The aim of this paper is to investigate the effect of catalyst particle diameter and of pressure on CO oxidation reactions. The numerical investigation was done for three different pressures (1 bar, 0.7 bar, 0.4 bar) and three catalyst particle diameters (0.1mm, 0,15mm, 0,2mm) at low temperature (300-313K). In order to achieve less than 10 ppm CO levels needed for PEM fuel cell anode flux, CO conversions of 90% or more are needed in the reactor. Our study concluded that in the case of 0.1 mm catalyst particle diameter the conversion of CO is over 99% regardless of the pressure and temperature used. In the other cases (0.15mm, 0.2mm) it was found that a temperature above 310K is required in order to have a CO conversion of 90% or more, regardless of the pressure used.
