  • Publication number: 20130047850
    Abstract: Effective synthesis gas purification is achieved by applying copper adsorbents which are resistant to the reduction by the components of the synthesis gas H2 and CO at normal operation conditions. The novel adsorbents are produced by admixing small amounts of an inorganic halide, such as NaCl, to the basic copper carbonate precursor followed by calcination at a temperature sufficient to decompose the carbonate. The introduction of the halide can be also achieved during the forming stage of adsorbent preparation. These reduction resistant copper oxides can be in the form of composites with alumina and are especially useful for purification of synthesis gas or gas streams containing hydrogen carbon monoxide or other reducing agents.

  • Patent number: 8231711
    Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.

    Abstract: A method and apparatus for simultaneously removing alkali chlorides from an industrial process and purifying vaporizable contaminants such as mercury from a particulate material. Gases containing alkali chlorides are cooled to a temperature above the boiling point of the contaminants and below the boiling point of the alkali chlorides. Particulates rich in alkali chlorides are removed from the gas stream with a first dust collector. The gas stream cleaned of alkali chlorides is directed to a reaction area where particulate material containing mercury contaminants is inserted into the gas stream to vaporize the contaminants from the material and entrain the cleaned material in the gases. The gases are directed to a second dust collector to remove the entrained particulate material, after which a sorbent or chemical reagent is injected in the gases to interact with the contaminants and form a contaminant containing product that is entrained in the gases and thereafter separated from the gases.

  • Publication number: 20120073439
    Abstract: Synthesis of a support material impregnated with silver sulfide provides a sorbent composition. Generating the silver sulfide relies on reaction of sulfur dioxide and one of hydrogen gas and hydrogen sulfide in presence of the support material following silver loading of the support material. Contacting a fluid stream with the sorbent composition removes heavy metal from the fluid stream.

  • Patent number: 8142549
    Abstract: A method of reducing moisture in a fluorine-containing gas is described. The method may include the steps of providing a purifier material that includes elemental carbon, and flowing the unpurified fluorine-containing gas having an unpurified moisture concentration over or through the carbon-based purifier material. At least a portion of the moisture is captured in the purifier material so that a purified fluorine-containing gas that emerges downstream of the purifier material has a reduced moisture concentration that is about 50% or less of the unpurified moisture concentration.

  • Patent number: 8137648
    Abstract: A diesel engine exhaust treatment system and method is provided which includes a platinum group metal trapping device (16) comprising cerium oxide or a perovskite material positioned between a diesel oxidation catalyst and an SCR catalyst. The platinum group metal trapping device traps trace amounts of platinum group metals which may be released from the diesel oxidation catalyst during engine operation and prevents them from accumulating on the SCR catalyst, preventing potential contamination of the SCR catalyst as well as ensuring that the performance of the SCR catalyst is uninhibited.

  • Patent number: 8118916
    Abstract: Metal ions are adsorbed or absorbed by a combination of a binding ligand and an ionic liquid effective to dissolve the metal complex. The ligand is preferably bound to a solid surface which is coated with the ionic liquid. This method is particularly suitable for adsorbing gaseous mercury, lead, zinc and cadmium.

  • Patent number: 8118913
    Abstract: A process and system for the purification of germane containing phosphine to provide a purified germane product. One aspect of the present invention is a process for making a purified germane product containing less than 50 ppb of phosphine which comprises providing a phosphine contaminated germane gas hydrogen gas mixture; passing the germane gas hydrogen gas mixture through an adsorbent which selectively adsorbs phosphine and withdrawing therefrom a purified germane gas hydrogen mixture; and separating the purified germane gas from the hydrogen germane gas mixture.

  • Publication number: 20110319697
    Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.
