A comparative study of catalytic CO oxidation and selective CO oxidation over Pt-Al2O3 and CeO2-promoted Pt-Al2O3 catalysts has been investigated for the removal of a trace amount of CO from the reformed gas. The catalysts were prepared by sol gel and incipient wetness impregnation. CO oxidation and selective CO oxidation were carried out with a 5%Pt-Al2O3 and a 5%Pt-15%CeO2-Al2O3. The presence of 15%CeO2 inthe 5%Pt-Al2O3 dramatically improves the activities to CO oxidation and selective CO oxidation at low temperature
