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

Abstract

Abstract. 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 TiO 2 surface under electron beam irradiation was elaborated. Program Scilab 5.3.0 was used for numerical simulations. Infl uential parameters such as inlet NO concentration, dose, gas fl ow rate, water concentration and catalyst contents that can affect NO x removal effi ciency were studied. The results of calculation show that the removal effi ciency of NO x might be increased by 8-16% with the presence of a catalyst in the gas irradiated fi eld.
