  • Ethylene oligomerization catalyst systems using chemically-treated solid oxides
    Patent number: 9968921
    Abstract: Disclosed herein are catalyst compositions containing a heteroatomic ligand transition metal compound complex, a chemically-treated solid oxide, and an organoaluminum compound. These catalyst compositions can be used in an ethylene oligomerization process to produce a liquid oligomer product containing hexene and octene, as well as a solid polymer product with a molecular weight sufficiently high to permit easy separation of the liquid oligomer product from the solid polymer product.
    Type: Grant
    Filed: June 9, 2017
    Date of Patent: May 15, 2018
    Assignee: Chevron Phillips Chemical Company LP
    Inventors: Uriah J. Kilgore, Steven R. Hutchison, Orson L. Sydora, Steven M. Bischof, Jared T. Fern, Max P. McDaniel
