The inorganic metal salt includes magnesium oxide, calcium oxide or combinations thereof. The medium has from about 0.1 to about 25% by weight of impregnate. The impregnate contains from about 0.1 to about 5% by weight organic amine, and the organic amine includes aqueous urea, solid urea, melamine or mixtures thereof. The impregnate contains from about 0.1 to about 5% by weight metal salt. The impregnate optionally further includes a surfactant such as polyacrylic acid. In some embodiments, the method includes removing at least two contaminants from the fluid stream.Type: GrantFiled: August 17, 2012Date of Patent: April 16, 2013Assignee: Purafil, Inc.Inventor: William G.

Patent number: 8404609Abstract: A method of forming functionalized fly ash particles includes contacting a plurality of fly ash particles with a hydroxide compound under conditions to directly bond oxygen (O) onto a surface portion of the plurality of fly ash particles. The plurality of fly ash particles having O directly bound to their surface portion are reacted with an organic alcohol or an organic acid to covalently bond hydrophobic groups in the form of condensation residue from the organic alcohol or organic acid to the O to form the plurality of functionalized fly ash particles.Type: GrantFiled: October 19, 2012Date of Patent: March 26, 2013Assignee: University of Central Florida Research Foundation, Inc.Inventors: Sudipta Seal, David L. Reid, Larry L. Hench

Publication number: 20130053234Abstract: A method for preparing a sorbent composition includes the steps of: (i) applying, from a solution or a slurry, a layer of a copper compound on the surface of a support material, and (ii) drying the coated support material, wherein the thickness of the copper compound layer on the dried support is in the range 1-200 ?m. The precursor may be converted to a sorbent suitable for removing heavy metals from liquids or gases by applying one or more sulphur compounds to sulphide the copper compound and form CuS.Type: ApplicationFiled: August 10, 2010Publication date: February 28, 2013Applicant: JOHNSON MATTHEY PLCInventors: Andrew Fish, Lucy Jane Challis, Matthew John Cousins, Mark Robert Feaviour, Alison Mary Wagland, Stephen David Pollington, Edmund Hugh Stitt

Publication number: 20130012753Abstract: Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste.Type: ApplicationFiled: September 14, 2012Publication date: January 10, 2013Applicant: Utter Technology, LLCInventor: Terry D.
