  • Porous clay heterostructures prepared by gallery templated synthesis
    Patent number: 5834391
    Abstract: A porous clay heterostructure of a 2:1 layered silicate prepared by a gallery templated synthesis method is described. The method uses an inorganic oxide, a neutral amine surf surfactant and a quaternary onium ion surfactant in the galleries of the 2:1 layered silicate. The structure is then calcined to remove the surfactants which act as a template to produce the porous clay heterostructure. The structure is useful for cracking catalysts, molecular sieves and adsorbents.
    Type: Grant
    Filed: December 5, 1997
    Date of Patent: November 10, 1998
    Assignee: Board of Trustees operating Michigan State University
    Inventors: Thomas J. Pinnavaia, Anne H. Galarneau, Anis F. Barodawalla
