    Abstract: A gas separation membrane for selective separation of hydrogen and helium from gas mixtures containing carbon dioxide includes a porous support layer, an aromatic polyamide layer on the porous support layer, and a coating including a glassy polymer formed on the aromatic polyamide layer. A glass transition temperature of the glassy polymer is greater than 50° C. The gas separation membrane may be formed by contacting a solution including the glassy polymer with an aromatic polyamide layer of a composite membrane and drying the solution to form a coating of the glassy polymer on the aromatic polyamide layer. Separating hydrogen or helium from a gas stream including carbon dioxide includes contacting a gas feed stream including carbon dioxide with the gas separation membrane to yield a permeate stream having a concentration of helium or hydrogen that exceeds the concentration of helium or hydrogen, respectively, in the gas feed stream.

    Abstract: The present invention relates to a method of treating a surface comprising a silicone elastomer having a plurality of Si—H groups by contacting at least one region of the surface with a solution comprising a surface treatment compound, to give a treated surface with Si—OH, Si—OR, or Si—C groups. The present invention relates to a hydrosilylation-curable silicone composition. In some examples, the hydrosilylation-curable silicone composition includes an organohydrogen-polysiloxane having an average of at least forty silicon-bonded hydrogen atoms per molecule, a cross-linking agent having an average of at least two aliphatic unsaturated carbon-carbon bonds per molecule, and a hydrosilylation catalyst, wherein the mole ratio of silicon-bonded hydrogen atoms in the composition to aliphatic unsaturated carbon-carbon bonds in the composition is at least 20:1. The invention also relates to membranes, methods of making membranes, gas permeable supports for membranes, and methods of gas separation using membranes.

  • Patent number: 8820312
    Abstract: The oxygen transport reactor-based oven is an oven for heating articles, such as bread, using oxygen transport reactor-based combustion in order to recycle carbon dioxide, rather than releasing the carbon dioxide into the environment. The oven includes an upper furnace chamber having a plurality of oxygen transport reactors disposed therein. A mixture of fuel and gaseous carbon dioxide is delivered to the interior of each oxygen transport reactor. Pressurized air is then delivered to the upper furnace chamber, so that oxygen from the pressurized air is driven through an ion transport membrane of each oxygen transport reactor to combust with the fuel. This combustion produces carbon dioxide, water vapor and heat. The generated heat is used to heat the articles to be heated, which are received within a heating chamber positioned beneath the upper furnace chamber.

  • Patent number: 8814983
    Abstract: The present disclosure is directed to a system for delivery of a target material and/or energy. The system includes a source configured to provide a mixture containing the target material and a non-target material, a delivery conduit coupled to the source to receive the mixture from the source, and an in-line extraction device concentric to the delivery conduit. The in-line extraction device is configured to selectively extract the target material and/or energy from the mixture in the delivery conduit and to delivery it to a downstream facility.

  • Patent number: 8771404
    Abstract: A composite hollow ceramic fiber includes a porous hollow core supporting a thin, dense sheath. The non-gas-tight core comprises a first ceramic material and an interconnecting network of pores. The gas-tight sheath comprises a second ceramic material. The fiber is made by extruding a core suspension of particles of the first ceramic material, a polymeric binder, and a solvent and a sheath suspension of particles of the second ceramic material, a polymeric binder and a solvent, respectively, from a spinnerette and coagulating the nascent hollow fiber to effect phase inversion of the polymeric binders. The resultant green fiber is sintered in a two step process. First, the binders are burned off. Second, the sheath is densified and the second ceramic material is sintered without fully sintering the first ceramic material. The first ceramic material of the core suspension has a median particle size greater than that of the second ceramic material of the sheath suspension.

  • Patent number: 8758489
    Abstract: A radial seal is described for use in a filtration system having annular elements. The rings or annuli fit in a groove in an outer surface of a seal plate. Each annulus has an outer diameter larger than the inner diameter of a cylindrical housing of the filtration system. A gap in the annulus has a width selected to enable the annular element to deform sufficiently to permit insertion of the at least one annulus into the cylindrical housing. Two or more annuli can be configured such that the gaps of the annuli are misaligned when both annuli are installed in the groove, thereby minimizing leakage in operation. A registration system includes a registration element that cooperates with a registration element of the other annulus to ensure misalignment of the gaps of the pair of annuli.
