Numerical Study of Multicomponent Competitive Adsorption in Activated Carbon Bed

建立了活性炭床多组分竞争吸附动态模型,并利用数值方法求解。计算结果表明采用有限差分数值方法能较好地预测多组分动态穿透曲线,同时能较好地反映多组分气体的竞争吸附特性。该数值计算方法能辅助实验工作进行预测,也可以用于其它竞争吸附过程的数值计算。

The dynamic multicomponent competitive adsorption model was developed in activated carbon bed, and it was solved by using numerical technique. The results show that the finite difference method can preferably predict break through curves of multicomponent competitive adsorption systems, and reflect the adsorption characteristics, This numerical method can assist the experimental work for predicting, and also be used for other competitive adsorption process.
