Patent number: 4293498Abstract: The present invention provides a process for the preparation of oxidation catalysts containing mixed oxides of vanadium and phosphorus, which catalysts are particularly effective in the oxidation of n-butane, n-butenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapor phase to produce high yields of maleic anhydride with good selectivity. A vanadium compound is introduced into an olefinic halogenated organic liquid medium, a phosphorus-containing compound is added to the medium, reduction of at least a portion of the vanadium to a +4 valence state is effected either prior to or subsequent to the addition of the phosphorus-containing compound, and the resulting vanadium-phosphorus oxide catalyst precursor is recovered, dried and calcined.Type: GrantFiled: October 22, 1980Date of Patent: October 6, 1981Assignee: Standard Oil Co.Inventors: Michael F.

Patent number: 4287752Abstract: Disclosed is a method and an apparatus for analyzing the composition of a gasoline-range petroleum product using a new copper on silica gel adsorption composition. The copper on silica gel adsorption composition is capable of separating olefins from saturates in a mixture by temporarily retaining the olefins while allowing the saturates to pass through. The method of analysis entails passing a gasoline sample through an absorption column whereby the aromatics are retarded while the saturates and olefins pass through. The saturates and olefins are then directed through the copper on silica gel composition wherein the olefins are retained while the saturates pass through into a detector and are measured. Once all the saturates are removed from the system, the aromatics are backflushed from the absorption column and are routed into the detector for measurement.Type: GrantFiled: August 3, 1979Date of Patent: September 8, 1981Assignee: Standard Oil Co. (Indiana)Inventor: George B. Ury
