The Maxwell-Stefan formulation for mixture diffusion, in principle, allows us to predict the diffusion characteristics of mixtures on the basis of information of the pure component Maxwell-Stefan diffusivities at zero loading. The interaction between the diffusing, sorbed, species is taken into acco

We develop an analytic solution of the Maxwell-Stefan equations describing steady-state diffusion of n-component mixtures across a zeolite membrane. In the development of the analytic solution we assume Langmuirian behaviour of the pure components and that the mixture sorption can be calculated from
