Abstract: A sorbent composition for enhanced baghouse function is described. The composition may include a sorbent such as powder activated carbon as well as an additive that is a heat moderator or a permeability agent. The heat moderator may act as a heat sink or barrier. Heat moderators may include in non-limiting examples phyllosilicates, cyclosilicates, or nesosilicates that may include, montmorillonite, bentonite, halloysite, aluminum silicates, muscovite, illite, kaolin, andalusite, kyanite, sillimanite, metakaolin, mullite, polymers, such as chitosan, and/or clays, either natural or synthetic (e.g., montmorillonite), or polyethylenimine. Permeability may be affected by mixing sorbents of lower D50 with sorbents of higher D50 in various ratios, or addition of a permeability agent such as a phyllosilicate, perlite, silica, diatomaceous earth. Further, a permeability agent such as a fluoropolymer may be coated onto or admixed with the sorbent.

Abstract: A sorbent composition such as for the removal of a contaminant species from a fluid stream, a method for manufacturing a sorbent composition and a method for the treatment of a flue gas stream to remove heavy metals such as mercury (Hg) therefrom. The sorbent composition includes a porous carbonaceous sorbent such as powdered activated carbon (PAC) and a solid particulate additive that functions as a flow-aid to enhance the pneumatic conveyance properties of the sorbent composition. The solid particulate additive may be a flake-like material, for example a phyllosilicate minerals or graphites.

Abstract: Sorbent compositions, comprising a solid sorbent, a dispersive agent, and optionally a capture agent for enhanced wet-Flue Gas Desulfurization (wFGD) or wet scrubber unit function in a flue gas pollutant control stream is disclosed. The sorbent composition may include a sorbent with a dispersive agent, designed to enhance the dispersion of the sorbent in an aqueous sorption liquid of a wet scrubber unit, and therefore may be especially useful in EGU or industrial boiler flue gas streams that include one or more wet scrubber units. The sorbent composition may also include a capture agent useful in sequestering mercury and bromine, as well as other contaminants that may include arsenic, selenium and nitrates.

Abstract: A sorbent composition that is useful for injection into a flue gas stream of a coal burning furnace to efficiently remove mercury from the flue gas stream. The sorbent composition may include a sorbent with an associated ancillary catalyst component that is a catalytic metal, a precursor to a catalytic metal, a catalytic metal compound or a precursor to a catalytic metal compound. Alternatively, a catalytic metal or metal compound, or their precursors, may be admixed with the coal feedstock prior to or during combustion in the furnace, or may be independently injected into a flue gas stream. A catalytic promoter may also be used to enhance the performance of the catalytic metal or metal compound.

Abstract: A multi-functional composition of matter that is useful for injection into a flue gas stream to rapidly and efficiently remove mercury from the flue gas streams, particularly at above average flue stream temperatures of about 340° F. or higher. The multi-functional composition of matter may include a fixed carbon content of at least about 20 wt. %, a mineral content of from about 20 wt. % to about 50 wt. %, a sum of micropore plus mesopore volume of at least about 0.20 cc/g, a micropore volume to mesopore volume ratio of at least about 0.7, and a tapped density of not greater than about 0.575 g/ml. These compositions may be further characterized by number of particles per gram of the composition of matter such that the composition may have at least about 0.8 billion particles per gram, or even as many as 1.5 billion particles per gram.

Abstract: Compositions and method useful for removal of mercury from a flue gas stream with relatively high concentrations of acid gas precursors and/or acid gases. The method includes contacting the flue gas stream with a sorbent composition comprising a sorbent material and a multi-functional agent, where the multi-functional agent includes a compound having a metal of valency 3 or higher. The multi-functional agent may be an inorganic salt, wherein either the cation or anion of the salt comprises a metal selected from Group 3 to 14 metal, such as aluminum. A halogen such as in the form of a halide salt that helps facilitate the oxidation of elemental mercury into its oxidized form may be present in the sorbent composition.

Abstract: Method and compositions useful for removal of mercury from a flue gas stream with relatively high concentrations of acid gas precursors and/or acid gases. The method includes contacting the flue gas stream with a multi-functional agent, where the multi-functional agent includes a salt having a cation of valency 3 or higher. A composition comprises a (1) sorbent material such as powdered activated carbon which will ultimately capture and sequester oxidized mercury, (2) a multi-functional agent that protects the sorbent core from unfavorable reaction conditions or inhibitors, oxidizes or helps catalyze the oxidation of elemental mercury, and/or amalgamates with elemental mercury to make it easier to capture, among other benefits, and optionally (3) a halogen such as in the form of a halide salt that helps facilitate the oxidation of elemental mercury into its oxidized form.

Abstract: A process for deodorizing tall oil rosin and tall oil fatty acids and their derivatives by treating same with an ammonium hydroxide solution under conditions of a steam sparge.

Abstract: Granular detergent compositions contain a low level of ammonium salt or salt of specific anion chlorine scavenger which is preferably protected in a particle. Such salts protect enzymes in the wash process. The preferred particles can also comprise, e.g., a suds-controlling silicone material which is substantially removed from contact with the surfactant component or alkaline component of the composition. The particles preferably use, e.g., a polyethylene glycol carrier, with preferably a small amount of fatty acid, in an irregularly shaped particle having a minimum dimension of at least about 0.05 cm.
