Abstract
The study addresses one of the fundamental issues in the area of mathematical modeling and quantitative analysis of the process of multicomponent diffusion in microporous materials. One of the elements of mathematical models of such processes is the thermodynamic equilibrium between the bulk phase and the solid. This results from the fact that surface diffusion takes place in the adsorbed phase. It is illustrated what kind of change occur in the isotherms of pure strongly adsorbable species in comparison with isotherms of these species in binary mixtures. The reason of these changes are explained by analyzing isotherms with different values of affinity coefficients. The RAS (Real Adsorption Solution) method was used to compute sorption isotherms for selected binary mixtures of strongly adsorbable organic compounds on activated carbon. The methods of approximate determination of isotherms of components in mixture for weakly and strongly adsorbable species obtained according to IAS (Ideal Adsorption Solution) and RAS methods are proposed. The results are illustrated by several examples of mixtures of some common hydrocarbons and for two kinds of porous material. Thermodynamic calculations were performed for mixtures of two components subject to adsorption and at high excess of inerts.
