Development of a Mixed-Matrix Membrane for Pervaporation
Separation Science and Technology, 1994Abstract In the production of pure alcohol, pervaporation is developing into an important technology. In this study, in order to improve the performance of the pervaporation process, a mixed-matrix polymer-zeolite membrane is developed. In the preparation of these membranes, cellulose acetate as base polymer, acetone or DMF as solvent, and 13X or 4A ...

High performance ZIF-8/6FDA-DAM mixed matrix membrane for propylene/propane separations
Journal of Membrane Science, 2012 We report significantly enhanced propylene/propane (C 3H 6/C 3H 8) selectivity in mixed matrix membranes fabricated using 6FDA-DAM polyimide and a zeolitic imidazolate framework (ZIF-8). Equilibrium isotherms and sorption kinetics of C 3H 6 and C 3H 8 at

, 2016 Mixed matrix membranes are prepared from zeolites and polymers, such as polyimides, in a void free fashion where either no voids or voids of less than several Angstroms are present at the interface of the polymer and the zeolite by bonding (hydrogen, ionic, or covalent) functional groups on the zeolite with functional groups on the polymer.

Carbon dioxide selective mixed matrix composite membrane containing ZIF-7 nano-fillers
Journal of Membrane Science, 2013 Mixed matrix materials made from selective inorganic fillers and polymers are very attractive for the manufacturing of gas separation membranes. But only few of these materials could be manufactured into high-performance asymmetric or composite membranes.

Mixed matrix membrane development
Membrane Technology, 2002Abstract: Two types of mixed matrix membranes were developed by UOP in the late 1980s. The first type includes adsorbent polymers, such as silicalite‐cellulose acetate (CA), NaX‐CA, and AgX‐CA mixed matrix membranes. The silicalite‐CA has a CO2/H2 selectivity of 5.15 ± 2.2. In contrast, the CA membrane has a CO2/H2 selectivity of 0.77 ± 0.06.

Hollow filler based mixed matrix membranes
Chemical Communications, 2010Micron-sized hollow spheres with zeolitic shell were used as inorganic fillers in PDMS-based mixed matrix membranes, overall enhancing solvent permeabilities as compared to traditional zeolite fillers, while selectivities were maintained.

Permeation models for mixed matrix membranes
Journal of Colloid and Interface Science, 2008Permeation models for mixed matrix membranes (MMMs) are discussed. A new model is proposed for the effective permeability of a species in MMMs. The model takes into account the presence of interfacial layer (shell) at the surface of the core filler particles.
