(234bn) Model based Simulation of Mobile Emission Catalysts using BASF CatSim

With the increasingly stringent emission regulations and more demanding (real-life) engine/vehicle operating conditions required during test drive cycles (RDE/FTP/US06) to meet emission requirements, model based simulation of mobile emission catalysts has gained popularity. Model based simulations provide a cheaper and faster way to optimize a catalyst system depending on the type of vehicle and emission requirements, as well as provide research insight to enable catalyst development and improvement. CatSim has been used at BASF for a long time as a tool to model emission catalysts. The kinetic model development in CatSim can be based on lab reactor data, further validated with engine/vehicle data. This poster will provide details on CatSim capabilities, as well as give an example of its usage to optimize a catalyst system.
