  • Hydroconversion process with plug-flow molybdenum catalyst concentrate preparation
    Patent number: 5620591
    Abstract: A hydroconversion process for converting a heavy hydrocarbonaceous feedstock to lower boiling products, which process involves the use of a sulfided catalyst concentrate which is prepared in a continuous plug-flow mode. The heavy hydrocarbonaceous feedstock is reacted with said catalyst concentrate in the presence of hydrogen at hydroconversion conditions.
    Type: Grant
    Filed: December 22, 1994
    Date of Patent: April 15, 1997
    Assignee: Exxon Research & Engineering Company
    Inventors: Martin C. Poole, Thomas R. Halbert, Roby Bearden, Stephen D. Reynolds
  • Coal liquefaction using atomically dispersed metals
    Patent number: 5454934
    Abstract: A method for converting solid carbonaceous materials to liquid products. The solid carbonaceous material is first treated with a aqueous composition of a metal carbonate or bicarbonate. This results in the metal being atomically dispersed in the carbonaceous material. The treated solid carbonaceous material is then subjected to liquefaction conditions. The preferred metal is iron.
    Type: Grant

    Date of Patent: October 3, 1995
    Assignee: Exxon Research & Engineering Co.
    Inventors: Stephen D. Reynolds, Claude C. Culross, Stephen D. LeViness, John W. Larsen
  • Method for atomically dispersing catalytic metals into support materials
    Patent number: 5378673
    Abstract: A process for the atomic dispersion of metals into support materials, preferably silica, alumina, and amorphous and zeolitic alumino-silicates. The support material is contacted with an aqueous composition of a metal carbonate, or bicarbonate. This results in the metal being atomically dispersed in the support material.
