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： 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： Mixed matrix composite (MMC) membranes with minimal macrovoids and defects are provided by the current invention. MMC Membranes are needed that have minimal macrovoids and defects, provide consistent and good selectivity and permeability performance, provide the mechanical strength required to withstand high membrane differential pressures, and exhibit sufficient flexibility and can easily be formed into desirable membrane forms. MMC Membranes made from a spinning dope that is stabilized with an electrostabilizing additive, particularly an acid additive, results in membranes, particularly hollow fiber membranes that have minimal macrovoids and defects. Thus, membranes of the current invention are particularly suitable for high trans-membrane pressure applications, particularly for separating oxygen/nitrogen, hydrogen/hydrocarbon, and carbon dioxide/hydrocarbon components of a stream.
