    摘要: A system is proposed for the purification of exhaust gases from internal combustion engines, preferably the reduction of nitrogen oxides in exhaust gases from internal combustion engines in which nitrogen is selectively formed as substantially the only nitrogen-containing product. The exhaust gas is contacted at an elevated temperature with a noble metal in a reducing atmosphere, wherein nitrogen oxides are selectively converted to nitrogen as substantially the only nitrogen containing product, and/or is contacted with a noble metal in an oxidizing atmosphere, wherein carbon monoxide and unburned hydrocarbons are converted to carbon dioxide and water, said noble metal being distended on a microporous glass body. In a preferred embodiment the exhaust gas is contacted at an elevated temperature in a reducing atmosphere with ruthenium supported on a microporous glass body comprising a leached, phase-separated alkali borosilicate.

    摘要: A process for converting coal to liquid hydrocarbonaceous products involving a liquefaction reaction in the presence of a coal derived recycle slurry and a non-coal derived solvent comprising a hydrocarbonaceous oil or distillation bottom residue thereof intrinsically contaminated with greater than 300 ppm total of vanadium and nickel. The liquefaction reaction is performed under hydrogen pressure (approximately 500-4000 psi) and under elevated temperature (approximately 300.degree.-500.degree. C.) using a weight ratio of non-coal derived solvent to coal of about 1/1 or less. The conversion of coal to liquids is greatly enhanced by the use of such a non-coal derived solvent under these conditions.

    摘要: Ethylene is oligomerized by contacting ethylene with a catalyst produced by contacting (a) a refractory metal oxide/silica support such as alumina/silica wherein the silica content of the support is from about 2 to about 95 weight percent and the metal oxide content of the support is from about 5 to about 98 percent with (b) a tris(cyclopentadienyl)trinickel dicarbony. This process is characterized by a relatively high reaction rate at moderate temperatures and pressures and results in the production of relatively high proportions of desirable trimer, tetramer, pentamer, and higher olefinic products.
