Abstract

In order to improve air quality, catalytic converters have been extensively employed throughout the world. These monolithic catalytic converters are very effective in reducing pollution only after they have heated up. The catalyst warming-up process takes some time and during this period a considerable amount of pollutants, especially hydrocarbons, is released into the atmosphere. In this paper, a one-dimensional model for the hydrocarbon propylene was developed, taking into account heat and mass transfer between the exhaust gas and the catalyst surface and the catalytic reaction. The equations so formed are a set of ordinary differential equations (ODEs) and a partial differential equation (PDE). The ODEs are solved using the Runge-Kutta method of fourth order and the PDE by backward implicit scheme. The effect of varying the inlet gas temperature and initial catalyst solid temperatures on conversion of propylene was analysed.
