Abstract
The features of cyclic adsorption processes are considered and the fact of necessity to predict a decrease in the dynamic activity of adsorbents during their operation is exhibited. By analogy with recycling chemical processes, phenomenological concepts of the general pattern of sorbent deactivation were developed, which made it possible to form mathematical models of trivial and prolonged deactivation in cyclic and continuous adsorption processes. Simple approximate equations are derived that sllow predicting the change in the dynamic activity of the adsorbent under conditions of long-term operation on the basis of short-term laboratory studies. Examples of the results of predicting the operation of various adsorbents during the purification of gas and liquid phase streams are presented. The developed mathematical models provide acceptable convergence of the calculation results with experimental data.
