    摘要： The present invention discloses a new class of high flux mixed matrix membranes that are made by incorporating porous inorganic fillers (e.g. microporous and mesoporous molecular sieves, carbon molecular sieves, porous metal-organic frameworks) into a high flux high surface area microporous organic polymer matrix. These microporous organic polymers are referred to as “polymers of intrinsic microporosity” or PIMs. The high flux membranes are promising for a wide range of separations including liquid separations such as pervaporation of phenol/water and also gas separations in the petrochemical, refinery, and natural gas industries such as methane/carbon dioxide, olefin/paraffin and iso/normal paraffins separations.

    摘要： A novel method of making an adsorptive membrane that incorporates super activated carbon particles in which the activated carbon particles that are incorporated within the membrane retain their highly adsorptive characteristics. In accordance with one form of the method of the invention, the multiplicity of small pores in the activated carbon particles are uniquely protected from becoming clogged during the process of forming the adsorptive membrane by initially wetting the particles with water prior to intermixing the particles with the hydrocarbon solvent solution of a polyurethane resin from which the membrane is formed.

    摘要： A device useful for separating the components of gas mixtures includes a selectively gas permeable mixed matrix membrane of a dispersed phase of chabazite type molecular sieve particles uniformly distributed throughout a continuous phase of a polymer. The membrane can be fabricated by dispersing the chabazite type molecular sieve particles in a solution of the polymer dissolved in a suitable solvent, and then forming the suspension into a membrane structure by conventional polymer membrane fabrication techniques. Mixed matrix membranes with chabazite type molecular sieves are well suited to separations of oxygen, carbon dioxide or helium from nitrogen or methane.
