The influences of oxygen, water vapor, ammonia and hydrogen concentration on DeNOx process by ammonia addition were investigated by varying their initial concentration levels and the reaction temperature over wide ranges. The experiments were carried out with use of a flow reactor system and by measuring nitric oxide and ammonia concentration. The experimental results were compared to the computer simulations based on the reaction scheme proposed by Lyon et al. While the Lyon reaction scheme predicts qualitatively the influences on the reaction process due to the initial concentrations, large differences are found between them in lower temperature region, particularly in the case of oxygen and water vapor effect. The prediction for the influence of hydrogen and ammonia was improved by the modification of some reaction rate constants, however, barely improved for that of oxygen and water vapor.
