  • Catalyst for the oxidation of ammonia
    Patent number: 3985681
    Abstract: There are provided oxidation catalysts having a specific surface ranging m 12 to 100 m.sup.2 /g and containing as their main constituent either an oxide of cobalt or an oxide of bismuth. The catalysts further contain a promoter in the form of a rare earth oxide or thorium oxide, and they may also contain at least one oxide of manganese, iron, magnesium, chromium or niobium. Such catalytic compositions can be used for the oxidation of ammonia in a solid bed or in a fluidized bed.
    Type: Grant

    Assignee: Societe Chimique de la Grande Paroisse, Azote et Produits Chimiques
    Inventors: Michel Senes, Michel Pottier, Jean-Francois Courdier
  • Catalytic oxidation of ammonia
    Patent number: 3947554
    Abstract: This invention relates to the catalytic oxidation of ammonia. The catalytic compounds are complex catalysts with limited porosities, with specific surface areas between 0.02 and 2 m2/g, containing an active material bonded by ceramic-type bonds to the elements of a refractory carrier made of refractory oxides such as magnesia, zirconia, silica.Such compounds are suitable for the oxidation of ammonia over fixed beds or fluidized beds.
