|20140018587||NOVEL FUEL COMPOSITION - This invention relates to fuel compositions for use in combustion engines, such as for motor vehicle and aircraft usage. The fuel composition contains at least 99.5% of aromatic hydrocarbons and paraffinic hydrocarbons. The composition also preferably contains no lead, no multi-ring compound (only single ring compounds are present), less than about 15 ppm sulfur, and/or less than about 5 ppm nitrogen species. The resulting fuel is a drop-in fuel that provides clean burning with little to no engine deposit, high lubricity, high stability, and low corrosion.||01-16-2014|
|20130270483||CATALYTICAL GASIFIER CONFIGURATION FOR BIOMASS PYROLYSIS - The invention relates to systems and methods for producing synthesis gas. In particular, the systems of the present invention include two catalytic reactors in series, a wet reformer/gasifier followed by a dry reformer. The systems produce synthesis gas with very little to no methane.||10-17-2013|
|20120280496||JOINT WITH HEAT-SHIELDING ELEMENT - A joint for connecting pipe sections is provided in which a portion of the joint includes a first pipe section, a first reducer fitting section, a first flange attached to the first pipe section and having holes for receiving fasteners, and a fluid conduit (such as a pipe sleeve) positioned inside at least a portion of the first pipe section and the first reducer fitting, wherein the fluid conduit forms an annular space defined by the outside surface of the fluid conduit wall and the inner walls of the first pipe section and the first reducer fitting. The annular space separates the heat-sensitive flange, a flange gasket, and the flange fasteners from high-temperature fluids flowing in the fluid conduit, thereby allowing for the use of lower rated and less expensive components than would otherwise be required in a direct heat contacting arrangement.||11-08-2012|
|20120280495||CERAMIC-TO-METAL FLANGE CONNECTION - This invention describes a flanged connection or attachment joint between two coaxial, cylindrically-shaped members having different thermal coefficients of expansion, the connection/attachment being suitable for use in high temperature fluid transport.||11-08-2012|
|20120116137||SINGLE LOOP MULTISTAGE FUEL PRODUCTION - Synthetic fuels are produced from synthesis gas in a four-stage reactor system with a single recycle loop providing the requisite thermal capacity to moderate the high heat release of the reactions and to provide the reactants and reaction environments for the efficient operation of the process. The first stage converts a portion of the synthesis gas to methanol, the second stage converts the methanol to dimethylether, the third stage converts the methanol and dimethylether to fuel and the fourth stage converts the high melting point component, durene, and other low volatility aromatic components such as tri- andtetra-methylbenzenes to high octane branched paraffins. The four-stage catalyst used for hydrotreating is resistant to CO poisoning. The reactions i produce water as a side product that is carried through to a high pressure separator after the fourth stage. The streams from the separator are a liquid fuel stream, a water stream and a gaseous stream that contains light hydrocarbon gases and the unreacted synthesis gas. The larger part of this gas stream is recycled to the inlet of the first stage and mixed with the fresh synthesis gas stream. Alternatively, the fresh synthetic gas stream is mixed with the product of the second stage. The smaller part of the gas stream from the separator is sent to hydrocarbon recovery and to fuel gas used for providing preheat of various streams. The liquid fuel is sent for blending into fuel products, such as gasoline, jet fuel, or diesel, and the water stream can be sent, for example, to the synthesis gas producing plant for steam generation.||05-10-2012|
