The present invention describes the process of preparing ceramic materials for absorption of acidic gases, mainly carbon dioxide, in exhaust systems and/or present indoors. Ceramic materials are formed by a mixture of alkali carbonate with alkaline earth metal oxide/hydroxide associated with a binding component, but non-limiting. The alkali carbonate comprises sodium, potassium carbonate, or a mixture of both. The alkaline earth metal oxide/hydroxide may be formed from magnesium oxide or magnesium hydroxide as well as calcium oxide and/or calcium hydroxide.

The invention includes a metal trapping additive that comprises calcium, boron and magnesia-alumina. The invention also includes a process for the catalytic cracking of feedstock comprising contacting the feedstock under catalytic cracking conditions with a FCC catalyst and the metal trapping additive.

A clumpable animal litter comprises composite particles of filler materials, such as limestone and sand, and sodium bentonite. The filler materials have a lower bulk density as compared to a granular mixture of the same percentage of filler and sodium bentonite clay and contain up to eighty-five percent less clay.

An X-ray amorphous magnesium carbonate is disclosed that is characterized by a cumulative pore volume of pores with a diameter smaller than 10 nm of at least 0.018 cm.sup.3/g, and a specific surface areas of at least 60 m.sup.2/g. The X-ray amorphous magnesium carbonate is produced by reacting an inorganic magnesium compound with alcohol in a CO.sub.2 atmosphere. The X-ray amorphous magnesium carbonate can be a powder or a pellet and acts as a desiccant in, for example, production of food, chemicals or pharmaceuticals.

Systems and methods for generation of lime hydrate compounds and particularly highly reactive hydrated lime (HRH) with a reduced resistivity through the inclusion of a sodium compound generally in the slaking water used in generating the lime hydrate or HRH. The compound may then be used in systems which include a Electrostatic Precipitator (ESP) for SO.sub.2 mitigation without many of the associated problems in ESP performance.

A system for and method of, processing post-consumer and post-industrial waste streams, producing active ingredients for waste stream processing, processing aqueous waste streams, preparing and collecting a multi-purpose chemical precursor, removing phosphates, nitrates, heavy metals, and other contaminants from aqueous waste streams, collecting and processing a post-consumer and post-industrial product from aqueous waste streams, administering and positioning assets and processes associated with waste stream processing, and scheduling operations for sub-systems of the system.

Various embodiments disclosed relate to sorbents for the oxidation and removal of mercury. The present invention includes removing mercury from a mercury-containing gas using a halide-promoted and optionally ammonium-protected sorbent that can include carbon sorbent, non-carbon sorbent, or a combination thereof.

Sorbent compositions containing calcium and iodine are added to coal to mitigate the release of mercury and/or other harmful elements into the environment during combustion of coal containing natural levels of mercury.

Described herein are methods of forming a VOC and odor-reducing building panel. The methods include providing a substrate; applying a wet-state coating to a major surface of the substrate, the wet-state coating comprising carrier comprising water; and drying the wet-state coating, thereby evaporating at least 95 wt. % of the carrier to form a dry-state coating.
