture comprises carbon dioxide in an amount ranging from 0 wt % to 5 wt %, based on total weight of the product mixture.

17. The method of claim 10 , wherein the product mixture comprises methane in an amount ranging from 2 wt % to 20 wt %, based on total weight of the product mixture.

18. The method of claim 10 , wherein the product mixture consists essentially of carbon dioxide, methane, and one or more olefins.

19. The method of claim 10 , wherein the method comprises the further step of removing a solvent from the catalyst composition.

20. The method of claim 19 , wherein the solvent comprises water.
