Abstract

The present application relates to method for oligomerizing olefin or for producing polyalphaolefin utilizing catalyst mixtures comprising aluminum halides and an organic liquid carrier. A process comprising contacting 1) a catalyst mixture comprising i) an aluminum trihalide and ii) an organic liquid carrier comprising first olefins, wherein the organic liquid carrier first olefins comprise at least 60 mole % 1,2-disubstituted olefins, trisubstituted olefins, or any combination thereof; and 2) a monomer comprising second olefins to form an oligomer product. An oligomer product produced by the process comprising contacting 1) a catalyst mixture comprising i) an aluminum trihalide and ii) an organic liquid carrier comprising first olefins, wherein the organic liquid carrier olefins comprise at least 75 mole % 1,2-disubstituted olefins, trisubstituted olefins, or any combination thereof; and 2) a monomer comprising second olefins to form an oligomer product.

First claim

What is claimed is:

1. A process comprising:
contacting
1) a catalyst mixture comprising i) an aluminum trihalide and ii) an organic liquid carrier comprising first olefins, wherein the organic liquid carrier first olefins comprise at least 60 mole % 1,2-disubstituted olefins; and
2) a monomer comprising second olefins
to form an oligomer product.

2. The process of claim 1 , wherein the organic liquid carrier first olefins comprise less than 5 mole % alpha olefins.

3. The process of claim 1 , wherein the organic liquid carrier first olefins comprise less than 20 mole % tetrasubstituted olefins, vinylidenes, or any combinations thereof.

4. The process of claim 1 , wherein the organic liquid carrier first olefins comprise at least 75 mole % 1,2-disubstituted olefins, wherein the 1,2-disubstituted olefins comprise C 6 to C 24 disubstituted olefins.

5. The process of claim 1 , wherein the aluminum trihalide comprises aluminum trichloride, aluminum tribromide, or any combination thereof.

6. The process of claim 1 , wherein the catalyst mixture has an aluminum trihalide to organic liquid carrier first olefins molal concentration ranging from 0.15 mole/kg to 4.0 mole/kg.

7. The process of claim 1 , wherein the catalyst mixture further comprises a promoter.

8. The process of claim 1 , wherein the catalyst mixture, the monomer, and a promoter are contacted to form an oligomer product.

9. The process of claim 7 , wherein the promoter comprises water, an alcohol, a carboxylic acid, an ester, a ketone, an ether, a halogenated hydrocarbon, or any combination thereof.

10. The process of claim 1 , wherein the catalyst mixture further comprises a metal halide, an alkyl metal halide, an alkyl metal compound, or any combination thereof or wherein the catalyst mixture, the monomer, and a metal halide, an alkyl metal halide, an alkyl metal compound, or any combination thereof are contacted to form the oligomer product; and wherein the metal halide and the aluminum trihalide are different.

11. The process of claim 1 , wherein the aluminum trihalide and the monomer are contacted at a molar ratio ranging from 5×10 −8 :1 to 1.1×10 −2 :1.

12. The process of claim 1 , wherein the monomer comprises C 3 to C 30 olefins.

13. The process of claim 1 , wherein the monomer comprises alpha olefins.

14. The process of claim 1 , wherein the monomer comprises 1-hexene, 1-octene, 1-decene, 1-dodecene, 1-tetradecene, or any combination thereof.

15. The process of claim 1 , wherein the monomer comprises at least 50 mole % normal alpha olefins.

16. The process of claim 1 , wherein the oligomer product is formed under oligomerization conditions comprising a temperature ranging from 0° C. to 200° C.

17. The process of claim 1 , wherein the oligomer product is formed under oligomerization conditions comprising a substantial absence of an organic solvent.

18. The process of claim 1 , wherein at least 50 mole % of the monomer is converted to the oligomer product.

19. The process of claim 1 , further comprising contacting a reactor effluent with a catalyst deactivating agent.

20. The process of claim 1 , further comprising separating at least a portion of the oligomer product from the monomer, to yield a separated oligomer product.

21. The process of claim 20 , further comprising hydrogenating the separated oligomer product to form a polyalphaolefin.
