Two-stage catalysis of engine exhaust |
摘要 |
The invention relates to reduction of nitric oxide in exhausts from hydrocarbon burning engines. The nitric oxide is reacted with ammonia over a first catalyst and then the excess ammonia is reacted with oxygen present in the exhaust gas over a second catalyst. The resulting effluent stream has greatly reduced nitric oxide content without having an objectionable content.
