Simulation of monolithic catalytic converters under transient operating conditions is reported. Model equations for heat and mass transfer with chemical reaction in monolithic honeycomb catalyst were discretized by using a collocation method, and the time integration was accomplished by a third-order semi-implicit Runge-Kutta algorithm. Important aspects of the analysis are the influence of radiation upon the solution of the governing equations; the temperature distribution on the catalyst, which for the majority of the operating conditions shows a maximum at a distance from the converter inlet approximately equal to the 85% of the monolith length; the pollutant concentration profile; and the time for catalyst heating up. © 1992.
