  • Asphaltene hydrodesulfurization with small catalyst particles in a parallel reactor system
    Patent number: RE29314
    Abstract: The hydrodesulfurization of a crude oil or a reduced crude containing the asphaltene fraction proceeds at unexpectedly low temperatures by utilizing a Group VI and Group VIII metal containing catalyst on alumina when the catalyst particles are very small and have a diameter between about 1/20 and 1/40 inch and are disposed in a parallel catalyst bed system.
    Type: Grant
    Filed: September 8, 1976
    Date of Patent: July 19, 1977
    Assignee: Gulf Research & Development Company
    Inventors: Edgar Carlson, deceased, BY Gulf Research & Development Company, Alfred M. Henke, William R. Lehrian, Joel D. McKinney, Kirk J. Metzger
  • Asphaltene hydrodesulfurization with small catalyst particles utilizing a hydrogen quench for the reaction
    Patent number: RE29315
    Abstract: The hydrodesulfurization of a crude oil or a reduced crude containing the asphaltene fraction proceeds at unexpectedly low temperatures by utilizing a catalyst comprising a Group VI and Group VIII metal on alumina when the catalyst particles are very small and have a diameter between about 1/20 and 1/10 inch and the reaction is quenched with hydrogen.
