  • 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.
