Cu(I)Y adsorbent was prepared by reduction of Cu(II)Y which was prepared by ion exchange between the NaY zeolite and a solution of Cu(II) chloride. The dynamic adsorption capacity of Cu(I)Y for CO was calculated by adsorption breakthrough curve measured on a fixed bed at 30°C and 0.006 MPa (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 approximately consistent with experimental results. Then a five-bed VPSA process for separating CO from syngas on this adsorbent was dynamically simulated with Aspen Adsorption software with the adsorption pressure of 0.68 MPa (g) and the desorption pressure of -0.075 MPa (g). The results showed that CO was enriched from 32.3% to 95.16%–98.12%, and its recovery was 88.47%–99.44%.
