On the condition of adequate air supply, complete removal of carbon monoxide,occurred above 650℃. Using catalysts, the oxidation of carbon monoxide occurred at lower temperatures; on both MnO2 and 30% MnO2-70% CuO at 250℃, on CuO at 450℃, on 50% MnO2-50 % CuO at 200℃, and on 70 % MnO2-30 % CuO at 180℃. Manganese dioxide (p-type) showed higher activity than cupric oxide (n-type) and a catalyst consisting of 60 % MnO2-40 % CuO had the highest activity of all the MnO2-CuO mixture. Over the range of transitional temperature, carbon monoxide removal efficiency decreased linearly with increasing inlet carbon monoxide concentration while temperature was fixed. Residence time of gases in the catalytic reactor, in the range of 0.9 to 1.8 seconds, gave no effect on carbon monoxide conversion.
