  • SELECTIVE CATALYTIC REDUCTION ON N2O
    Publication number: 20090011927
    Abstract: A gas stream containing nitrous oxide and ammonia is contacted with a catalyst composition containing a zeolite. N2O is reduced to N2 and H2O at low temperatures in a highly efficient manner. Ammonia-mediated reduction of nitrous oxide can be effectuated from gas streams having N2O concentrations as low as 1%. The gas stream may also contact a catalytic composition selective for the reduction of NOx. In this way, N2O and NOx treatment may be effectuated in a single process stream.
    Type: Application
