Theoretical study of NOx removal from humid air by a hybrid system (catalyst combined with electron beam) was carried out. The purpose of this work is to study the possibility to decrease energy consumption for NOx removal. The kinetics of radiation catalytic oxidation of NO on the catalyst TiO2 surface under electron beam irradiation was elaborated. Program Scilab 5.3.0 was used for numerical simulations. Influential parameters such as inlet NO concentration, dose, gas flow rate, water concentration and catalyst contents that can affect NOx removal efficiency were studied. The results of calculation show that the removal effiiency of NOx might be increased by 8–16% with the presence of a catalyst in the gas irradiated field.
