    摘要: The present invention discloses a novel method of making high performance mixed matrix membranes (MMMs) using stabilized concentrated suspensions of solvents, uniformly dispersed polymer stabilized molecular sieves, and at least two different types of polymers as the continuous blend polymer matrix. MMMs as dense films or asymmetric flat sheet or hollow fiber membranes fabricated by the method described in the current invention exhibit significantly enhanced permeation performance for separations over the polymer membranes made from the continuous blend polymer matrix. MMMs of the present invention are suitable for a wide range of gas, vapor, and liquid separations such as alcohol/water, CO2/CH4, H2/CH4, O2/N2, CO2/N2, olefin/paraffin, iso/normal paraffins, and other light gases separations.

    摘要: This invention discloses a composition of, a method of making, and an application of high plasticization-resistant chemically cross-linked organic-inorganic hybrid membranes such as cross-linked cellulose acetate-cellulose triacetate-polyurethanepropylsilsesquioxane membranes. These cross-linked membranes with covalently interpolymer-chain-connected hybrid networks were prepared via a sol-gel condensation polymerization of cross-linkable organic polymer-organosilicon alkoxide precursor membrane materials. CO2 plasticization tests on these cross-linked membranes demonstrate extremely high CO2 plasticization resistance under CO2 pressure up to 5516 kPa (800 psig). These new cross-linked membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as desalination.

    摘要: The present invention discloses an approach for making mixed matrix membranes (MMMS) and methods for using these membranes. These MMMs contain a continuous polymer matrix and dispersed microporous molecular sieve particles. This invention also pertains to control of the thickness of the thin dense selective mixed matrix membrane layer that is equal to or greater than the particle size of the largest molecular sieve particles for making large scale asymmetric MMMs. In particular, the invention is directed to making asymmetric flat sheet MMM by a phase inversion technique. The MMMs of the present invention exhibit at least 20% increase in selectivity compared to the polymer membranes prepared from their corresponding continuous polymer matrices. The MMMs of the present invention are suitable for a variety of liquid, gas, and vapor separations.

    摘要: The present invention discloses a method of making polymer functionalized molecular sieve/polymer mixed matrix membranes (MMMs) with either no macrovoids or voids of less than several Angstroms at the interface of the polymer matrix and the molecular sieves by incorporating polyethersulfone (PES) or cellulose triacetate (CTA) functionalized molecular sieves into a continuous polyimide or cellulose acetate polymer matrix. The MMMs, particularly PES functionalized AlPO-14/polyimide MMMs and CTA functionalized AlPO-14/CA MMMs have good flexibility and high mechanical strength, and exhibit significantly enhanced selectivity and/or permeability over the polymer membranes made from the corresponding continuous polymer matrices for carbon dioxide/methane (CO2/CH4), hydrogen/methane (H2/CH4), and propylene/propane separations. The MMMs are suitable for a variety of liquid, gas, and vapor separations such as deep desulphurization of gasoline and diesel fuels, ethanol/water separations, pervaporation dehydration of aqueous/organic mixtures, CO2/CH4, CO2/N2, H2/CH4, O2/N2, olefin/paraffin, iso/normal paraffins separations, and other light gas mixture separations.
