摘要： A polyimide MMC membrane useful for the production of oxygen-enriched air or nitrogen-enriched-air, for the separation of carbon dioxide from hydrocarbons or nitrogen, and the separation of helium or hydrogen from various streams. Membranes of polyimide polymers, such as polyimide polymers sold under the tradename P-84, are mixed with molecular sieve materials, such as SSZ-13, to make MMC membranes. The MMC membranes of the invention provide improved membrane performance compared to polymer only membranes, particularly when used to form asymmetric film membranes or hollow fiber membranes. The MMC films exhibit consistent permeation performance as dense film or asymmetric membranes, and do not interact with components of the process streams, such as organic solvents. The membranes of the invention exhibit particularly surprisingly good selectivity for the fluids of interest.

摘要： Isopycnic or asymmetric mixed matrix hollow fiber membranes for gas separation can be made by a continuous spinning process. Mixed matrix membranes are characterized by a continuous phase of selectively gas permeable polymer in which are uniformly dispersed discrete absorbent particles such as molecular sieves that also have selectivity enhancing properties. The fibers can be monolithic in which the fiber wall is entirely mixed matrix, or composite in which an active mixed matrix layer is positioned adjacent to a supporting substrate layer. The novel mixed matrix hollow fiber membranes provide higher selectivity than dense film membranes of the continuous phase polymer.

摘要： A mixed matrix membrane for gas separations is provided with a nonporous continuous phase of a polymer and a dispersed phase of molecular sieve particles reacted with a monofunctional organosilicon compound. The monofunctional organosilicon compound is characterized by (a) at least one silicon substituent group which reacts or is compatible with the polymer, and (b) at most one displaceable radical that can react with the molecular sieve. A process for making a selectively gas permeable mixed matrix membrane involves reacting a molecular sieve with the monofunctional organosilicon compound, uniformly dispersing the reacted sieve with a polymer, and forming the resulting mixed matrix composition into a membrane structure. These mixed matrix membranes provide an improved combination of permeability and selectivity as compared to polymer-only membranes and mixed matrix membranes in which the molecular sieve is not reacted with a monofunctional organosilicon compound.

摘要： Heavy crude oils which contain metal contaminants such as nickel, vanadium and iron may be separated from light hydrocarbon oils by passing a solution of the crude oil dissolved in a cycloparaffinic hydrocarbon solvent containing from about 5 to about 8 carbon atoms by passing through a polymeric membrane which is capable of maintaining its integrity in the presence of hydrocarbon compounds. The light hydrocarbon oils which possess relatively low molecular weights will be recovered as the permeate while the heavy oils which possess relatively high molecular weights as well as the metal contaminants will be recovered as the retentate.

摘要： A process for separating a monosaccharide from an aqueous solution comprising monosaccharides and a second component comprising a polysaccharide. The mixture is contacted with a mixed matrix membrane comprising a adsorbent or molecular sieve material dispersed in an organic polymer in which the monosaccharide has a greater steady state permeability than the polysaccharide. The monosaccharide passes through the membrane, and is recovered. Particular mixed matrix membranes found to be useful in separating mono from polysaccharides are silicalite, gamma-alumina, activated carbon or a calcium exchanged Y-zeolite dispersed in cellulose acetate or polyelectrolyte complex polymers.
