Patent ID: 8609580

Claim:
A method of making catalytic adsorbent for use in the adsorption of mercury from flue gas streams at elevated temperatures, comprising: injecting a presoaked carbonaceous feedstock into a reaction chamber wherein the presoaked carbonaceous feedstock is manufactured by presoaking a prepulvurized carbonaceous feedstock in powder form in a solution selected from the group consisting of aqueous and alcohol salt solutions wherein the salt is selected from the group consisting of alkali, alkaline earth and transition halide salts; and injecting at least one oxidizing gas comprising air and steam into the reaction chamber; injecting steam into the reaction chamber, wherein the carbonaceous feedstock, the air and the steam are injected into the reaction chamber under conditions and for a residence time sufficient to form an activated carbon having a salt consisting of halide salt having a cation and an anion dispersed on the surface of the activated carbon.
