  • Patent number: 9309471
    Abstract: Embodiments of methods for purifying a biomass-derived pyrolysis oil are provided. The method comprises the step of contacting the biomass-derived pyrolysis oil with a first deoxygenating catalyst in the presence of hydrogen at first predetermined hydroprocessing conditions to form a first low-oxygen biomass-derived pyrolysis oil effluent. The low-oxygen biomass-derived pyrolysis oil effluent is contacted with an ionic liquid to remove phenolic compounds, nitrogen compounds and other impurities. This ionic liquid step may be followed by a second deoxygenation step or the deoxygenating may be completed and then followed by the ionic liquid purification step.

  • Patent number: 8986537
    Abstract: Provided are multiple correlations for relationships between MI value for a brightstock extract and the distillation cut point temperature used for separation of the vacuum resid that is used to form the brightstock extract. Based on these correlations, a BSE having a desired MI value can be formed based on an adjustment of the distillation cut point temperature. A first correlation establishes a relationship between a fractional weight boiling temperature for a vacuum resid fraction and a distillation cut point temperature for separating the vacuum resid fraction from at least one distillate fraction in a feedstock. A second correlation establishes a relationship between a fractional weight boiling temperature for a brightstock extract derived from the vacuum resid fraction, and the fractional weight boiling temperature for the vacuum resid fraction. A third correlation has been established between the fractional weight boiling temperature for the brightstock extract and a mutagenicity index value.

  • Publication number: 20120055844
    Abstract: A method and apparatus for recovering components from a hydrocarbon feedstock is provided. The method includes the steps of (a) supplying a hydrocarbon feedstock to an oxidation reactor, wherein the hydrocarbon feedstock is oxidized in the presence of a catalyst under conditions sufficient to selectively oxidize sulfur compounds and nitrogen compounds present in the hydrocarbon feedstock; (b) separating the hydrocarbons, the oxidized sulfur compounds, and the oxidized nitrogen compounds by solvent extraction; (c) collecting a residue stream that includes the oxidized sulfur compounds and the oxidized nitrogen compounds; and (d) supplying the residue stream to a fluid catalytic cracking unit.

  • Patent number: 7981277
    Abstract: A method for dewatering and deasphalting a hydrocarbon feed is provided. A hydrocarbon feed containing one or more hydrocarbons, asphaltenes and water can be mixed or otherwise combined with one or more solvents. The addition of the solvent sufficiently decreases the density of the hydrocarbon feed to enable gravity settling of the water phase, providing an oil phase containing one or more hydrocarbons, asphaltenes and solvents. The asphaltenes can be separated from the oil phase to provide an asphaltene mixture containing asphaltenes and a portion of the solvents and a deasphalted oil containing one or more hydrocarbons and the balance of the solvents. The solvents can be separated from the asphaltenes and deasphalted oil, and recycled to the initial mixing step wherein the solvent is mixed or otherwise combined with one or more solvents.

  • Publication number: 20110155635
    Abstract: A process for removing a metal from a resid feed includes contacting the resid feed comprising the metal with a resid-immiscible ionic liquid to produce a resid and resid-immiscible ionic liquid mixture, and separating the mixture to produce a resid effluent having a reduced metal content relative to the resid feed.

  • Patent number: 7868214
    Abstract: A process for producing olefins from a feedstock comprising a petroleum and non-petroleum fraction has been developed. The process comprises first pretreating the feedstock to remove contaminants such as alkali metals and then cracking the purified feedstock in a fluidized catalytic cracking (FCC) zone operated at conditions to provide C2-C5 olefins. Alternatively, the non-petroleum fraction can first be treated and then mixed with petroleum fraction to provide the feedstock which is then catalytically cracked.

  • Publication number: 20100264065
    Abstract: The process of the present invention is directed to the desulfurization of a sulfur-containing unrefined hydrocarbon stream with a membrane separation apparatus, where sulfur compounds are concentrated in a sulfur-rich stream on a permeate side of the membrane, and a sulfur-lean stream is recovered as a retentate. The sulfur-rich stream, which has a small volume relative to the original unrefined hydrocarbon stream, is conveyed to a subsequent desulfurization apparatus or system, such as a hydrotreating system, to recover the hydrocarbons associated with the organosulfur compounds. The stream desulfurized by conventional processes, such as hydrotreating, and the hydrocarbons desulfurized by the membrane separation apparatus may be combined to provide a low sulfur hydrocarbon effluent with minimal or no loss of the original volume.

  • Publication number: 20100200461
    Abstract: A highly effective liquid-liquid extraction process to remove nitrogen compounds and especially basic nitrogen compounds from aromatic light petroleum oils with excellent recovery employs de-ionized water, which can be acidified, as the extractive solvent. The product is an aromatic hydrocarbon with ultra-low amounts of nitrogen poisons that can deactivate acidic catalysts. The extracted oils are suitable feedstock for the subsequent catalytic processes that are promoted with the high performance solid catalysts, which are extremely sensitive to nitrogen poison.

  • Patent number: 7744743
    Abstract: A feedstream comprising tar is fed to a solvent deasphalter wherein it is contacted with a deasphalting solvent or fluid to produce a composition comprising a mixture or slurry of solvent containing a soluble portion of the tar, and a heavy tar fraction comprising the insoluble portion of the tar. These fractions may be separated in the deasphalter apparatus, such as by gravity settling wherein the heavy tar fraction is taken off as bottoms, and the solvent-soluble fraction taken as overflow or overheads with the solvent. The overflow or overheads is sent to a solvent recovery unit, such as a distillation apparatus, wherein solvent is recovered as overheads and a deasphalted tar fraction is taken off as a sidestream or bottoms. The solvent or a portion thereof, recovered as overheads, may be then be recycled to the solvent deasphalter, or in a preferred embodiment, at least a portion of the solvent is steam cracked to produce a product comprising light olefins.
