  • Catalytic remedy for advanced UCO bleed reduction in recycle hydrocracking operations
    Patent number: 11041128
    Abstract: A catalyst system has been designed that disrupts the sedimentation process. The catalyst system achieves this by saturating key feed components before the feed components are stripped into their incompatible aromatic cores. The efficacy of this disruptive catalyst system is particularly evident in a hydrocracker configuration that runs in two-stage-recycle operation. The catalyst is a self-supported multi-metallic catalyst prepared from a precursor in the hydroxide form, and the catalyst must be toward the top level of the second stage of the two-stage system.
    Type: Grant
    Filed: August 6, 2019
    Date of Patent: June 22, 2021
    Assignee: Chevron U.S.A. Inc.
