  • Selective thermal and photooxidation of hydrocarbons in zeolites by oxygen
    Patent number: 6329553
    Abstract: A process for a combined selective thermal oxidation and photooxidation of hydrocarbons adsorbed onto zeolite matrices. A highly combined selective thermal oxidation and photooxidation of unsubstituted or alkyl substituted alkanes, alkenes, aromatics and cycloalkyls in solvent free zeolites under dark thermal conditions or under irradiation with visible light. The process oxidizes hydrocarbons almost completely selectively without substantial production of byproducts.
    Type: Grant
    Filed: November 10, 2000
    Date of Patent: December 11, 2001
    Assignee: The Regents of the University of California
    Inventors: Heinz Frei, Fritz Blatter, Hai Sun
  • Selective thermal oxidation of hydrocarbons in zeolites by oxygen
    Patent number: 6150562
    Abstract: A process for selective thermal oxidation of hydrocarbons adsorbed onto zeolite matrices. A highly selective thermal oxidation of unsubstituted or alkyl substituted alkanes, alkenes, aromatics and cycloalkyls is carried out in solvent free zeolites under dark thermal conditions. The process oxidizes hydrocarbons almost completely selectively without substantial production of byproducts.

  • Selective photooxidation of hydrocarbons in zeolites by oxygen
    Patent number: 5827406
    Abstract: A selective photooxidation process for the conversion of hydrocarbon molecules to partially oxygenated derivatives, which comprises the steps of adsorbing a hydrocarbon and oxygen onto a dehydrated zeolite support matrix to form a hydrocarbon-oxygen contact pair, and subsequently exposing the hydrocarbon-oxygen contact pair to visible light, thereby forming a partially oxygenated derivative.

  • Storage and transportation apparatus
    Patent number: 4191415
    Abstract: The invention relates to apparatus for storing and transporting heavy elongated workpieces such as round steel, sectional steel, steel pipes and the like. The apparatus comprises at least two stock racks each of which is formed from two substantially U-shaped girders connected together. A carrying device is also provided for use with a crane in lifting and moving the racks.
