The dynamic adsorption capacity of Cu（1）Y for CO was calculated by adsorption breakthrough curve measured on a fixed bed at 30~C and 0.006MPa （g） of CO partial pressure. The calculated CO adsorption capacity was 2.14 mmol/g, 37.5 times as much as that of NaY zeolite. The adsorption breakthrough curve experiment was also simulated with Aspen Adsorption software and the results were approxi- mately consistent with experimental results. Then a five- bed VPSA process for separating CO from syngas on this adsorbent was dynamically simulated with Aspen Adsorp- tion software with the adsorption pressure of 0.68 MPa （g） and the desorption pressure of -0.075MPa （g）.
