MULTICOMPONENT ADSORPTION DYNAMICS CALCULATIONS EMPLOYING ADSORPTION POTENTIAL AND IDEAL ADSORBED SOLUTION THEORIES

摘要

A model is described for predicting multicomponent adsorption equilibrium based on an approach combining the Adsorption Potential and the Ideal Adsorbed Solution (IAS) theories. This approach was mentioned briefly by Myers, who considered the Adsorption Potential theory in the form of the Dubinin-Radushkevich isotherm. Very recently, Stoeckli and coworkers extended the method to the Dubinin-Astakov isotherm. They were able to predict breakthrough curves for the binary adsorption of several vapors on activated carbon, under isothermal conditions, using LAS and the Dubinin-Radushkevich isotherm. Here, a different form of the characteristic curve is employed and the theory is applied to a gas mixture with several components under nonisothermal conditions.
