    摘要: Nano-molecular sieve-polymer mixed matrix membranes (MMMs) for CO2 removal from natural gas have been prepared by incorporating dispersible template-free nano-molecular sieves into polymer matrices such as Matrimid 5218 polyimide matrix or Ultem 1000 polyetherimide matrix. The nano-molecular sieves used in this invention include template-free nano-AlPO-18, nano-AlPO-5, nano-Silicalite, nano-SAPO-34, and PEG-functionalized nano-Silicalite. These template-free nano-molecular sieves were synthesized by an organic ligand grafting method.

    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.

    摘要: This invention discloses a composition of, a method of making, and an application of high plasticization-resistant chemically cross-linked organic-inorganic hybrid membranes such as cross-linked cellulose acetate-cellulose triacetate-polyurethanepropylsilsesquioxane membranes. These cross-linked membranes with covalently interpolymer-chain-connected hybrid networks were prepared via a sol-gel condensation polymerization of cross-linkable organic polymer-organosilicon alkoxide precursor membrane materials. CO2 plasticization tests on these cross-linked membranes demonstrate extremely high CO2 plasticization resistance under CO2 pressure up to 5516 kPa (800 psig). These new cross-linked membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as desalination.

    摘要: A process for producing an ElAPO molecular sieve with essentially pure CHA framework having an average crystal size less than about 5 micrometers is disclosed. When El is silicon, the process allows for a broad range of silicon content, and produces a catalyst with a high selectivity for the conversion of methanol to olefins. The process includes making a crystalline metallo-aluminophosphate molecular sieve of the formula (ElxAlyPz)O2from a mixture comprising an aluminum source, a phosphorous source, water, an El source, a fluorine source and an organic template source wherein the molar ratio of the organic template source to phosphorous is less than about 0.5; crystallizing the molecular sieve at a temperature between 100 C and 250 C and calcining in air.

    摘要: A process for forming a zeolite beta dielectric layer onto a substrate such as a silicon wafer has been developed. The zeolite beta is characterized in that it has an aluminum concentration from about 0.1 to about 2.0 wt. %, and has crystallites from about 5 to about 40 nanometers. The process involves first dealuminating a starting zeolite beta, then preparing a slurry of the dealuminated zeolite beta followed by coating a substrate, e.g. silicon wafer with the slurry, heating to form a zeolite beta film and treating the zeolite beta with a silylating agent.

    摘要: The present invention discloses an approach for making mixed matrix membranes (MMMS) and methods for using these membranes. These MMMs contain a continuous polymer matrix and dispersed microporous molecular sieve particles. This invention also pertains to control of the thickness of the thin dense selective mixed matrix membrane layer that is equal to or greater than the particle size of the largest molecular sieve particles for making large scale asymmetric MMMs. In particular, the invention is directed to making asymmetric flat sheet MMM by a phase inversion technique. The MMMs of the present invention exhibit at least 20% increase in selectivity compared to the polymer membranes prepared from their corresponding continuous polymer matrices. The MMMs of the present invention are suitable for a variety of liquid, gas, and vapor separations.
