Abstract: Sorbent bodies comprising activated carbon, processes for making them, and methods of using them. The sorbent bodies can be used to remove toxic elements from a fluid, such as from a gas stream. For instance, the sorbent bodies may be used to remove elemental mercury or mercury in an oxidized state from a coal combustion flue gas.

Abstract: Sorbents comprising activated carbon particles, sulfur, and metal catalyst. The sorbents may be used, for example, for the removal of a contaminant, such as mercury, from a fluid stream.

Abstract: A flow-through sorbent comprising at least 30 wt % of a metal sulfide, and a binder. The sorbent may be used, for example, for the removal of a contaminant, such as mercury, from a fluid stream.

Abstract: A sorbent body adapted for abating toxic elements from a fluid stream, such as a carbon combustion flue gas stream or a syngas stream produced in coal gasification process, and process for making such sorbent. The sorbent body comprises an activated carbon matrix defining a plurality of pores, sulfur and an additive adapted for promoting the abatement of toxic elements from the fluid stream. At least one of the additive is formed into the sorbent body by in-situ forming such as in-situ extrusion. The sorbent is useful for abatement of, e.g., arsenic, cadmium, mercury and selenium from gas streams.

Abstract: A process for removing at least one of As, Cd, Hg and Se from a fluid stream, comprising: (I) providing a plurality of Group A particles of a Group A sorbent material, said Group A sorbent material comprising: an activated carbon matrix defining a plurality of pores; sulfur; and an additive adapted for promoting the removal of at least one of As, Cd, Hg and Se from a fluid stream, wherein the additive is distributed throughout the activated carbon matrix; and (II) contacting the fluid stream with a plurality of Group A particles of the Group A sorbent material. The process can involve powder injection, a packed sorbent bed, a fluidized sorbent bed, and combinations thereof.

Abstract: A composite comprising an inorganic substrate with a coating comprising activated carbon and a metal sulfide. The composite may be used, for example, for the removal of a contaminant, such as mercury, from a fluid stream.

Abstract: Methods of disposing of sorbent bodies comprising at least one toxic element which is substantially prevented from leaching into the surrounding environment are disclosed. The at least one toxic element which is prevented from leaching into the surrounding environment may include, for example, mercury, selenium, or both. The methods of disposing of said sorbent bodies may include, for example, depositing the sorbent bodies in a landfill. Landfill-disposable sorbent bodies which are configured to substantially prevent leaching into the surrounding environment of at least one toxic element are also disclosed.
