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 Hue 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 SO

Abstract: A method of preparing a mercury sorbent material comprising making a copper/clay mixture by admixing a dry clay and a dry copper source; making a sulfur/clay mixture by admixing a dry clay and a dry sulfur source; admixing the copper/clay mixture and the sulfur/clay mixture, to form a mercury sorbent pre-mixture; and shearing the mercury sorbent pre-mixture to form the mercury sorbent material. The mercury sorbent material has an interlayer d(001)- spacing of less than 12 A when the mercury sorbent material contains less than 4 wt % water, and a powder X-ray diffraction pattern of the mercury sorbent material is substantially free of a diffraction peak at 2.73 + 0.01 A, and the ζ-potential of the mercury sorbent material is greater than the ζ -potential of the dry clay.

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 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 SO 2 , SO 3 , 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. The method of entombing mercury includes mixing the collected mixture with water to form a freshly mixed concrete; and casting the freshly mixed concrete into a form.
