Samuel A. Sefa 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).

  • OLEFIN AND AROMATICS PRODUCTION BY THE CATALYTIC PYROLYSIS OF POLYMERS
    Publication number: 20250101315
    Abstract: The invention comprises methods of catalytically pyrolyzing plastics. Since it has been discovered that plastics provide insufficient coke to provide adequate heat during catalyst regeneration, heat-forming additives can be introduced into the methods. Systems and compositions useful in the catalytic pyrolysis of plastics are also described.
    Type: Application
