We tried modeling of ammonia slip catalyst (ASC) for the purpose of model-based development of Urea-SCR system which is NOx purification device for diesel exhaust gas. In this report, we introduce the ammonia oxidation model on the PGM catalysts and the parameter identification method with genetic algorithm. The developed ammonia oxidation model can predict the influence of SV and PGM loading amount with high accuracy and is therefore expected to be useful as a kinetic model of PGM catalyst for the Dual layer (SCR+PGM)ASC.
