| Abstract: | Assuming three-dimensional isotropy for the suspended particles of cubes or spheres in a polymer matrix, resistance models are developed for adsorbent-filled polymer membranes. These are compared with the existing models in the literature and they agree very well. Monotonically increasing or decreasing permeabilities of composite membrane are well described by these models. The model calculations are compared with several experimental sets of data for alcohols and gases in the literature and proven to be very good. However, there are unexplained experimental observations of permeability behavior as the amount of fillers increase in polymer. Further studies are recommended to directly measure the zeolite permeabilities by measuring the actual throughput. This information is vital in interpreting the data of permeations and separations through filled membranes. |
