| Abstract(E) | As commercial vehicles have been used for a long time, there is an increasing need to accurately evaluate the aging of ammonia slip catalysts. In this study, modeling of the hydrothermal aging effect for platinum group metal catalyst was investigated. As for the simulation results of developed model, the change of ammonia oxidation reactivity and selectivity by hydrothermal aging could be calculated accurately. In addition to this, reaction path analysis revealed selectivity at low temperature are more sensitive compared to one at high temperature. |
