  • Patent number: 8685351
    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.

  • Patent number: 7902117
    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.

  • Publication number: 20100227758
    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.
