【摘要】 用静态法测定了CO、N2、CH4、CO2在NA型络合吸附剂上的平衡吸附,并用吸附柱动态实验装置测定了CO与N2、CH4、CO2二元混合体系以及CO、N2、CH4及CO、CO2、CH4三元混合体系的动态吸附分离性能。实验结果表明,该吸附剂对CO有很高的选择性,与N2和CH4的分离系数较高,对CO2有一定吸附量,但基本不影响CO在该吸附剂上的穿透吸附量。CO与其他组分的分离系数随CO分压的增大而降低。更多还原

【Abstract】 The adsorption equilibrium of CO, N₂, CH₄ and CO₂ on the adsorbent NA were investigated by static method,and the dynamic adsorption behaviors of CO/N₂, CO/CH₄, CO/CO₂, CO/N₂/CH₄, and CO/CO₂/CH₄ on NA were studied with adsorption column. The results showed that the adsorbent NA has excellent selective adsorption for CO. The separation coefficients of CO and N₂, CH₄ were high. Adsorbent NA could adsorb CO₂ slightly, but that does not influence the breakthrough adsorption of CO. The separation coefficient of CO from other components decreases with the partial pressure of CO₂ increase.更多还原
