Abstract:
Cu-Mn catalyst suitable for the CO removal from gas via low-temperature catalytic oxidation was prepared by means of coprecipitation. The product was then characterized using XRD and SEM. It is found that the amorphous catalyst is of high catalytic activity for CO oxidation at room temperature. Moreover, the catalytic isotherm of CO oxidation on the Cu-Mn catalyst bed at 50 - 80℃ was obtained, and the corresponding intrinsic reaction kinetics was investigated. Experimental results show that the surface reaction on the catalyst bed plays the most important role in the control of reaction rate, and that, when eliminating the internal and external diffusion, the catalytic oxidation of CO on the Cu-Mn catalyst bed is a first-order reaction with an activation energy of 43.0 kJ/mol.
Key words: copper-manganese catalyst, carbon monoxide, catalytic oxidation, intrinsic reaction kinetics
