Prediction of the Relative Permeability of Gases in Mixed Matrix Membranes. Paper Accepted to be published in Journal of Membrane Science

In the present work, the existing theoretical models for the estimation of gas permeation through mixed
matrix membranes (MMMs) were tested using the available literature data and the results are discussed
in detail. Based on the analysis, the variables affecting the relative permeability ofgases have been identified.
By incorporating the rigidiñed interÍacial layer between the molecular skve phase and the polymer
phase, a new methodology was developed by using Pal model as a base. The presãnt proposed methodology,
showed an accurate prediction of the permeability of gases through different MMMs. The present
methodology for the estimation of permeabitity was validated using the available literåture data, and a
satisfactory agreement was found.
