Abstract

Traditional SCR control methods can't fit the high efficiency SCR and keep the coherence of production. Model-based SCR control methods is developed to compensate the defect. A simulation model for a Cu-zeolite SCR catalyst has been developed. The model is capable of predicting the conversion of NOX, NH3 slip and calculate the amount of urea on real time. It also can be used to study the impact of temperature, space velocity on NOX conversion and NH3 storage. Testing validations were taken based on WHTC test cycle. The results show that the average error between calculated and measured NOX conversion efficiency is about 3.4% during the test cycle. In general, good agreement between model prediction and the experimental data was achieved.
