    Abstract: A reagent is provided for removing mercury (Hg). The reagent contains metal carbonates compound with layers structure. The contents of metals of reagent can be adjusted using this method. The reagent can be manufactured with kilogram grade per batch. The common ions, like Mg, Ca, Mn, Fe, Co, Ni, Cu, Zn, etc., can be contained in the reagent. The manufacture method provides a low-cost way for the Hg sorbent and the content ratio of metal oxides can be higher than 50 wt %. The manufacture is operated at a temperature more than 200° C. and can be integrated with existing technology such as denitration catalysts in industry for removing Hg. In another word, the present invention fabricates a mercury-removing reagent of metal-M/aluminum carbonates (M-Al—CO3), which can be potentially combined with commercially selective catalytic reduction (SCR) catalysts for developing medium-high-temperature mercury-removing reagent with mercury-removing efficiency further enhanced.

    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.

    Abstract: An aggregate composition and process for making the aggregate composition. The aggregate composition includes an insoluble rare earth-containing compound and a polymer binder. The insoluble rare earth-containing compound can include one or more of cerium, lanthanum, or praseodymium. A suitable insoluble cerium-containing compound can be derived from cerium carbonate or a cerium salt. In a specific embodiment, the aggregate composition consists essentially of one or more cerium oxides, the polymer binder and optionally a flow aid. A process for making the composition includes mixing the insoluble rare earth-containing compound with a polymer binder to form a mixture, and subjecting the mixture to mechanical, chemical and/or thermal treatment to adhere the rare earth compound to the polymer binder. The aggregate composition can be used in a variety of fluid treatment applications to remove one or more chemical and biological contaminants in a fluid.
