Abstract: A process for converting biomass to products is described. Biomasss is contacted with hydrogen in the presence of a fluidized bed of hydropyrolysis catalyst in a reactor vessel under hydropyrolysis conditions; and products and char are removed from the reactor vessel. The products leave the fluidized bed at an exit bed velocity, the char has a settling velocity that is less than the exit bed velocity and hydropyrolysis catalyst has a settling velocity that is greater than the exit bed velocity.

Abstract: A system for fluid transport at elevated temperatures having a conduit having a fluid inlet end and a fluid outlet end and at least one heating element disposed within the conduit providing direct heating of a fluid flowing through the conduit. The system is particularly suited for preventing condensable constituents of a high temperature fluid from condensing out of the fluid prior to analysis of the fluid. In addition, operation of the system so as to prevent the condensable constituents from condensing out of the fluid surprisingly does not alter the composition of the fluid.

Abstract: A dilution apparatus for diluting a gas sample. The apparatus includes a sample gas conduit having a sample gas inlet end and a diluted sample gas outlet end, and a sample gas flow restricting orifice disposed proximate the sample gas inlet end connected with the sample gas conduit and providing fluid communication between the exterior and the interior of the sample gas conduit. A diluted sample gas conduit is provided within the sample gas conduit having a mixing end with a mixing space inlet opening disposed proximate the sample gas inlet end, thereby forming an annular space between the sample gas conduit and the diluted sample gas conduit. The mixing end of the diluted sample gas conduit is disposed at a distance from the sample gas flow restricting orifice. A dilution gas source connected with the sample gas inlet end of the sample gas conduit is provided for introducing a dilution gas into the annular space, and a filter is provided for filtering the sample gas.

Abstract: A method for producing a catalytically-active material having at least one base component and at least one catalytically-active component in which the at least one base component is heated to a softening or melting temperature to form a softened or molten base component. While the base component is in the softened or molten state, at least one catalytically-active component is incorporated into or onto the base component, forming the catalytically-active material. In accordance with one embodiment, a catalyst precursor is introduced into the base component and subsequently transformed to a catalytically-active component.

Abstract: An apparatus and method for diluting and cooling that is extracted from high temperature and/or high pressure industrial processes. Through a feedback process, a specialized, CFD-modeled dilution cooler is employed along with real-time estimations of the point at which condensation will occur within the dilution cooler to define a level of dilution and diluted gas temperature that results in a gas that can be conveyed to standard gas analyzers that contains no condensed hydrocarbon compounds or condensed moisture.

Abstract: A catalytically active glass-ceramic and method for producing a catalytically active multi-phase glass-ceramic in which at least one catalyst precursor is mixed with a glass-ceramic precursor formulation to form a catalyst precursor/glass-ceramic precursor mixture. The catalyst precursor/glass-ceramic precursor mixture is then melted to form an amorphous glass material which, in turn, is devitrified to form a polycrystalline ceramic. The polycrystalline ceramic is then activated, forming a catalytically active multi-phase glass-ceramic.

Abstract: The present invention relates to a pneumatic tire having a rubber component comprised of (A) 100 parts by weight of at least one elastomer containing olefinic unsaturation; (B) 10 to 120 phr of a filler selected from carbon black and silica; (C) 0.1 to 10 phr of N,N?-(m-phenylene) bismaleamic acid; (D) 0.1 to 0.5 phr of zinc dibenzyl dithiocarbamate; and (E) 0.1 to 5 phr of an additional cure accelerator.

Abstract: Evaporative cooling apparatus monitors light and heavy temperature averages to minimize cycling of the apparatus on-and-off when the apparatus is being turned on in the morning when the ambient temperature is rising and is being turned off in the afternoon when the ambient temperature is falling. The apparatus is suspended above the ground and includes a hollow housing with a top portion and a bottom portion, a fan mounted in the top portion of the housing to direct air flow through the housing downwardly toward the ground, and nozzles mounted inside the housing to direct water droplets into air flowing from the fan through the housing. The apparatus also includes a hollow, tapered member which captures a portion of the air flow from the fan and directs the airflow into a central area of the housing to insure that air flowing through the central area moves downwardly toward the ground.
