The kinetics of selective non-catalytic reduction of NO using pyrolyzed urea solution with reaction kinetic method are studied and effects of O ₂ and H₂0 concentration on NO reduction and N₂O formation are discussed. The products of urea pyrolysis are mainly NH ₃ and UNCO, so the reaction scheme used in reaction kinetic method is based on mechanism of Thermal DeNO_x with NH₃ and oxidation of HNCO. Calculated results are compared with experimental data which were carried out by Koebel and Elsener, and show the reasonable agreement. We also investigate the role of each elementary reaction using sensitivity analysis and determine the reaction mechanism of NO reduction using urea.
