  • Delaminated layered zeolite precursors and method of preparing same without sonication
    Patent number: 11389788
    Abstract: Provided is a scalable delamination of a SSZ-70 framework zeolite, without the need for sonication, which has been previously made difficult by the charged nature of the imidazolium structure-directing agents that are required for zeolite synthesis. The method comprises contacting a B-SSZ-70 zeolite precursor with a zinc source such as zinc nitrate and a fluoride source.
    Type: Grant
    Filed: February 14, 2019
    Date of Patent: July 19, 2022
    Assignees: Chevron U.S.A. Inc., The Regents of the University of California
