Abstract
A flue gas adsorbent and method for making an adsorbent for mercury capture are disclosed. The adsorbent comprises an admixture of an adsorptive material and an additive that have been physically combined thereby eliminating the need for traditional impregnation. A method for removing mercury from a flue gas stream is also disclosed.

A flue gas adsorbent comprising a dry admixture of a granular activated carbon capable of adsorbing mercury and a granular halide salt, wherein the admixture is in powdered form and wherein the granular halide salt is not disposed on or impregnated into the granular activated carbon.
A method for removing mercury from a flue gas stream comprising contacting the flue gas stream with a dry admixture, the dry admixture comprising a granular activated carbon capable of adsorbing mercury and a granular halide salt wherein the granular halide salt is not disposed on or impregnated into the dry activated carbon during the step of contacting the flue gas stream.
