  • Catalyst for reductive conversion of nitrogen oxides in waste gases
    Patent number: 4789533
    Abstract: Catalyst for the reductive conversion of nitrogen oxides, optionally accompanied by sulfur dioxides, in waste gases, produced by the impregnation of a support, for example, a TiO.sub.2 support, with a vanadium alkoxide, and treatment of the impregnated support in the oxygen-containing gas current. The catalyst brings about a conversion of the nitrogen oxides even at a relatively low temperature of 150.degree. to 350.degree. C.
    Type: Grant
    Filed: June 3, 1987
    Date of Patent: December 6, 1988
    Assignee: Lonza Ltd.
    Inventors: Alfons Baiker, Peter Dollenmeier, Marek Glinski
