摘要： A method and apparatus is provided for regenerating a sorbent that has been poisoned by components derived from flue gas. The sorbent is treated with an agent to remove the poisoning components and introduce a promoting agent into the sorbent. The method and apparatus can also be used to enhance the effectiveness of a new sorbent.

摘要： 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.

摘要： 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.

摘要： A system and method is provided for the removal of mercury from flue gas. Effective removal of mercury is obtained by oxidation of elemental mercury, with highly reactive halogen species derived from dissociation of halogen compounds at moderate temperatures brought into contact with the flue gas with or without the addition of carbon.

摘要： 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.
