Abstract: Sorbents for removal of mercury and other pollutants from gas streams, such as a flue gas stream from coal-fired utility plants, and methods for their manufacture and use are disclosed. Embodiments include brominated sorbent substrate particles having a carbon content of less than about 10%. Other embodiments include one or more oxidatively active halides of a nonoxidative metal dispersed on sorbent substrate particles mixed with activated carbon in an amount up to 30% by weight. Further embodiments include physical blending of a flow modifier into the sorbent composition.

Abstract: Sorbents for removal of mercury and other pollutants from gas streams, such as a flue gas stream from coal-fired utility plants, and methods for their manufacture and use are disclosed. The methods include injecting a sorbent consisting essentially of recovered and separated fluid cracking catalyst particles into a flue gas stream.

Abstract: The present invention provides a thermal paper composite precursor comprising (a) a substrate layer; and (b) a base layer positioned on the substrate layer, the base layer comprising a binder and at least one porosity improver wherein the thermal paper composite precursor has a thermal effusivity that is at least about 2% less than the thermal effusivity of porosity improver-less thermal paper composite precursor. The thermal paper composite precursor is useful in making thermal paper composite.

Abstract: An alumina-based perovskite is formed by mixing a lanthanide source with a transitional alumina to form a dual-phase composition comprising in situ formed LnAlO3 dispersed in alumina. A second metal can be also included to form LaMO3 perovskite on alumina. The lanthanide content of the composition may range from about 6 to 35 wt. %, and the second metal from about 0.5 to 20 wt. %, to yield a high surface area composition which is useful as a catalyst or catalyst support such as for precious metals.

Abstract: Methods of manufacturing bentonite sorbents for removal of pollutants including mercury from gas streams, such as a flue gas stream from coal-fired utility plants are disclosed. The methods include mixing bentonite sorbent particles with a sulfide salt and a metal salt to form a metal sulfide on the outer surface of the bentonite sorbent particles.

Abstract: Provided herein is a non-single phase perovskite-type bulk material comprising one or more of Ru and Ir. In one embodiment, the surface region of the material is enriched with one or more of Ru and Ir relative to the bulk material. Also provided are methods for preparing the non-single phase, surface enriched perovskite-type material, catalytic articles comprising the non-single phase, surface enriched perovskite-type material and methods for their preparation, and methods for treating exhaust emissions using the non-single phase, surface enriched perovskite-type material.
