| 摘 要： | 本文利用二元共吸附平衡关系,并考虑固体相传质阻力,建立了固定床共吸附等温理论模型。借助于纯组分等温线数据,经数值法求解上述模型,获得了氮、氧二元混合物在5A沸石分子筛柱和炭分子筛柱内的共吸附穿透曲线。该计算曲线与本文相同条件下的实测结果吻合。

| Abstract: | According to the binary equilibrium isotherms and taking account o1 the effect of the solid phase mass transfer resistance, the isothermal theoretical mo- dal pertaining to co-adsorption fixed bed is established. By means of the pure- component isotherms, the numerical solutions to the model give the breakthrough curves for oxygen-nitrogen system in fixed beds of MSZ-5A and MSC. The calculated curves are in a good agreement with the experimental results obtained under same conditions. |
