Abstract: The present disclose is directed to a method for controlling iodine levels in wet scrubbers, and, in particular, recirculating wet scrubbers by removing the iodine from the scrubbing solution, such as by using ion exchange, absorption, adsorption, precipitation, filtration, solvent extraction, ion pair extraction, and an aqueous two-phase extraction.

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 high energy/power density, long cycle life and safe lithium ion cell capable of long-term deep discharge/storage near zero-volt is described. The cell utilizes a near zero-volt storage capable anode, such as a spinel Li4Ti5O12, coupled to a high voltage, high-energy and/or high-power density cathode, such as LiNi0.5Mn1.5O4. The near zero-volt storage cell is rechargeable and affords safety advantages for battery transportation, storage, and handling, and significant cost reductions for cell maintenance. The cells produce high-energy and/or high-power densities and long cycle life. The cell anode, cathode, and separator active materials are coated with one or more protection or stability enhancing and/or conductivity enhancing materials to enhance electrochemical performance and to strengthen stabilities for long-term cycle life and storage life.
Abstract: Sorbent compositions that include a base sorbent material having a high porosity and surface area and a boron-selective agent are particularly useful for the sequestration of boron from waste materials such as coal combustion residual leachate (CCRs). By using a boron-selective agent in conjunction with a high surface area base sorbent material such as activated carbon or biochar, a sorbent composition with a high capacity for sequestering boron at relatively low cost is provided.

Abstract: An auxiliary spare tire brake light is provided for a vehicle having a spare tire with a rim that has spokes and openings and that is secured on lugs at the back of the vehicle. The auxiliary spare tire brake light includes a support disc having a central portion and a peripheral portion. An array of openings is formed in the central portion of the support disc and the openings are positioned to fit over the lugs at the back of the vehicle for positioning the support on the lugs behind the rim of the spare tire. An annular race extends around the peripheral portion of the support and a plurality of lights in the form of LEDs is disposed in the race. The LEDs are arrayed in a closely spaced substantially continuous array around the support to form a ring of LEDs.
Abstract: A composition is provided that includes a carbonaceous feed material to be combusted to generate an off-gas and an identifier. The identifier is associated with a predetermined composition, characteristic or property of the feed material or the off-gas.
Abstract: A composition of matter includes a mixture of styrene derivative monomers and methacrylate/acrylate derivative monomers, which form hydrogen bonds between/among different precursors, and initiators, and the compositions are used to achieve composition control of the forming polymer, with the mole fraction of acrylate/methacrylate and styrene moieties in the forming polymer determined preferably by the monomer reactivity and monomer composition rather than the viscosity of the monomers.
Abstract: Methods for the manufacture of sorbent compositions, sorbent compositions and methods for using the sorbent compositions. The methods include the utilization of an acidic halogen solution as a source of a halogen species that is dispersed on a solid sorbent. The use of the acidic halogen solution results in a highly active halogen species that demonstrates improved efficacy for the removal of heavy metal(s) from a flue gas. The sorbent composition includes a substantially amorphous halogen species associated with a solid sorbent such as powdered activated carbon (PAC).

Abstract: A composition of matter includes one or more functionalized vinylbenzyl components of the formula covalently connected to one or more R functional components; the one or more R functional groups selected from a group including one or more hydroxyl methyl (—CHOH—) moieties and/or derivatives thereof, one or more ethoxy (—CH2—CH2—O—) moieties and/or derivatives thereof, end one or more benzene (C6H6) and/or derivatives thereof; and ether links that connect the functionalized vinylbenzyl components and the R functional components.
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 mineral or graphite.
