| 摘 要： | 用静态实验筛选出的大孔吸附树脂ＡＢ－８在固定床内对吸附法回收柠檬酸的动态过程进行了研究。通过对包含轴向扩散的动力学模型的计算求得总传质系数，并结合由经验式得出的淮膜传质系地出该传质过程属内扩散控制，并通过实验得到验证。

| Abstract: | Dynamic adsorption processes of recovery of citric acid in fixed-bed were studied with theadsorbent of AB-8, which was selected by static adsorption experiments. Connecting the totalmass transfer coefficient obtained from fixed-bed adsorption model and considering axial diffusionand the liquid film mass transfer coefficient obtained from empirical formula, the result showedthat the processes were intraparticle diffusion controlled, which had been verified by experiments. |
