    Abstract: A process and apparatus to remove and breakdown volatile organic compounds from drinking water, groundwater, wastewater, frack water and air exhaust. The process entails filling a tank, chamber, pipe, or column with ozone-containing gas, introducing into this ozone-containing gas-filled tank, chamber, pipe or column, very small droplets of water, contaminated with volatile organic compounds which then volatilize out from the water and break down in the ozone gas thereby improving the water quality and associated air quality. The current invention has been shown to achieve more than 99% combined removal efficiency. The process can also be used to treat air streams containing volatile organic compounds. To increase efficiency, ozone is introduced where the atomized particles are smallest. Three configurations utilizing said process include upward and downward spray of contaminated water into ozone and pumping through openings in an enclosure to a reaction chamber filled with ozone-containing gas.

  • Publication number: 20140079617
    Abstract: An apparatus for treating a gas stream comprises a nonthermal plasma reactor, for example a dielectric barrier discharge plasma reactor, containing a silicon-containing solid for reacting with a halogen-containing component of the gas stream to form a gaseous silicon halide. A sorbent bed of material chosen to react with the silicon halide to form inorganic halides is located downstream from the plasma reactor. A similar bed of material is located upstream from the plasma reactor to remove silicon halide and other acid gas components from the gas stream before it enters the plasma reactor.

  • Publication number: 20140072495
    Abstract: The invention relates to a hybrid reverse flow catalytic apparatus having two reaction zones: a homogeneous reaction zone in porous ceramic and a heterogeneous reaction zone with catalyst, arranged in two different catalyst beds. A first catalytic bed located in a central region of the reactor is provided with a low activity catalyst and a second catalyst bed located in a peripheral region of the reactor is provided with a high activity catalyst. The provision of two catalyst beds containing different catalysts reduces the effect of radial temperature gradients in the reactor and improves the overall efficiency of the reactor. The invention also relates to method of performing catalytic and thermochemical reactions in said apparatus.

  • Publication number: 20140061540
    Abstract: Metal-organic frameworks of the family M2 (2,5-dioxido-1,4-benzenedicarboxylate) wherein M=Mg, Mn, Fe, Co, Cu, Ni or Zn are a group of porous crystalline materials formed of metal cations or clusters joined by multitopic organic linkers that can be used to isolate individual gases from a stream of combined gases. This group of adsorbant materials incorporates a high density of coordinatively-unsaturated MII centers lining the pore surfaces. These adsorbents are particularly suited for selective carbon dioxide/monoxide adsorption via pressure swing adsorption near temperatures of 313 K since they selectively adsorb carbon dioxide at high pressures in the presence of hydrogen, and desorb carbon dioxide upon a pressure decrease. The redox-active FeII centers in Fe2(dobdc) can be used for the separation of O2 from N2 and other separations based on selective, reversible electron transfer reactions.

  • Patent number: 8658118
    Abstract: An object of the present invention is to provide more inexpensive high purity crystalline silicon which can satisfy not only a quality required to a raw material of silicon for a solar cell but also a part of a quality required to silicon for an up-to-date semiconductor and a production process for the same and provide high purity silicon tetrachloride used for production of high purity crystalline silicon and a production process for the same. The high purity crystalline silicon of the present invention has a boron content of 0.015 ppmw or less and a zinc content of 50 to 1000 ppbw. The production process for high purity crystalline silicon according to the present invention is characterized by that a silicon tetrachloride gas and a zinc gas are supplied to a vertical reactor to react them at 800 to 1200° C.

  • Patent number: 8640440
    Abstract: Disclosed herein is a catalytically active particulate filter, an exhaust gas cleaning system and a process for cleaning the exhaust gases of predominantly stoichiometrically operated internal combustion engines, which are suitable, as well as the gaseous CO, HC and NOx pollutants, also for removing particulates from the exhaust gas. The particulate filter comprises a filter body and a catalytically active coating consisting of two layers. The first layer is in contact with the incoming exhaust gas, the second layer with the outgoing exhaust gas. Both layers contain alumina. The first layer contains palladium. The second layer contains, in addition to rhodium, an oxygen-storing cerium/zirconium mixed oxide.

  • Publication number: 20140030179
    Abstract: An article and method for degrading volatile organic compounds in an electronic enclosure is disclosed. The method comprises providing a substrate, such as a scrim material, and applying a catalyst to the substrate. The catalyst typically includes a base metal. The substrate and catalyst material are placed into a disk drive (or other electronic) enclosure where they help in degradation of organic compounds, in particular volatile organic compounds. In certain implementations the base metal is selected from the group of manganese, vanadium, nickel, copper, cobalt, chromium, iron, or combinations thereof.

  • Publication number: 20140005352
    Abstract: The invention relates to a method for producing a high molecular weight polyethylene terephthalate (PET) via a solid state polymerization system. The method comprises using an acid catalyst to effectuate the conversion of acetaldehyde present within the system to 2-methyl-1,3-dioxolane, which can be readily removed. The invention also relates to PET prepared via this process, which can advantageously exhibit low levels of acetaldehyde.
