Abstract In industrial processes, the reduction of nitrogen oxides by ammonia on activated carbons is carried out at temperatures between 90 and 190 °C. Adsorption of NO and NH 3 on the catalyst was investigated separately. Reactions models for NO‐reduction by carbon and ammonia were derived from experiments carried out in an integral reactor. In each case, the formation of an adsorbed (NO 2 )‐complex is an important step. The kinetics of both reactions was described by modified Langmuir‐Hinshelwood equations.
