  • Patent number: 9849446
    Abstract: Systems and methods are provided for slurry hydroconversion of a heavy oil feedstock, such as an atmospheric or vacuum resid, in the presence of an enhanced or promoted slurry hydroconversion catalyst system. The slurry hydroconversion catalyst system can be formed from a) a Group VIII non-noble metal catalyst precursor/concentrate (such as an iron-based catalyst precursor/concentrate) and b) a Group VI metal catalyst precursor/concentrate (such as a molybdenum-based catalyst precursor/concentrate) and/or a Group VI metal sulfided catalyst.

  • Patent number: 9816039
    Abstract: A heavy petroleum oil feed is upgraded by having its amenability to cracking improved by subjecting the oil to selective partial oxidation with a catalytic oxidation system to partially oxidize aromatic ring systems in the heavy oil. The partially oxidized oil can then be cracked in the conventional manner but at lower severities to lower molecular weight cracking products. The cracking following the partial oxidation step may be thermal in nature as by thermal cracking, delayed, contact or fluid coking or fluid catalytic cracking or hydrogenative as in hydrocracking.

  • Patent number: 9505987
    Abstract: Heavy oils containing metalloporphyrins principally of nickel and vanadium are demetallized using an oxidizing agent such as aqueous hydrogen peroxide and catalytic amounts of phosphoric acid, preferably with tungstic acid in combination with a phase transfer agent. Up to 99% of the Ni and V are deposited in the aqueous phase and are removed from the oil. The homogenous, water soluble reactants and catalyst have the advantage of being separated more easily from the Ni and V dissolved in the aqueous phase than the same metals deposited on solid phase heterogeneous catalysts.

  • Publication number: 20120330057
    Abstract: A method for recovering high molecular weight naphthenic tetra-acids, particularly ARN acids from a calcium naphthenate deposit. Calcium naphthenate deposits contain large amounts of calcium naphthenate salts of ARN acids. The method dual solvent extraction process in which the naphthenic tetra-acids chemically bound as calcium naphthenate salts are converted into free acid monomers by an aqueous acid. The resulting free acid monomers are then dissolved into an organic solvent phase and the counterions dissolve in the aqueous acid phase. The naphthenic tetra-acids are then recovered from the organic solvent phase.

  • Patent number: 6232276
    Abstract: A lubricating oil composition is provided comprising a major amount of an oil of lubricating viscosity and a minor amount of at least one trinuclear molybdenum compound. Preferably, the trinuclear molybdenum compound is selected from those compounds having the formula Mo3SkL4Qz and mixtures thereof in which L is a ligand having organo groups with a sufficient number of carbon atoms to render the compound soluble in the oil, k varies from 4 through 7, Q is selected from the group of compounds having lone pair electrons including water, amines, alcohols, phosphines, and ethers, and z ranges from 0 to 5. In general, the organo groups of the mono-anionic ligands will be the same although they may be different, and they preferably are selected from alkyl, aryl, substituted aryl, and ether groups. For example, when L is a dialkyldithiocarbamate or a dialkyldithiophosphate, the alkyl groups will have from about 1 to 30 carbon atoms.

  • Patent number: 5750478
    Abstract: This invention relates to synthetic based turbo oils, preferably polyol ester-based turbo oils which exhibit exceptional load-carrying capacity by use of a synergistic combination of sulfur (S)-based and phosphorous (P)-based load additives. The S-containing additive of the present invention is sulfurized fatty acid (SFA), preferably the sulfurized oleic acid (SOA) and the P-containing additive is one or more amine phosphate(s). The turbo oil composition consisting of the dual P/S additives of the present invention achieves an excellent load-carrying capacity, which is better than or equivalent to that obtained when each additive was used alone at a treat rate higher than the total additive combination treat rate, and this lower additive concentration requirement allows the turbo oil composition to meet or exceed U.S. Navy MIL-L-23699 requirements including Oxidation and Corrosion Stability and Si seal compatibility.
