    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： 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 catalyst for the conversion of synthesis gas comprising cobalt on a high surface area, high purity, low acidity alumina support of gamma-alumina, eta-alumina or mixtures thereof, whereby the catalyst is prepared by (A) impregnation of the alumina support with a non-aqueous, organic solvent impregnation solution of cobalt nitrate containing sufficient amounts of a Group IIIB or IVB metal salt to provide said catalyst with from about 0.05 to about 100 parts by weight of a Group IIIB or IVB metal oxide per 100 parts by weight cobalt, (B) reduction of the impregnated alumina support by heating, in the presence of hydrogen, at a heating rate of from about 0.5.degree. to about 5.degree. C. per minute to a maximum temperature in the range of 180.degree. to about 220.degree. C. for a hold time of 6 to about 24 hours and thereafter heating the impregnated alumina support in the presence of hydrogen while heating up to a maximum hold temperature of from about 250.degree. to about 400.degree. C. for a hold time of 6 to about 65 hours.

    摘要： A catalytically hydrogenated naphtha stream containing less than 10 ppm by weight of sulfur is pyrolyzed without added hydrogen to a product including ethylene. Selectivity to ethylene is increased by adding a sulfur compound to increase the sulfur content to above 20 ppm by weight based on hydrogenated naphtha. Addition of the sulfur compound increases the quality of hydrogenated naphtha as a pyrolysis feedstock nearly to that of a C.sub.2 to C.sub.5 paraffin stream.
