  • Patent number: 8420561
    Abstract: Herein is disclosed a flue gas scrubbing composition, a method of using the flue gas scrubbing composition, and a method of entombing mercury collected with the flue gas scrubbing composition. The flue gas scrubbing composition includes an admixture of a mercury sorbent material that comprises a clay, copper, and sulfur; and lime that comprises calcium oxide and/or calcium hydroxide. The method of collecting mercury from a flue gas includes injecting the flue gas scrubbing composition of any one of the preceding claims into a flue duct comprising the flue gas; reacting the mercury sorbent material with mercury in the flue gas to form a mercury-sorbed material and thereby reducing the concentration of mercury in the flue gas; reacting the lime with SO2, SO3, and/or HCl in the flue gas to form a calcium sulfate and/or a calcium chloride; and collecting a mixture that includes the mercury-sorbed material.

  • Patent number: RE44124
    Abstract: A regenerable, high-capacity sorbent for removal of mercury from flue gas and processes and systems for making and using the sorbent. A phyllosilicate substrate, for example vermiculite or montmorillinite, acts as an inexpensive support to a thin layer for a polyvalent metal sulfide, ensuring that more of the metal sulfide is engaged in the sorption process. The sorbent is prepared by ion exchange between the silicate substrate material and a solution containing one or more of a group of polyvalent metals including tin (both Sn(II) and Sn(IV)), iron (both Fe(II) and Fe(III)), titanium, manganese, zirconium and molybdenum, dissolved as salts, to produce an exchanged substrate. Controlled reaction of a sulfide ion source with the one or more polyvalent metals that are exchanged on the silicate substrate produces the sorbent. The sorbent is used to absorb elemental mercury or oxidized mercury species such as mercuric chloride from flue gas containing acid gases (e.g.
