  • Patent number: 8609580
    Abstract: The present invention provides catalytic adsorbents formed from doping activated carbon with a dispersed halide salt. The catalytic adsorbents provided herein are stable and harmless at room temperature, yet allow for chemical adsorption at elevated temperatures typical of those for flue gas streams. The present invention also provides methods of manufacturing the doped activated carbon adsorbents.

  • Patent number: 8329614
    Abstract: Solid adsorbents, following their use for mercury removal from flue gas, that do not interfere with the ability of air-entraining additives (such as surfactants) to form stable bubbles when added to fly ash containing the adsorbents. The interference is overcome by heating the materials used in the manufacture of the adsorbent so that magnesium hydroxide and/or one or more alkali compounds containing one or more silicate, aluminate, and/or phosphate moiety, added or already present in the materials, binds multivalent cations present in the materials that could otherwise interfere with the surfactant activity.

  • Publication number: 20120277097
    Abstract: A gas mixture preheated to high temperatures using an oxy-fuel, an oxygen-enriched air-fuel or an air-fuel burner is used to devolatilize and partially oxidize carbonaceous feedstock, thereby producing an active residual char that can be used in applications utilizing activated carbon. Use of hot gas and ground carbonaceous feedstock allows the equipment to be minimized, thereby allowing the activated carbon to be produced at or near points of use, for example the production of activated char at or near utility boilers for use in the reduction of mercury emissions from flue gas streams.

  • Patent number: 8287876
    Abstract: Recombinant chimeric antigens comprising unmodified and modified reactive polypeptide fragments of expressed product of the recombinant 56 kDa proteins of multiple strain of scrub typhus, such as Karp, Kato (Ktr56), Gilliam (Gmr56), and TA763 (TAr56). The invention is useful for detecting prior exposure to a number of strains of scrub typhus, based on the strength of reaction toward the chimeric protein and as a component in vaccine formulations and production of immune globulins for passive prophylaxis and immunity in subjects against heterologous infections.
