Publication number: 20200129924Abstract: 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.Type: ApplicationFiled: December 23, 2019Publication date: April 30, 2020Applicant: ADA CARBON SOLUTIONS, LLCInventors: Robert B.

Patent number: 10421037Abstract: 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.Type: GrantFiled: October 10, 2017Date of Patent: September 24, 2019Assignee: ADA Carbon Solutions, LLCInventors: Mowen Li, Robert B.

Patent number: 10159928Abstract: Sorbent compositions including sorbent particles of a small particle sized sorbent with increased pneumatic conveyance properties. The sorbent compositions have relatively small median particle size and have a controlled particle size distribution (PSD). Specifically, the sorbent compositions include a relatively small percentage of very fine particles, such as a small percentage of particles having a particle size of not greater than about 5 ?m. The sorbent compositions are particularly useful for the treatment of a flue gas stream to remove mercury from the flue gas stream.Type: GrantFiled: February 7, 2017Date of Patent: December 25, 2018Assignee: ADA Carbon Solutions, LLCInventors: Sarah G.
