Patent ID: 8652235

Claim:
A method for separating mercury from a mercury containing gas comprising: (a) providing a carbon sorbent material and a non-carbon sorbent material, wherein the carbon sorbent material comprises activated carbon; (b) providing a halogen or halide promoter; (c) promoting at least a portion of the carbon sorbent material and the non-carbon sorbent material by chemically reacting the carbon sorbent material and the non-carbon sorbent material with the halogen or halide promoter to form a promoted halogenated carbon sorbent and a promoted halogenated non-carbon sorbent; (d) chemically reacting elemental mercury in the mercury containing gas with the promoted halogenated carbon sorbent and the promoted halogenated non-carbon sorbent to form a mercury/sorbent chemical composition; and (e) separating particulates from the mercury containing gas to form a cleaned gas, the particulates including ash and the mercury/sorbent chemical composition.
