摘      要：Wet scrubbing combined with ozone oxidation has become a promising technology for simultaneous removal of SO_2 and NO_x in exhaust *** this paper,a new 20-species,76-step detailed kinetic mechanism was proposed between O_3 and NO_*** concentration of N_2O_5 was measured using an in-situ IR *** numerical evaluation results kept good pace with both the public experiment results and our experiment *** reaction parameters for the generation of NO_2 and N_2O_5 during the NO ozonation process were investigated by a numerical simulation *** effect of temperature on producing NO_2 was found to be *** produce NO_2,the optimal residence time was1.25 sec and the molar ratio of O_3/NO about *** the generation of N_2O_5,the residence time should be about 8 sec while the temperature of the exhaust gas should be strictly controlled and the molar ratio of O_3/NO about *** study provided detailed investigations on the reaction parameters of ozonation of NO_x by a numerical simulation method,and the results obtained should be helpful for the design and optimization of ozone oxidation combined with the wet flue gas desulfurization methods（WFGD） method for the removal of NO_x.
