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.
Claims27
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.
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.
