Method for removing nitrogen oxides from nitrogen oxide-containing gases
Patent
·
OSTI ID:6357260
A method is disclosed for removing nitrogen oxides from a nitrogen oxide-containing gas by contacting the gas with ammonia excited by ultraviolet irradiation in the presence of a catalyst to react the nitrogen oxides with the ammonia. According to the method, the reaction of nitrogen oxides with ammonia proceeds more rapidly than in the case of prior art methods.
