    A catalytic reactor with an auxiliary heating structure for raising the temperature of a fluid passing therethrough whereby the catalytic reaction is promoted. The invention is a apparatus employing multiple electrical heating elements electrically isolated from one another by insulators that are an integral part of the flow path. The invention provides step heating of a fluid as the fluid passes through the reactor

    Catalytic Combustion of Gasified Coal for Low-Emissions Gas Turbines

    In response to the Department of Energy’s (DOE) goals of developing low emission, coal-based power systems, Precision Combustion, Inc. is developing a low, single digit ppm NOx emissions system for high firing temperature IGCC systems. The present paper presents emissions data for syngas and alternate fuels tested successfully. Subscale testing results at 10 atmospheres include NOx emissions meeting DOE\u27s target of 0.01 lbs/MMBtu (3 ppm at 15% O2) and were below this value under some operating conditions during parametric testing

    Anticancer drug development is inefficient, but genetically engineered murine models (GEMM) and orthotopic, syngeneic transplants (OST) of cancer may offer advantages to in vitro and xenograft systems

    Catalytic Isobutane Alkylation - U.S. Patent 9,433,913

    No full text
    A novel catalytic reactor is provided for controlling the contact of a limiting reactant with a catalyst surface. A first flow vessel defines an interior surface and an exterior surface, and the interior surface has a catalyst deposited on at least a portion thereof. A second flow vessel is positioned within the first flow vessel and the second flow vessel defines a porous surface designed to deliver a fluid uniformly to at least a portion of the interior surface of the first flow vessel

    Dry, low NOx pilot - U.S. Patent 6,270,337

    No full text
    This invention relates to an apparatus and method for increasing the reactivity of a fuel/air mixture prior to homogenous combustion of the mixture. More specifically, this invention is a pilot for a gas turbine combustor which utilizes the heat of combustion within the pilot to increase the reactivity of a portion of the fuel/air mixture utilized by the pilot

    Catalytic reactor for low-Btu fuels - U.S. Patent 7,521,028

    No full text
    An improved catalytic reactor includes a housing having a plate positioned therein defining a first zone and a second zone, and a plurality of conduits fabricated from a heat conducting material and adapted for conducting a fluid therethrough. The conduits are positioned within the housing such that the conduit exterior surfaces and the housing interior surface within the second zone define a first flow path while the conduit interior surfaces define a second flow path through the second zone and not in fluid communication with the first flow path. The conduit exits define a second flow path exit, the conduit exits and the first flow path exit being proximately located and interspersed. The conduits define at least one expanded section that contacts adjacent conduits thereby spacing the conduits within the second zone and forming first flow path exit flow orifices having an aggregate exit area greater than a defined percent of the housing exit plane area. Lastly, at least a portion of the first flow path defines a catalytically active surface

    Main burner, method and apparatus - U.S. Patent 6,748,745

    No full text
    The invention is a method and apparatus for use therewith for a main burner of a gas turbine. The method employs catalytic combustion to support main combustion. More specifically, a rich fuel/air mixture is catalytically oxidized with the resulting reacted mixture being made lean by having additional air added thereto. The resulting lean mixture is then combusted in the presence of the main mixture that is also lean thereby supporting combustion of the main mixture. The method allows for enhanced turndown of a lean main mixture
