✦ Synopsis
The relations proposed by Ash and Barrer[l] on the basis of the thermodynamics of irreversible processes for the description of surface flow are transferred to the adsorption kinetics of binary gas mixtures. With the use of several simplifying assumptions (highly different adsorption behaviour of the two components, negligible "cross coefficients", applicability of the Langmuir model for the equilibria), an analytical expression for the description of sorption kinetics of binary mixtures is derived, which provides a satisfactory description of experimental data obtained by us for the mixture adsorption system benzene-n-heptane/NaX-zeolite.
