A three-dimensional, steady-state computational model has been developed for analyzing the carbon monoxide oxidation reaction in a reactor filled with hopcalite catalyst, at low temperature. The mass, momentum, and chemical reaction equations are strongly coupled and solved using the COMSOL MULTIPHYSICS software in order to identify the effects of various transport processes and parameters for the oxidation of carbon monoxide. Therefore, the influence of pressure and temperature on the CO conversion was investigated in this paper. We have noticed that increasing the temperature at 313K we could obtain almost complete conversion of CO (95.67%) compared to the case of 300K where the CO conversion is 65% at a bigger pressure.
