Sam Karavolis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Steam reforming catalyst
    Patent number: 4755498
    Abstract: High activity sulfur tolerant steam reforming catalysts are described comprising iridium, palladium or platinum supported on lanthanum stabilized alumina or magnesium promoted lanthanum stabilized alumina. The catalysts have improved activity over conventionally used catalysts in the presence of sulfur containing hydrocarbon fuels, particularly in a steam reforming environment. The catalysts have utility in autothermal, tubular, cyclic and adiabatic steam reforming processes.
    Type: Grant
    Filed: September 16, 1987
    Date of Patent: July 5, 1988
    Assignee: International Fuel Cells Corporation
    Inventors: Herbert J. Setzer, Sam Karavolis, John A. S. Bett

  • Autothermal reforming catalyst and process
    Patent number: 4473543
    Abstract: High activity steam reforming catalysts are described particularly adapted for use in autothermal reforming processes. A rhodium catalyst on a calcium oxide impregnated alumina substrate allow the autothermal reforming process to take place with substantially no carbon plugging at oxygen to carbon ratios below what had been considered critical for avoiding carbon plugging of the catalyst in the past.
