Abstract: A process for reducing the amount of mercaptan sulfur in a petroleum stream without significantly changing its octane value. The process comprising a three-phase system wherein the petroleum stream to be treated is passed through a fixed bed of catalyst in the presence of a stripping gas. The stripping gas can be either hydrogen containing gas or an method wherein the composition of the catalyst utilized varies according to the stripping gas.

Abstract: Diesel fuels or blending stocks having excellent lubricity, oxidative stability and high cetane number are produced from non-shifting Fischer-Tropsch processes by separating the Fischer-Tropsch product into a lighter and heavier fractions, e.g., at about 700° F., subjecting the 700° F.+ fraction to hydro-treating, and combining the 700° F.− portion of the hydrotreated product with the lighter fraction that has not been hydrotreated.

Abstract: Discloses environmentally friendly, low temperature base oils and drilling fluids. The drilling fluid is constituted of one or more of weighting agents, emulsifiers, wetting agents, viscosifiers, fluid loss control agents, proppants, and other particulates such as used in a gravel pack, emulsified with a paraffinic solvent composition which forms a continuous oil phase, or water-in-oil invert phase. The solvent composition is constituted of a mixture of C10-C24 n-paraffins and isoparaffins having an isoparaffin:n-paraffin molar ratio ranging from about 0.5:1 to about 9:1, the isoparaffins of the mixture contain greater than 30 percent, preferably from about 30 percent to about 50 percent, of mono-methyl species, and greater than 30 percent, preferably from about 30 percent to about 50 percent of multi-methyl branched species and isoparaffins which contain one or more branches of carbon number higher than methyl, based on the total weight of the isoparaffins in the mixture.

Abstract: The invention describes a method for preparing a low sulfur motor gasoline utilizing ethanol and caustic extraction.

Abstract: Discloses environmentally friendly, low temperature base oils and drilling fluids, or drilling mud compositions useful in the production of oil and gas. The drilling fluid is constituted of one or more of weighting agents, emulsifiers, wetting agents, viscosifiers, fluid loss control agents, proppants, and other particulates such as used in a gravel pack, emulsified with a paraffinic solvent composition which forms a continuous oil phase, or water-in-oil invert phase. The solvent composition is constituted of a mixture of C.sub.10- C.sub.24 n-paraffins and isoparaffins having an isoparaffin:n-paraffin molar ratio ranging from about 0.

Abstract: The instant invention is directed to an integrated process for producing a hydroisomerate in the presence of sulfur comprising the steps of (a) separating a natural gas into a first stream comprising a C.sub.5 + gas field condensate containing sulfur and a second stream comprising said natural gas having said a C.sub.

Abstract: The present invention is a method for controlling a process for producing a distillate fuel heavier than gasoline. The process includes several different fractions, streams, including alcohols, olefins, and acids. At least one of the streams is irradiated with IR radiation, allowing the determination of the concentrations of at least one of alcohols, olefins and acids. The temperature of the separator is then adjusted to change the concentrations to pre-determined values.

Abstract: Clean distillate useful as a diesel fuel or diesel blending stock is produced from Fischer-Tropsch wax by separating wax into heavier and lighter fractions; further separating the lighter fraction and hydroisomerizing the heavier fraction and that portion of the light fraction below about 500.degree. F. The isomerized product is blended with the untreated portion of the lighter fraction.
