摘要:
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.

摘要:
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.
摘要:
Disclosed herein, without limitation, are activated carbon honeycomb catalyst beds and systems for removing mercury and other toxic metals from a process stream, i.e, from flue gas of a coal combustion system. The activated carbon honeycomb can for example remove greater than 90% mercury from flue gas with a simple design and without adding material to the flue gas. Also disclosed herein, and without limitation, are methods for manufacturing and using the disclosed honeycomb catalyst beds and systems.

Plate systems and methods of using them. The plate systems may be used, for example, for the removal of metallic or semi-metallic contaminants from a fluid stream.
摘要:
Disclosed are methods and systems for regenerating mercury loaded activated carbon honeycomb catalyst beds. In one embodiment, the regeneration methods and systems disclosed herein can enable a more efficient and economical operation of a honeycomb based mercury removal system by, for example, allowing the reuse of a particular substrate multiple times.
