Method of removing nitrogen oxides from an exhaust |
| abstract |
A method of removing nitrogen oxides from an exhaust which comprises the steps of contacting an exhaust containing nitrogen oxides and ammonia with a reducing catalyst received in a reactor to reduce the nitrogen oxides to nitrogen gas, wherein iron ore catalyst lumps having a particle size of 25 mm or less and forming a catalyst bed in the reactor are used as a reducing catalyst; the iron ore lumps of the catalyst bed are let to fall gravitationally through the reactor continuously or intermittently; and the iron ore catalyst lumps discharged from the reactor are either used as raw material for iron manufacture or fed back to the reactor to be reused as a reducing catalyst after being sieved. |
