Estimating CO2/N2 permselectivity through Si/Al = 5 small-pore zeolites/PTMSP mixed matrix membranes: influence of temperature and topology

Abstract: In the present work, the effect of zeolite type and topology on CO2 and N2 permeability using zeolites of different topology (CHA, RHO, and LTA) in the same Si/Al = 5, embedded in poly(trimethylsilyl-1-propyne) (PTMSP) is evaluated with temperature. Several models are compared on the prediction of CO2/N2 separation performance and then the modified Maxwell models are selected. The CO2 and N2 permeabilities through these membranes are predicted with an average absolute relative error (AARE) lower than 0.6% taking into account the temperature and zeolite loading and topology on non-idealities such as membrane rigidification, zeolite-polymer compatibility and sieve pore blockage. The evolution of this structure-performance relationship with temperature has also been predicted.
