Abstract

This paper discusses the development of a new theoretical model based on resistance modeling approach to predict mixed matrix membrane (MMM) performance. To develop the proposed model, the element of MMM is considered as a unit cell of body centered cubic (BCC). The network of permeation resistances are developed based on this unit cell. The main parameters considered and discussed are: dispersed filler loading, polymer matrix permeability, dispersed filler permeability, interphase permeability and interphase thickness. The results generated from the proposed model have been verified using seven cases through the published experimental data. Excellent agreement has been obtained in most cases between the model results and the selected published values. Thus, the newly proposed model is capable in predicting the permeability and selectivity for all known MMM morphologies.
