Abstract

A methodology based on a molecular simulation technique and permeation theory was applied to the systematic estimation of permeabilities of inorganicgases (Ar, He, Ne, N-2, O-2) through an MFI-type silicalite membrane. The estimated inorganic gas permeabilities were in qualitative agreement with available experimental data. The estimated permeabilities decrease in the order N-2 > O-2 > Ar > Ne > He. This result means that their permeation mechanism is significantly influenced by their adsorption properties rather thanby their kinetic properties, and can be described by the adsorption model. The qualitative agreement of the calculated permeability with experiment suggests that the method used is a leading candidate for the theoretical approach to the prediction of the performance of zeolite membranes.
