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. Olson, John Henry Pavlish, Michael J. Holmes

Patent number: 10589225Abstract: A promoted activated carbon sorbent is described that is highly effective for the removal of mercury from flue gas streams. The sorbent comprises a new modified carbon form containing reactive forms of halogen and halides. Optional components may be added to increase reactivity and mercury capacity. These may be added directly with the sorbent, or to the flue gas to enhance sorbent performance and/or mercury capture. Mercury removal efficiencies obtained exceed conventional methods. The sorbent can be regenerated and reused. Sorbent treatment and preparation methods are also described. New methods for in-flight preparation, introduction, and control of the active sorbent into the mercury contaminated gas stream are described.Type: GrantFiled: May 14, 2015Date of Patent: March 17, 2020Assignee: Midwest Energy Emissions Corp.Inventors: Edwin S. Olson, Michael J. Holmes, John Henry Pavlish

Patent number: 10471412Abstract: The present invention relates to activated carbon sorbents including nitrogen. In various embodiments, the present invention provides an activated carbon sorbent including a halogen- or halide-promoted activated carbon, the activated carbon sorbent particles including nitrogen in a surface layer of the sorbent particles. In various embodiments, the present invention provides a method of reducing the pollutant content in a pollutant-containing gas using the activated carbon sorbent. In various embodiments, the activated carbon sorbent can remove mercury from a mercury-containing gas that includes sulfur(VI) such as SO3 more efficiently than other sorbents.Type: GrantFiled: May 8, 2017Date of Patent: November 12, 2019Assignee: Midwest Energy Emissions Corp.Inventors: Edwin S. Olson, John Henry Pavlish
