Abstract
A three-dimensional model of a single-channel honeycomb NH3-SCR catalytic converter was developed to simulate the catalytic reduction of NO and the simultaneous oxidation of CO and C7H8. The accuracy of the model was validated against experimental data. The effects of different operation conditions (such as space velocity, temperature, and inlet concentration) on the conversion efficiency of NO and CO were investigated, along with the distribution of gas components at various locations within the catalyst channel and along the catalyst wall. Compared to inlet gas concentrations, space velocity and temperature had a more significant impact on NO catalytic reduction and CO oxidation. Additionally, the oxidation behavior of toluene (C7H8) and its influence on the removal efficiency of NO and CO were analyzed by the simulation at the same time.
