Abstract:
A PROCESS FOR SIMULTANEOUSLY DESALTING A HYDOCARBON FEEDSTOCK AND REMOVING IRON PRESENT IN THE HYDOCARBON FEEDSTOCK AS A SOLUBLE ORGANOMETALLIC COMPOUND WHICH COMPRISES CONTACTING THE FEEDSTOCK WITH AN AQUEOUS SOLUTION CONTAINING CYANIDE ION AND THEN SEPARATING AN AQUEOUS BRINE PHASE FROM THE HYDROCARBON FEEDSTOCK. PREFERABLY, THE AQUEOUS SOLUTION CONTAINS IN ADDITION TO CYANIDE ION A REDUCING AGENT SUCH AS AMMONIUM SULFIDE AND PREFERABLY THE FEED IS A CRUDE OIL OR A RESIDUUM FRACTION.
Abstract:
This invention is concerned with catalysts, particularly those useful for hydroconversion, preferably hydrocracking, a process for using the catalyst, and a method for manufacturing the catalyst, which comprises: A. forming in an aqueous medium a gelatinous precipitate and a finely divided catalytically active metal, the gelatinous precipitate comprising an inorganic oxide or precursor thereof and the metal being formed by reduction in the aqueous medium of a metal compound dissolved therein; B. intimately intermixing the gelatinous precipitate and the metal within 2 hours of formation of the gelatinous precipitate, thereby forming a catalyst precursor; C. converting the catalyst precursor to a catalyst. The conversion includes at least a step of heating the catalyst precursor at 500*-1,800* F. for 1 to 48 hours. The preferred catalyst comprises a noble metal, preferably palladium on a silica-alumina support, particularly useful for hydrocracking processes.
Abstract:
A waxy hydrocarbon oil feed is catalytically dewaxed in the presence of hydrogen at dewaxing conditions using a catalyst comprising molybdenum and combined fluorine, calculated as fluorine, in association with a porous solid carrier.
Abstract:
A PROCESS FOR THE REMOVAL OF IRON FROM IRON-CONTAMINATED HYDROCARBON OIL BY CONTACTING THE OIL WITH A TREATING AGENT COMPRISING AN AQUEOUS SOLUTION OF CYANIDE ION. IRON MAY BE SELECTIVELY REMOVED FROM AN OIL CONTAMINATED WITH NICKEL AND VANADIUM AS WELL AS IRON. A REFINERY FOUL WATER MAY BE THE SOURCE OF THE CYANIDE ION.
