  • Synthesis and use of nanocrystalline zeolites
    Patent number: 7858062
    Abstract: Embodiments of the present invention relate to a method for synthesizing nanocrystalline zeolites, the method comprising contacting starting products that comprise a solvent, a silicon source, a cation base, an organic template, and an aluminum source, or any combination thereof sufficient to produce a zeolite gel by hydrolysis, heating the zeolite gel sufficient to produce a first batch of zeolite crystals and a first clear solution, separating the first batch of zeolite crystals from the first clear solution, heating the first clear solution sufficient to produce a second batch of zeolite crystals and second clear solution and separating the second batch of zeolite crystals from the second clear solution.
    Type: Grant
    Filed: July 28, 2009
    Date of Patent: December 28, 2010
    Assignee: University of Iowa Research Foundation
    Inventors: Sarah Larsen, Vicki Grassian, Weiguo Song, Gonghu Li
