This study is concerned with the oxidation of carbon monoxide on Platinum and Platinum -Palladium catalysts. Catalysts were made by the impregnation method and flow reactor was used in the catalytic reaction. As for the mixed gases, carbon monoxide concentration varied from 1 to 4% and that of oxygen from 1 to 4%. Na was used as carrier gas and GHSV varied from 24,000h-1 to 60, 000h-1. The temperature range was from 200 to 600℃. It was also taken into consideration that the heat and mass transfer resistance of cur catalysts was negligible in the study. Experimental results showed that Platinum-Palladium catalyst was about 1.5∼3.90 superior to Platinum catalyst in conversion yield. When we used Platinum-Palladium catalyst, we observed that carbon monoxide oxidation was found to be 1st order with respect to carbon monoxide concentration. Activation energy of Pt-Pd catalyst was 23.5kcal/mol.
