Publication number: 20210170332Abstract: A promoted carbon and/or non-carbon base sorbent are described that are highly effective for the removal of mercury from flue gas streams. The promoted sorbent comprises a carbon and/or non-carbon base sorbent that has reacted with and contains forms of halogen and halides. Optional components may be added to increase and/or preserve reactivity and mercury capacity. These may be added directly with the base sorbent, or in-flight within a gas stream (air, flue gas, etc.), to enhance base sorbent performance and/or mercury capture. Mercury removal efficiencies obtained exceed conventional methods. The promoted sorbent can be regenerated and reused. Base sorbent treatment and preparation methods are also described. New methods for in-flight preparation, introduction, and control of the active base sorbent into the mercury contaminated gas stream are described.Type: ApplicationFiled: August 14, 2020Publication date: June 10, 2021Inventors: Edwin S. Olson, Michael J. Holmes, John H. Pavlish

Patent number: 10828596Abstract: Promoted ammonium salt-protected activated carbon sorbent particles for removal of mercury from gas streams. A method of separating mercury from a mercury-containing gas stream includes contacting a mercury-containing gas stream with an activated carbon sorbent including promoted ammonium salt-protected activated carbon sorbent particles, to form a mercury-sorbent composition. The method also includes separating at least some of the mercury-sorbent composition from the mercury-containing gas stream, to give a separated gas.Type: GrantFiled: December 16, 2016Date of Patent: November 10, 2020Assignee: Midwest Energy Emissions Corp.Inventors: Edwin S.
