Deconvolution of permeance in supported nanoporous membranes
Nanoporous membranes--porous membranes generally having a porosity below 1 nm--have attracted the attention of many researchers because of their potential for technological advances in gas separations and shape selective catalysis. Permeation experiments often constitute a significant contribution to the characterization of these membranes. As the dimensions of a pore approach that of the molecule, transport generally becomes extremely sensitive to the molecular dimensions of the probe gas and very high separation factors have been reported for ceramic, zeolite, and nanoporous carbon membranes of this type. The purpose of this article is to introduce a technique that can be used to dissect the relative contributions of the overall permeances through molecular sieving membranes.
