The paper describes a two-dimensional model used to simulation of temperature field and composition of exhaust gases in a multisection catalyst converter run in transient and steady states. The model takes into consideration a phenomena of convection heat exchange, mass exchange in solid and gas phases, axial and radial heat conduction in monolith as well as chemical reactions and heat released during the reaction. The model was implemented to analysis of transient phases inside axial-symmetric, multisection catalytic converter with ceramic monolith during heating-up. On base of performed calculations one has accomplished an analysis of an impact of geometric parameters of individual sections of the catalyst on efficiency of the complete system.
