The paper presents the results of investigation concerning the determination of the rate of controlling the stage of the process reduction of nitrogen oxide by means of gaseous ammonia on the Polish active coke AKP-5. The influence of the scale factor, the grain diameter and temperature on the degree of the reduction of nitrogen oxide have been investigated. From the obtained results it is clear that the process takes place in the kinetic region and the optimum temperature of this process is 120°C. Apparent activation energy of reduction of nitrogen oxide on active coke has been calculated
