  • Use Of Mgo Doped With A Divalent Or Trivalent Metal Cation For Removing Arsenic From Water

    view source
  • US Patent:
    8507004, Aug 13, 2013
  • Filed:
    Dec 17, 2008
  • Appl. No.:
    12/336953
  • Inventors:
    Robert C. Moore - Edgewood NM, US
    Ranko Bontchev - Albuquerque NM, US
  • Assignee:
    Sandia Corporation - Albuquerque NM
  • International Classification:
    B01J 20/04

    A61K 33/08
    A61K 33/30
    A61K 9/14
    A61P 1/00
  • US Classification:
    424489, 210688, 502414, 424692, 424641
  • Abstract:
    Systems and methods for use of magnesium hydroxide, either directly or through one or more precursors, doped with a divalent or trivalent metal cation, for removing arsenic from drinking water, including water distribution systems. In one embodiment, magnesium hydroxide, Mg(OH)(a strong adsorbent for arsenic) doped with a divalent or trivalent metal cation is used to adsorb arsenic. The complex consisting of arsenic adsorbed on Mg(OH)doped with a divalent or trivalent metal cation is subsequently removed from the water by conventional means, including filtration, settling, skimming, vortexing, centrifugation, magnetic separation, or other well-known separation systems. In another embodiment, magnesium oxide, MgO, is employed, which reacts with water to form Mg(OH). The resulting Mg(OH)doped with a divalent or trivalent metal cation, then adsorbs arsenic, as set forth above. The method can also be used to treat human or animal poisoning with arsenic.

  • Abstract:
    A process is described for producing a powder batch comprises a plurality of particles, wherein the particles include (a) a first catalytically active component comprising at least one transition metal or a compound thereof; (b) a second component different from said first component and capable of removing oxygen from, or releasing oxygen to, an exhaust gas stream; and (c) a third component different from said first and second components and comprising a refractory support. The process comprises providing a precursor medium comprising a liquid vehicle and a precursor to al least one of said components (a) to (c) and heating droplets of said precursor medium carried in a gas stream to remove at least part of the liquid vehicle and chemically convert said precursor to said at least one component.

  • US Classification:
    502304, 502339, 502333, 502328, 977773
  • Abstract:
    A catalyst composition comprises a particulate support and catalyst nanoparticles on the particulate support. The catalyst nanoparticles comprise an alloy of platinum and palladium in an atomic ratio of from about 25:75 to about 75:25 and are present in a concentration of between about 3 and about 10 wt % weight percent of the catalyst composition. The catalyst composition has an X-ray diffraction pattern that is substantially free of the (311) diffraction peak assignable to PtPd, where 0.25≦x≦0.75.
