  • Methods of Preparation of an Olefin Oligomerization Catalyst
    Publication number: 20080058534
    Abstract: A method of making a catalyst for use in oligomerizing an olefin comprising a chromium-containing compound, a pyrrole-containing compound, a metal alkyl, a halide-containing compound, and optionally a solvent, the method comprising contacting a composition comprising the chromium-containing compound and a composition comprising the metal alkyl, wherein the composition comprising the chromium-containing compound is added to the composition comprising the metal alkyl.

  • Methods of preparation of an olefin oligomerization catalyst
    Publication number: 20070043181
    Abstract: A method of making an olefin oligomerization catalyst, comprising contacting a chromium-containing compound, a heteroatomic ligand, and a metal alkyl, wherein the chromium-containing compound comprises less than about 5 weight percent chromium oligomers. A method of making an olefin oligomerization catalyst comprising a chromium-containing compound, a nitrogen-containing compound, and a metal alkyl, the method comprising adding a composition comprising the chromium-containing compound to a composition comprising the metal alkyl. A method of making an olefin oligomerization catalyst comprising a chromium-containing compound, a nitrogen-containing compound, and a metal alkyl, the method comprising abating all or a portion of water, acidic protons, or both from a composition comprising the chromium-containing compound, a composition comprising the nitrogen-containing compound, or combinations thereof prior to or during the preparation of the catalyst.
