  • Rare earth silicate molecular sieves
    Patent number: 6761875
    Abstract: Rare earth silicate octahedral/tetrahedral molecular sieves with the octahedral chains as rare earth centers exhibit enhanced thermal and hydrothermal stability.
    Type: Grant
    Filed: September 5, 2001
    Date of Patent: July 13, 2004
    Assignee: Engelhard Corporation
    Inventors: Steven M. Kuznicki, Richard M. Jacubinas
  • Polymorph-enriched ETS-4
    Publication number: 20030068270
    Abstract: ETS-4 crystalline titanium silicate is produced so as to be enriched in at least one polymorph thereof which contains channels which interpenetrate the crystal lattice in both the b- and c-directions. A process of producing such a polymorph and enriched ETS-4 titanium silicate comprises the addition of a wetting agent to the reaction mixture.
    Type: Application
    Filed: September 4, 2002
    Publication date: April 10, 2003
    Inventors: Steven M. Kuznicki, Richard M. Jacubinas, Tadeuz W. Langner

  • Simplified methods of manufacturing titanium silicate membranes
    Patent number: 6486086
    Abstract: A simplified method of forming a porous crystalline titanium silicate membrane comprises preforming a mass of titanium dioxide particles into a consolidated preform such as by pressing into a thin film, and contacting the thin film of titanium dioxide with an aqueous alkaline silicate synthesis solution at a temperature and for a period of time sufficient to form the titanium silicate in-situ.
    Type: Grant
