摘要： The present invention discloses microporous UZM-5 zeolite membranes, methods for making the same, and methods of separating gases, vapors, and liquids using the same. The small-pore microporous UZM-5 zeolite membrane is prepared by two different methods, including in-situ crystallization of one or more layers of UZM-5 zeolite crystals on a porous membrane support, and a seeding method by in-situ crystallization of a continuous second layer of UZM-5 zeolite crystals on a seed layer of UZM-5 zeolite crystals supported on a porous membrane support. The membranes in the form of disks, tubes, or hollow fibers have superior thermal and chemical stability, good erosion resistance, high CO2 plasticization resistance, and significantly improved selectivity over polymer membranes for gas, vapor, and liquid separations.

摘要： This invention describes a new concept of flexible template-directed microporous partially pyrolyzed polymeric membranes which have greatly improved performance in separation of gas pairs compared to their precursor polymeric membranes. Organic hosts, such as crown ethers, cyclodextrins (CDs), calixarenes (CXs), and spherands, or polymeric additives, such as poly(ethylene glycol) (PEG) and polyvinylpyrrolidone (PVP) were used as the micropore-forming templates. Micropore-forming template/polymer blend membranes comprising organic micropore-forming templates embedded in a polymer matrix were prepared by dissolving the organic micropore-forming templates in the polymer solution followed by solution-casting and solvent evaporation or solvent exchange. Low-temperature selectively pyrolyzing micropore-forming templates in the micropore-forming template/polymer blend membranes at a nitrogen flow resulted in the formation of flexible microporous partially pyrolyzed polymeric membranes.

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.

摘要： The present invention discloses mixed matrix membranes (MMMs) comprising a polymer matrix and molecular sieve particles and methods for making and using these membranes. The molecular sieve particles contain micropores or mesopores and exhibit a thin plate morphology with high aspect ratio and the plate thickness no more than 300 nm. This invention also pertains to controlling the alignment of the thin plate molecular sieve particles in the continuous polymer matrix of the thin dense selective layer of the asymmetric mixed matrix membranes. These MMMs exhibited much higher selectivity improvement than those comprising molecular sieve particles with other kinds of morphology for gas separations such as CO2/CH4 and H2/CH4 separations. The thin plate morphology of molecular sieves is beneficial to make high performance mixed matrix membranes. The MMMs are suitable for a variety of liquid, gas, and vapor separations

摘要： The present invention discloses microporous aluminophosphate (AlPO4) molecular sieve membranes and methods for making and using the same. The microporous AlPO4 molecular sieve membranes, particularly small pore microporous AlPO-14 and AlPO-18 molecular sieve membranes, are prepared by three different methods, including in-situ crystallization of a layer of AlPO4 molecular sieve crystals on a porous membrane support, coating a layer of polymer-bound AlPO4 molecular sieve crystals on a porous membrane support, and a seeding method by in-situ crystallization of a continuous second layer of AlPO4 molecular sieve crystals on a seed layer of AlPO4 molecular sieve crystals supported on a porous membrane support. The microporous AlPO4 molecular sieve membranes have superior thermal and chemical stability, good erosion resistance, high CO2 plasticization resistance, and significantly improved selectivity over polymer membranes for gas and liquid separations, including carbon dioxide/methane (CO2/CH4), carbon dioxide/nitrogen (CO2/N2), and hydrogen/methane (H2/CH4) separations.

摘要： The present invention is for a polymer/polymer mixed matrix membrane and the use of such membranes in gas separation applications. More specifically, the invention involves the preparation of polymer/polymer mixed matrix membranes incorporating soluble polymers of intrinsic microporosity as microporous fillers. These polymeric fillers of intrinsic microporosity exhibit behavior analogous to that of conventional microporous materials including large and accessible surface areas, interconnected micropores of less than 2 nm in size, as well as high chemical and thermal stability, but, in addition, possess properties of conventional polymers including good solubility and easy processability. Gas separation experiments on these mixed matrix membranes show dramatically enhanced gas separation performance for CO2 removal from natural gas. Mixed matrix membranes prepared in accordance with the present invention can also be used in the separation of the following pairs of gases: hydrogen/methane, carbon dioxide/nitrogen, methane/nitrogen and olefin/paraffin such as propylene/propane.

摘要： A series of crystalline layered and microporous compositions have been prepared. Compositions that have a layered structure and are identified as UZM-13, UZM-17 and UZM-19. Upon calcination at a temperature of about 400° C. to about 600° C., these compositions form a microporous crystalline zeolite with a three dimensional framework which has been identified as UZM-25. A process for preparing all these compositions and processes for using these compositions are also disclosed.
