Paul Stepanoff 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).

  • Production of endothermic gases with methanol
    Patent number: 4859434
    Abstract: The present invention is directed to a process for producing endothermic gases from methanol and inert gas streams containing minor amounts of oxygen, wherein the oxygen is reacted with stoichiometric excess quantities of methanol over a catalyst as ambient feed temperature conditions without a requirement for external heating of the reaction to produce an endothermic gas containing very low levels of oxygen and methanol and significant quantities of hydrogen, carbon monoxide, water and carbon dioxide.
    Type: Grant
    Filed: June 10, 1988
    Date of Patent: August 22, 1989
    Assignee: Air Products and Chemicals, Inc.
    Inventors: George W. Roberts, Shivaji Sircar, Paul Stepanoff
  • Deoxygenation of inert gas streams with methanol
    Patent number: 4859435
    Abstract: The present invention is directed to a process for removing minor amounts of oxygen from inert gas streams to result in very low levels of oxygen contamination in such inert gas streams, wherein the oxygen is removed by the action of stoichiometric quantities of methanol, which react with the oxygen over a catalyst at ambient feed temperature conditions without a requirement for external heating of the reaction.
