Abstract:
1. A sorbent composition for removal of mercury from a flue gas, the sorbent composition comprising: one or more bromides of a nonoxidative metal dispersed on porous particles, wherein the nonoxidative metal is selected from the group consisting of sodium, potassium, calcium, magnesium, and combinations thereof, and wherein the one or more bromides are dispersed on the porous particles according to a drying process; and a flow modifier physically blended with the porous particles in an amount sufficient to reduce agglomeration of the porous particles when injected into the flue gas, wherein the porous particles are selected from the group consisting of alumina, silica, titania, zirconia, iron oxides, zinc oxide, rare earth oxides, metal carbonate, metal sulfate, aluminosilicates, zeolites, clays, heat-treated clays, chemical-surface modified clays, talc, fly ash, fluid cracking catalyst (FCC) particles, dirt, and combinations thereof.
