A Realization for SCR Catalytic Converter Model Based on MATLAB/Simulink

In this paper, the reaction kinetics of the selective catalytic reduction (SCR) is briefly introduced, and a non-cell mathematical model describing the thermal and chemical process of the SCR catalytic converter is given. Based on the one-cell model, identical SCR cell models can be seriously connected to simulate a real SCR converter performance. Consequently, the SCR catalytic converter model in MATLAB/Simulink is realized and detailedly described. The simulation results show satisfying performance of the models. Because of the feasibility and the simplicity, the model will attribute great benefits to the SCR control strategy design in the future.
