Equilibrium adsorption of binary mixtures of gases by zeolites and the state of the adsorption phase

A method for analyzing the state of the adsorption phase was developed on t he basis of statistical thermodynamics for the case of equilibrium adsorpti on of binary gaseous mixtures. The procedure for treating experimental data to determine the Helmholtz energy and other thermodynamic functions of a m ixture of molecules occluded within zeolite cavities was proposed. A measur e of ideal behavior of a mixture of a small number of molecules in the micr opore was formulated; in the asymptotic limit such a behavior leads to the Raoult law and to assumption of the validity of the Raoult law when moving along the line of constant value of the Gibbs integral in the ideal adsorpt ion solution theory.
