Sieghard E. Wanke has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6750303
    Abstract: Functional polymers containing hydroxyl groups as supports for use with catalysts can increase the activity of these catalysts which results in improved ethylene polymerization. The present invention seeks to provide catalysts with improved activity by incorporating 2-hydroxyethyl methacrylate (HEMA) into the support of the catalyst.
    Type: Grant
    Filed: April 30, 2003
    Date of Patent: June 15, 2004
    Assignee: The Governors of the University of Alberta
    Inventors: Peter Phung Minh Hoang, Charles Russell, Jason Roy Kearns, Sieghard E. Wanke, David T. Lynch, Nai-Hong Li

  • Patent number: 4536488
    Abstract: A crystalline, silica platinum catalyst structure is provided by soaking a hydrophobic, high surface area, crystalline silica (SiO.sub.2) lattice essentially free of aluminum oxide in the SiO.sub.2 lattice, such as silicalite in an aqueous solution of Pt(NH.sub.3).sub.4 Cl.sub.2 and then, drying, reducing and cooling the crystalline silica to leave, catalyst crystallites of platinum on the crystalline silica and in the pores thereof, and then providing an outer, porous, membrane coating of high molecular weight, organic polytetrafluoroethylene, polymeric material on the coated crystallites. The platinized, crystalline silica may be slurried with, polytetrafluoroethylene and a ceramic support coated with the slurry, so that a water repellent, water vapor and hydrogen or oxygen gas permeable, polytetrafluoroethylene matrix is provided on the support with the platinized, crystalline silica dispersed in the matrix.
