    摘要: An alpha-olefin is oligomerized in the presence of a three-component catalyst comprising a particulate solid adsorbent having boron trifluoride and water adsorbed on the solid adsorbent. For example, 1-decene is oligomerized to a product predominating in the trimer and tetramer using silica as the solid adsorbent.

    摘要: An integrated in situ combustion process for recovering subterranean liquid and solid carbonaceous deposits in which the resulting flue gas of low heating value is combusted at substoichiometric conditions over two different oxidation catalysts in two combustion zones in series and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit. One of the oxidation catalysts comprising platinum and at least one metal cocatalyst selected from Groups IIA and VIIB, Group VIII up through atomic No. 45, the lanthanides, chromium, zinc, silver, tin and antimony is provided to reduce the carbon monoxide in the combusted flue gas.

    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.
