    摘要: The present invention discloses methods of separating gases using high performance UV cross-linked 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. These UV cross-linked MMMs were prepared by incorporating polyethersulfone (PES) functionalized molecular sieves such as AIPO-14 and UZM-25 small pore microporous molecular sieves into a continuous UV cross-linkable polyimide polymer matrix followed by UV cross-linking. The UV cross-linked MMMs in the form of symmetric dense film, asymmetric flat sheet membrane, or asymmetric hollow fiber membranes have good flexibility, high mechanical strength, and exhibit significantly enhanced selectivity and permeability over polymer membranes made from corresponding continuous polyimide polymer matrices for carbon dioxide/methane and hydrogen/methane separations. The MMMs of the present invention are suitable for a variety of liquid, gas, and vapor separations.

    摘要: The present invention is for crosslinked membranes and in particular for crosslinked poly(ethylene oxide)-cellulose acetate-silsesquioxane (PEO-CA-Si) organic-inorganic hybrid membranes and their use in gas separation. These crosslinked PEO-CA-Si membranes were prepared by in-situ sol-gel co-condensation of crosslinkable PEO-organotrialkoxysilane and CA-organotrialkoxysilane polymers in the presence of acetic acid catalyst during the formation of membranes. The crosslinkable PEO- and CA-organotrialkoxysilane polymers were synthesized via the reaction between the hydroxyl groups on PEO (or on CA) and the isocyanate on organotrialkoxysilane to form urethane linkages under mild conditions. The crosslinked PEO-CA-Si membranes exhibited both increased selectivity of CO2/N2 and CO2 permeability as compared to a CA membrane, suggesting that these membranes are very promising for gas separations such as CO2/N2 separation.

    摘要: Metal-organic framework (MOF)-polymer mixed matrix membranes (MOF-MMMs) have been prepared by dispersing high surface area MOFs (e.g. IRMOF-1) into a polymer matrix (e.g. Matrimid 5218). The MOFs allow the polymer to infiltrate the pores of the MOFs, which improves the interfacial and mechanical properties of the polymer and in turn affects permeability. Pure gas permeation tests show the incorporation of 20 wt-% of IRMOF-1 in Matrimid 5218 polyimide matrix results in 280% improvement in CO2 permeability without a loss of CO2/CH4 selectivity compared to those of the pure Matrimid 5218 membrane. This type of MOF-MMMs has significantly improved gas separation performance with dramatically high CO2 permeability (>35 barrer) and higher than 29 CO2/CH4 selectivity at 50° C. under 100 psig pressure, which are attractive candidates for practical gas separation applications such as CO2 removal from natural gas.

    摘要: New ionic liquid-solid-polymer mixed matrix membranes were proposed for gas separations such as CO2 removal from natural gas or N2. For the new mixed matrix membranes, the solids such as carbon molecular sieves, microporous molecular sieves, MCM-41 type of mesoporous molecular sieves, or polymer of intrinsic microporosity (PIM) are coated (or impregnated) with ionic liquids such as 1-butyl-3-methyl imidazolium bis[trifluoromethylsulfonyl]amide. The ionic liquids coated or impregnated solids are then dispersed in the continuous polymer matrix to form mixed matrix membranes. These hybrid mixed matrix membranes will combine the properties of the continuous polymer phase, the ionic liquids, and the dispersed ionic liquids coated or impregnated solids phase, which will possibly open up new opportunities for gas separation processes such as CO2 separation from natural gas or flue gas.

    摘要: The present invention discloses mixed matrix membranes (MMMs) containing polymer-functionalized low acidity, ultra low silica-to-alumina ratio, nano-sized SAPO-34 small pore molecular sieves and a continuous polymer matrix and methods for making and using these membranes. The surface functionalization of these molecular sieves provides a desired interfacial adhesion between SAPO-34 nano-particles and the continuous polymer matrix, which results in either no macrovoids or voids of less than 5 angstroms at the interface of the continuous polymer matrix and SAPO-34 in the MMMs. These MMMs, in the form of symmetric dense film, asymmetric flat sheet membrane, or asymmetric hollow fiber membranes, have good flexibility and high mechanical strength, and exhibit remarkably enhanced CO2 permeability (or CO2 permeance) and maintained CO2/CH4 selectivity over the continuous polymer matrices for CO2/CH4 separation. The MMMs of the present invention are suitable for a variety of liquid, gas, and vapor.

    摘要: The present invention is for novel high performance cross-linkable and cross-linked mixed matrix membranes and the use of such membranes for separations such as for CO2/CH4, H2/CH4 and propylene/propane separations. More specifically, the invention involves the preparation of cross-linkable and cross-linked mixed matrix membranes (MMMs). The cross-linkable MMMs were prepared by incorporating microporous molecular sieves or soluble high surface area microporous polymers (PIMs) as dispersed microporous fillers into a continuous cross-linkable polymer matrix. The cross-linked MMMs were prepared by UV-cross-linking the cross-linkable MMMs containing cross-linkable polymer matrix such as BP-55 polyimide. Pure gas permeation test results demonstrated that both types of MMMs exhibited higher performance for CO2/CH4 and H2/CH4 separations than those of the corresponding cross-linkable and cross-linked pure polymer matrices.
