    Abstract: A process of treating a gas stream containing mercury and acid gas pollutants is disclosed. The process includes applying a sorbent composition into a gas stream in order to adsorb mercury containing compounds and acid gas pollutants. The sorbent composition includes a compound having the formula (SiO2)x(OH)yMzSaF.B. The combination of basic inorganic solids for the adsorption of acid gases, and metal sulfide-doped silica for the adsorption of mercury provides dual sorbent functionality, along with additional benefits for each individual sorbent: silica for moisture retention on the surface of the basic inorganic particle and adsorption of acid gas, which will improve metal sulfide performance at higher operating temperatures. The use of a hygroscopic solid effectively dries the metal sulfide-doped silica slurry without the use of filtration of drying equipment, providing significant economic benefit for the manufacture of metal sulfide-doped silica material.
