Abstract
Temperature rise during the exothermic reduction of nitrogen oxides contained in a carbon dioxide-rich gas stream to nitrogen by contacting the gas stream with ammonia in a reactor containing a reduction catalyst is controlled by recycling a portion of the gaseous effluent from the reactor to the gas stream prior to its introduction into the reactor, thereby cooling the reactor contents without diluting the carbon dioxide in the effluent.
