    摘要： A method is disclosed for maintaining a volumetric gas to liquid ratio in a segmented gas/liquid flow along a reactor of monolithic catalyst beds in series. The present invention includes the steps of: initiating the segmented gas/liquid flow at a first end of the reactor by introducing feed liquid and feed gas both at a predetermined volume and a predetermined flow rate; injecting an additional amount of gas at least once into any of the spaces between catalyst beds; and combining the segments of the segmented gas/liquid flow at a second end of the reactor. The injection of gas is controlled such that the segmented gas/liquid flow can be maintained near or at the Taylor regime.

    摘要： A process for hydrogenating polyenes, especially 1,5,9-cyclododecatriene, to the corresponding monoenes, especially cyclododecene, using homogeneous ruthenium catalysts comprises hydrogenating in the presence of a carboxylic acid, advantageously a C1-C20 monocarboxylic acid, a C2-C6 dicarboxylic acid, cyclohexylcarboxylic acid, benzoic acid, terephthalic acid, phthalic acid or phenylacetic acid, especially acetic acid, propionic acid, succinic acid or adipic acid or a C12-C20 fatty acid. The homogeneous ruthenium catalyst is advantageously generated in situ prior to the hydrogenation. The in situ generation is carried out in the additional presence of CO or formaldehyde and the hydrogenation in the additional presence of triphenylphosphine.

    摘要： A process for preparing a supported catalyst comprising a transition metal selected from palladium, platinum, nickel, cobalt or copper on an aerogel support, which includes the steps of providing a mixture containing an alkoxide precursor of the aerogel, a chelate complex of the transition metal with a chelating agent having Si(OR)3 anchor groups, and an organic solvent in which the chelate complex is soluble; hydrolyzing the mixture by admixing it with water to form a gel; and converting the gel under supercritical conditions into the transition metal aerogel-supported catalyst. The supported catalyst has an especially homogeneous distribution of the metal component and is suitable, for example, for use as a hydrogenation catalyst.

    摘要： The present invention deals with the catalytic hydrogenation of fluid used to cool and dielectrically insulate an x-ray generating device within an x-ray system. According to the present invention, a method and apparatus are provided for hydrogenating fluid that has been exposed to x-rays to reduce the amount of H2 gas, free hydrogen atoms and unsaturated molecules in the fluid. The method comprises exposing the fluid within the x-ray system to a catalytically effective amount of catalyst. The catalyst operates in temperatures in the range of about 10-300° C. and pressures in the range of about 0.1-30 atmospheres. The catalyst may comprise a solid, non-soluble catalyst, a soluble catalyst, or a combination of both. A suitable solid, non-soluble catalyst comprises Group VIII elements and their compounds. Group VIII elements comprise iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium and platinum. The catalytically effective amount of solid catalyst ranges from about 1-100 cm2 of surface area of solid catalyst per liter of fluid. Additionally, a suitable soluble catalyst may be added to the fluid and may comprise tris(triphenylphosphine) rhodium (I) chloride, precious metals in solution such as HRu(C2H4)(C6H4PPh2)(PPh3)2), Wilkinson's catalyst which comprises a rhodium, chromium, phosphorus triphenyl chloride compound, and other similar compounds. A catalytically effective amount of soluble catalyst may comprise from about 0.01-1 gram per liter of fluid. The fluid may comprise about 99.7% hydrocarbon, about 0.1% soluble catalyst, and the remainder comprising conditioning additives. The hydrocarbon preferably comprises about 99.7% hydrogenated light naphthenic petroleum distillates.
