On the Breakdown of Dynamic Adsorption of gases Through Active Carbon Column

Abstract

This paper is concerned with the theories and the experimental results on the breakdown of dynamic adsorption of gas streams through active carbon column.
Kinetic theory of dynamic gas adsorption has been developed as the concept of adsorption wave by many investigators, and it interpretes the observed data in the wide range of adsorption conditions, except both of the effluent gas concentration at the initial range of breakdown and of the relation between the influent gas concentration and the breakdown time. Here, the theory was discussed in comparison of the observed results.
Also, the reviews are given on some semiempirical methods, like Mecklenberg's concept, MTZ approach and the pulse test methods.
The relation between the dynamic and static adsorption was considered at last, which lead to the new and convenient method to obtain the general relation between the influent gas concentration and the breakdown time.
