    摘要： 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.

    摘要翻译： 含有一氧化二氮和氨的气流与含有沸石的催化剂组合物接触。 N2O在低温下以高效率的方式还原成N2和H2O。 氨介导的一氧化二氮的还原可以从具有低至1％的N 2 O浓度的气流中实现。 气流还可以选择性地接触用于还原NOx的催化剂组合物。 以这种方式，N2O和NOx处理可以在单个工艺流中实现。
