  • Publication number: 20210032546
    Abstract: Hydrocracked bottoms fractions are treated to separate HPNA compounds and/or HPNA precursor compounds and produce a reduced-HPNA hydrocracked bottoms fraction effective for recycle, in a configuration of a single-stage hydrocracking reactor, series-flow once through hydrocracking operation, or two-stage hydrocracking operation. A process for separation of HPNA and/or HPNA precursor compounds from a hydrocracked bottoms fraction of a hydroprocessing reaction effluent comprises contacting the hydrocracked bottoms fraction with an effective quantity of a non-polar solvent to promote precipitation of HPNA compounds and/or HPNA precursor compounds. The soluble hydrocarbons in the hydrocracked bottoms fraction are separated into an HPNA-reduced hydrocracked bottoms portion that is recycled within hydrocracking operations.

  • Publication number: 20200400645
    Abstract: A method and system to determine mass fraction of aromatic hydrocarbons, sulfur-multi-sulfur, sulfur-nitrogen, multi-sulfur-multi-nitrogen, and nitrogen containing aromatic compound classes present within a petroleum sample. The invention uses total sulfur determination, total nitrogen determination, and elemental formulas determination, with the latter determined through time-of-flight mass spectrometric analysis with atmospheric pressure photo ionization and Fourier-transform ion-cyclotron resonance mass spectrometric analysis with atmospheric pressure photo ionization.

  • Publication number: 20200377451
    Abstract: Oxidized disulfide oil (ODSO) solvent compositions are derived from by-product disulfide oil (DSO) compounds produced as by-products from the generalized mercaptan oxidation (MEROX) processing of a refinery feedstock. The oxidized disulfide oil (ODSO) solvent compositions comprise at least a primary oxidized disulfide oil (ODSO) compound selected from either water soluble or water insoluble oxidized disulfide oil (ODSO) compounds and in some embodiments at least 0.1 ppmw of a secondary oxidized disulfide oil (ODSO) compound that is a water soluble oxidized disulfide oil (ODSO) compound.

  • Patent number: 10793782
    Abstract: Oxidized disulfide oil (ODSO) compounds, derived from by-product disulfide oil (DSO) compounds produced as by-products from the generalized mercaptan oxidation (MEROX) in the practice of the process, are effective as aromatic extraction solvents. This use of ODSO compounds as an extraction solvent converts an otherwise DSO waste oil product into a valuable commodity that has utility in improving the extraction of aromatics from hydrocarbons derived from fossil fuels.

  • Patent number: 10563138
    Abstract: The invention relates to a method for optimizing layered catalytic processes. This is accomplished by testing various catalysts with a compound found in a feedstock to be tested, to determine the facility of the catalyst in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, and hence the feedstock. In a preferred embodiment, the Double Bond Equivalence of the feedstock and molecule are determined, and catalysts are pre-selected based upon their known ability to work with materials of this DBE value. In preferred embodiments, the layered catalysts include a demetallization catalyst, used before hydrocracking. In additional preferred embodiments, the test feedstock contains 500 ppmw or less asphaltenes, preferably C5-asphaltenes.
