  • Interzeolite transformation and metal encapsulation in the absence of an SDA
    Patent number: 9938157
    Abstract: Provided is a method of encapsulating a metal in a zeolite. The method comprises inserting a metal precursor into a parent zeolite, and then converting the parent zeolite to a zeolite having a higher framework density than the parent zeolite. The conversion is achieved without the need of an organic structure directing agent.
    Type: Grant
    Filed: May 11, 2015
    Date of Patent: April 10, 2018
    Assignees: Chevron U.S.A. Inc., The Regents of the University of California
    Inventors: Sarika Goel, Stacey Ian Zones, Enrique Iglesia
  • Synthesis of high silica zeolite via interzeolite transformation without OSDAs
    Patent number: 9802831
    Abstract: Provided is a method for preparing a zeolite having a Si/Al ratio of at least 10 by interzeolite transformation in the absence of an organic structure directing agent. The method is more cost effective and less equipment intensive as it eliminates the costly organic structure directing agent and the waste treatment at the plant.
