Adsorption of gas mixtures on molecular sieves

Abstract

Danner and Wenzel (1969) obtained experimental data for adsorption of three binary gas mixtures (N2 + 0 2 , CO + 02, and CO + N2) on 5-A and 10-X molecular sieves. These zeolites adsorb in the following order of increasing strength of adsorption: 02, N2, CO. Danner and Wenzel reported that the theory of ideal adsorbed solutions (Myers and Prausnitz, 1965) explained their data

Size-Dependent Adsorption Models in Microporous Materials. 1. Thermodynamic Consistency and Theoretical Analysis

“…The thermodynamics of adsorbed mixtures constitutes a vast and well-established theory. Most of the efforts (ideal adsorbed solution theory (LAST), real adsorbed solution theory (RAST)) treat the equilibrium between a fluid and an adsorbed phase as similar to gas-liquid equilibria and, thus, introduce activity coefficients for the adsorbed phase (Myers and Prausnitz, 1965; Myers, 1973Myers, , 1983Talu and Myers, 1988).…”
