  • MIDDLE DISTILLATE HYDROCRACKING CATALYST MANUFACTURED USING A HIGH NANOPORE VOLUME AMORPHOUS SILICA-ALUMINA SUPPORT
    Publication number: 20150306584
    Abstract: The present invention is directed to an improved hydrocracking catalyst containing a amorphous silica-alumina (ASA) base and alumina support. The ASA base is characterized as having a high nanopore volume and low particle density. The alumina support is characterized as having a high total nanopore volume. Hydrocracking catalysts employing the combination high nanopore volume ASA base and alumina support exhibit improved hydrogen efficiency, and greater product yield and quality, as compared to hydrocracking catalysts containing conventional ASA base and alumina components.
    Type: Application
    Filed: April 24, 2014
    Publication date: October 29, 2015
    Applicant: CHEVRON U.S.A. INC.
    Inventors: Yihua Zhang, Theodorus Ludovicus Michael Maeson
