The effects of valence state of copper supported on charcoal on the CO adsorption perfor-mance and CO desorption kinetics were investigated by means of XPS and TG.The results indicate thatCO may be selectively adsorbed on the Cu(I)sites and the desorption is a second order reaction with anactivation energy of 24.27kJ/mol.Using a bench-seale PSA apparatus,CO can be purified fromCO-N_2 and CO-CO_2-N_2 gas mixtures separately with CO concentration increases from 31％,25％to98％,96％,net desorption of 26ml/g,22ml/g and recovery of about 95％.
