Abstract
In this research we developed surface kinetic model with detailed reaction mechanisms for simulating reaction dynamics of NOx Storage& Reduction (NSR) Catalyst and three-way catalyst (TWC). Simulation results showed that surface site coverage strongly dominates catalytic reaction characteristics especially in transient state. So we confirmed that the surface kinetic model could play important roles in a useful tool for understanding detail reaction dynamics and searching the optimized operating conditions in the development of automotive catalysts which was always exposed to transient conditions. And the detailed reaction mechanisms in TWC and NSR catalyst were discussed on the basis of the calculated surface site coverage.
