  • Processes for preparing solid metallocene-based catalyst systems
    Patent number: 10059783
    Abstract: Methods for preparing metallocene-based catalyst systems containing an activator-support are disclosed. These methods can include contacting a solid metallocene compound, an activator-support, and an organoaluminum compound, resulting in catalyst systems with increased catalytic activity as compared to catalyst systems utilizing a solution of the metallocene compound.
    Type: Grant
    Filed: February 1, 2017
    Date of Patent: August 28, 2018
    Assignee: Chevron Phillips Chemical Company LP
    Inventors: Kensha M. Clark, Qing Yang, Gary L. Glass
