Abstract

A system and method for preparing and using a metal precursor diluent composition are described. The composition includes a metal precursor, and about 18% to about 80% by weight of an olefinic diluent having between 6 and 18 carbon atoms. Such compositions may be used in oligomerization catalyst systems.

First claim

What is claimed is:

1. A composition comprising:
a) a chromium catalyst precursor, and
b) about 10% to about 95% by weight of an olefinic diluent having between 6 and 18 carbon atoms, wherein the composition does not comprise a metal alkyl compound.

2. The composition of claim 1 , wherein the composition comprises a nitrogen containing compound.

3. The composition of claim 1 , wherein the composition comprises from about 18% to about 80% by weight of the olefinic diluent.

4. The composition of claim 1 , wherein the composition comprises from about 25% to about 55% by weight of the olefinic diluent.

5. The composition of claim 1 , wherein the chromium catalyst precursor is a chromium (II) or chromium (III) organometallic compound.

6. The composition of claim 1 , wherein the chromium catalyst precursor is a chromium (II) or chromium (III) acetonate or carboxylate.

7. The composition of claim 1 , wherein the chromium catalyst precursor is a chromium (II) or chromium (III) carboxylate wherein each carboxylate is a C 4 to C 19 carboxylate.

8. The composition of claim 1 , wherein the chromium catalyst precursor is chromium (III)2 -ethylhexanoate.

9. The composition of claim 1 , wherein the olefinic diluent is an alpha olefin.

10. The composition of claim 1 , wherein the olefinic diluent is selected from the group consisting of 1-decene, 1-dodecene, 1-tetradecene, and mixtures thereof.

11. The composition of claim 1 , wherein the olefinic diluent is 1-decene or 1-dodecene.

12. The composition of claim 1 , wherein the chromium catalyst precursor is a chromium(III) carboxylate wherein each carboxylate is a C 4 to C 19 carboxylate, the olefinic diluent consists essentially of a C 10 to C 14 normal alpha olefin, and the composition comprises from 25% to 55% of the olefinic diluent.

13. An oligomerization catalyst system comprising the composition of claim 1 .

14. An oligomerization catalyst system comprising the composition of claim 12 .

15. A composition comprising: a) a chromium catalyst precursor;
and b) an olefinic diluent having between 6 and 18 carbon atoms, wherein the weight ratio of diluent to the chromium atom in the precursor ranges from 13:1 to 44:1, and wherein the composition does not comprise a metal alkyl compound.

16. The composition of claim 15 , wherein the composition comprises a nitrogen containing compound.

17. The composition of claim 15 , wherein the weight ratio of the olefinic diluent to the chromium atom ranges from 16:1 to 28:1.

18. The composition of claim 15 , wherein the chromium catalyst precursor is a chromium (II) or chromium (III) organometallic compound.

19. The composition of claim 15 , wherein the chromium catalyst precursor is a chromium (II) or chromium (III) acetonate or carboxylate.

20. The composition of claim 15 , wherein the chromium catalyst precursor is a chromium (II) or chromium (III) carboxylate wherein each carboxylate is a C 4 to C 19 carboxylate.

21. The composition of claim 15 , wherein the chromium catalyst precursor is chromium (III) 2-ethylhexanoate.

22. The composition of claim 15 , wherein the olefinic diluent is an alpha olefin.

23. The composition of claim 15 , wherein the olefinic diluent is selected from the group consisting of 1-decene, 1-dodecene, 1-tetradecene, and mixtures thereof.

24. The composition of claim 15 , wherein the olefinic diluent is 1-decene or 1-dodecene.

25. The composition of claim 15 , wherein the chromium catalyst precursor is a chromium(III) carboxylate wherein each carboxylate is a C 4 to C 19 carboxylate, the olefinic diluent consists essentially of a C 10 to C 14 normal alpha olefin, and the weight ratio of the olefinic diluent to the chromium atom ranges from 16:1 to 28:1.

26. An oligomerization catalyst system comprising the composition of claim 15 .

27. An oligomerization catalyst system comprising the composition of claim 25 .
