    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.

    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 the conversion of gas oil to a naphtha pyrolysis feedstock and needle coke comprising thermally cracking the gas oil to produce a product comprising cracked naphtha and aromatic tar oil, delay coking said aromatic tar oil to produce needle coke and coker naphtha, and hydrotreating said cracked naphtha and said coker naphtha at a temperature at least 50.degree. F. (28.degree. C.) lower than the temperature in the thermal cracking and coking zones to avoid hydrocarcking reactions and to produce a hydrogenated naphtha containing at least 10 volume percent of cycloparaffins. Said hydrogenated naphtha is thereupon passed through a pyrolysis zone without added molecular hydrogen and without a catalyst operated at a temperature between 1,300 and 2,300.degree. F. (704 and 1,260.degree. C.) and a residence between 0.05 and 2 seconds to produce a product containing ethylene. The ethylene yield can be increased by adding a sulfur compound to the hydrogenated naphtha stream flowing to the pyrolysis zone.

    摘要： When ethylene is telomerized to produce alpha-olefins in the presence of an organo-aluminum catalyst, the aluminum catalyst is present in the normally liquid alpha-olefin product and must be removed prior to distillation of that product. This removal is accomplished in two zones. Water is added to the alpha-olefin product containing the organo-aluminum catalyst in a first zone to produce an aqueous phase containing a suspension of aluminum hydroxide and an organic phase containing the alpha-olefins. After removal of the organic phase, a sufficient amount of an aqueous solution of a polyacrylamide in anionic form is added to the aqueous phase to result in at least 90 percent of the aluminum hydroxide settling in a time period of less than ten minutes at ambient conditions.
