| titleOfInvention | Nitrogen oxide catalytic reduction purification method |
| abstract | Provided is a method for efficiently purifying nitrogen oxides with ammonia at low temperature using an inexpensive zeolite catalyst not supporting an active metal and ammonia. A catalyst comprising a hydrogen-type and / or ammonium-type β zeolite is added to a processing gas containing nitrogen monoxide and nitrogen dioxide as a reducing component without supporting a catalytically active metal species, A method for catalytically reducing and purifying nitrogen oxides, which comprises contacting them. The molar ratio of silica (SiO 2 ) to alumina (Al 2 O 3 ) in the β zeolite is 20 to 200, and the content of nitrogen dioxide in the processing gas is 0.5 to 1.5 in terms of molar ratio to nitrogen monoxide. The treatment temperature is preferably 150 ° C. or higher. [Selection figure] None |
