Monolithic three way catalysts are wide been used to reduce the emission of combustion engines. Several Factors should be considered while designing the catalytic converter; however, it is a complex process involving the optimization of different physical and chemical parameters. Length, Cell densities, metal coverage, fuel composition is the simple Properties which ready influence the catalytic performance of the converter. In this paper a 3- Dimensional monolith catalytic converter has been modelled by using ANSYS Fluent. Flow and heterogeneous reactions are simulated within the catalytic converters. A surface reaction model is applied to predict the performance of a three-way Pt/Rh catalyst where stoichiometric fuel has been used Mixture. The concentrations of the gas species and the site species are attained. The simulation results are compared with the experimental data of a three-way catalyst and the results are with acceptable limit and shows good agreement with literature.
