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.
