Catalyst Exhaust gas Modeling |
Résumé : |
A reaction model, which is comprehensive and simple enough to be a base of the dynamic model, of the after-treatment of automobile exhaust gas was proposed. The studied catalyst was Pt- and Rh-supported alumina washcoated over a honeycomb. For attaining a short residence time, a small reactor, 2-73 mm long, was employed. To formulate the reaction rate, the subsets of reactions, CO oxidation, C3H6 oxidation, and N2O and NO reduction by CO or C3H6, were carried out separately over a wide range of gas composition at 140-340 °C. An overall model was built by combining the subset models. The results calculated with the proposed model well represented the experimental results. |
