Kinetic modelling of NO heterogeneous radiation-catalytic oxidation on the TiO₂ surface in humid air under the electron beam irradiation

Theoretical study of NO_x 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 NO_x 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 fl ow rate, water concentration and catalyst contents that can affect NO_x removal efficiency were studied. The results of calculation show that the removal efficiency of NO_x might be increased by 8-16% with the presence of a catalyst in the gas irradiated field.
