Natasha Erdman 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).

  • Enhancement of molecular sieve performance
    Patent number: 7977273
    Abstract: A catalyst for converting methanol to light olefins and the process for making and using the catalyst are disclosed and claimed. SAPO-34 is a specific catalyst that benefits from its preparation in accordance with this invention. A seed material is used in making the catalyst that has a higher content of the EL metal than is found in the principal part of the catalyst. The molecular sieve has predominantly a roughly rectangular parallelepiped morphology crystal structure with a lower fault density and a better selectivity for light olefins.
    Type: Grant
    Filed: April 28, 2009
    Date of Patent: July 12, 2011
    Assignee: UOP LLC
    Inventors: Wharton Sinkler, Robert W. Broach, Natasha Erdman, Thomas M. Reynolds, John Q. Chen, Stephen T. Wilson, Paul T. Barger
