  • Dehydrogenation process
    Patent number: 4520223
    Abstract: Platinum or other platinum-group metals can be deposited substantially on the surface only of pellets of a refractory catalyst support by impregnation with an aqueous solution of such as hexammonium platinum tetrasulfite. The resulting catalysts contain relatively small total amounts of platinum-group metal positioned primarily at the surface, yet are as highly active as catalysts uniformly impregnated throughout the body of the pellet and containing much larger amounts of platinum-group metal. The catalyst further can contain rhenium.
    Type: Grant
    Filed: October 11, 1983
    Date of Patent: May 28, 1985
    Inventors: Roger N. McGinnis, Lewis E. Drehman, Emory W. Pitzer
  • Platinum group metal catalyst on the surface of a support and a process for preparing same
    Patent number: 4431750
    Abstract: Platinum or other platinum-group metals can be deposited substantially on the surface only of pellets of a refractory catalyst support by impregnation with an aqueous solution of such as hexammonium platinum tetrasulfite. The resulting catalysts contain relatively small total amounts of platinum-group metal positioned primarily at the surface, yet are as highly active as catalysts uniformly impregnated throughout the body of the pellet and containing much larger amounts of platinum-group metal. The catalyst further can contain thenium.
