  • Bulk group VIII/group VIB metal catalysts and method of preparing same
    Patent number: 7951746
    Abstract: Bulk metallic catalysts comprised of a Group VIII metal and a Group VIB metal and methods for synthesizing bulk metallic catalysts are provided. The catalysts are prepared by a method wherein precursors of both metals are mixed and interacted with at least one organic acid, such as glyoxylic acid, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.
    Type: Grant
    Filed: October 9, 2007
    Date of Patent: May 31, 2011
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Chuansheng Bai, El-Mekki El-Malki, Jeff Elks, Zhiguo Hou, Jon M. McConnachie, Pallassana S. Venkataraman, Jason Wu, Jun Han, Daniel Giaquinta, Alfred Hagemeyer, Valery Sokolovskii, Anthony F. Volpe, Jr., David Michael Lowe
  • High activity supported distillate hydroprocessing catalysts
    Patent number: 7615509
    Abstract: Supported metallic catalysts comprised of a Group VIII metal, a Group VIB metal, and an organic additive, and methods for synthesizing supported metallic catalysts are provided. The catalysts are prepared by a method wherein precursors of both metals are mixed and interacted with at least one organic additive, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.
