  • Patent number: 10611969
    Abstract: Flash chemical ionizing pyrolysis (FCIP) at 450° C.-600° C. forms liquid ionizing pyrolyzate (LIP) that can be blended in oil feedstock for thermal processes to promote conversion of heavier hydrocarbons to reduce resid/coke yields and/or increase yields of liquid hydrocarbons and isomerates. A front-end refinery process modifies crude oil with LIP for distillation to reduce resid/coke yields and/or increase liquid oil yields. A downstream process modifies a heavy oil stream such as resid with LIP and the LIP-modified stream can be thermally processed to reduce resid/coke yields and/or increase liquid oil yields. FCIP of the LIP blends also improves quality and/or yields of the liquid pyrolyzate product. Finely divided FCIP solids can contain FeCl3 supported on NaCl-treated calcium bentonite. A process for preparing the FCIP solids treats iron with HCl and HNO3 to form acidified FeCl3 of limited solubility, loads the FeCl3 on NaCl-treated bentonite, and heat-treats the material at 400° C.-425° C.

  • Patent number: 9163297
    Abstract: Method of combining industrial processes having inherent carbon capture and conversion capabilities offering maximum flexibility, efficiency, and economics while enabling environmentally and sustainably sound practices. Maximum chemical energy is retained throughout feedstock processing. A hybrid thermochemical cycle couples staged reforming with hydrogen production and chlorination. Hydrogen generated is used to upgrade feedstocks including bitumen, shale, coal, and biomass. Residues of upgrading are chlorinated, metals of interest are removed, and the remainder is reacted with ammonia solution and carbon dioxide to form carbonate minerals. The combination provides emissions free production of synthetic crude oil and derivatives, as well as various metals and fertilizers. Sand and carbonate minerals are potentially the only waste streams. Through this novel processing, major carbon dioxide reduction is afforded byminimizing direct oxidation.

    Abstract: Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by hydrotreating the feed under mild conditions, and separating the hydrotreated effluent into an aromatic-rich fraction which contains a substantial amount of the aromatic refractory and sterically hindered sulfur-containing compounds, and an aromatic-lean fraction. The aromatic-rich fraction is contacted with isomerization catalyst, and the isomerized aromatic-rich fraction is recycled to the mild hydrotreating process.

  • Publication number: 20140291202
    Abstract: Methods are provided for dewaxing a distillate fuel boiling range feed to improve one or more cold flow properties of the distillate fuel feed, such as cloud point, with reduced consumption of hydrogen during the dewaxing process. The reduced hydrogen consumption is achieved by using a dewaxing catalyst with a reduced content of hydrogenation metals, such as a content of Pt or Pd of from about 0.03 wt % to about 0.35 wt %. A distillate fuel feed can be dewaxed to achieve a desired cloud point differential using a reduced metals content dewaxing catalyst under the same or similar conditions to those required for a dewaxing catalyst with higher metals content.

  • Patent number: 8834706
    Abstract: The present invention relates to a method for preparing lubricating base oils by using vacuum distilled deasphalted oil, and more specifically, to a method for preparing various kinds of lubricating base oils by distilling a distillate obtained from a solvent deasphalting (SDA) process under reduced pressure to obtain heavy deasphalted oil (H-DAO) and light deasphalted (Lt-DAO) and then treating the H-DAO and the Lt-DAO by catalytic reactions, respectively. According to the present invention, it is possible to obtain heavy lubricating base oil (150BS) of a high viscosity grade which can not be obtained by a known catalytic reaction and a lubricating base oil of group III by hydrogenation, in a high yield, and thus economical efficiency is excellent.

  • Patent number: 8828217
    Abstract: Diesel fuel is produced from a feedstock that is at least partially biocomponent in origin. A feedstock is treated in a reactor including one or more hydrotreating zones having a continuous gas phase. The liquid effluent from the hydrotreating zones is then hydroprocessed in a hydroprocessing zone having a continuous liquid phase, such as a hydroprocessing zone in the same reactor. The hydroprocessing zone can be operated under effective catalytic dewaxing conditions.

  • Patent number: 8828218
    Abstract: This invention provides methods for multi-stage hydroprocessing treatment of FCC naphthas for improving the overall production quantity of naphtha boiling-range materials during naphtha production for low sulfur gasolines. Of particular benefit of the present processes is the selective treating of cat naphthas to remove gums instead of undercutting the overall naphtha pool by lowering the end cutpoints of the cat naphtha fraction. This maximizes the amount of refinery cat naphtha that can be directed to the gasoline blending pool while eliminating existing processing problems in hydrodesulfurization units. The processes disclosed herein have the additional benefit of minimizing octane losses in the increased naphtha pool volume.

  • Publication number: 20140221712
    Abstract: Integrated processes for upgrading crude shale-derived oils, such as those produced by oil shale retorting or by in situ extraction or combinations thereof. Processes disclosed provide for a split-flow processing scheme to upgrade whole shale oil. The split flow concepts described herein, i.e., naphtha and kerosene hydrotreating in one or more stages and gas oil hydrotreating in one or more stages, requires additional equipment as compared to the alternative approach of whole oil hydrotreating. While contrary to conventional wisdom as requiring more capital equipment to achieve the same final product specifications, the operating efficiency vis a vis on-stream time efficiency and product quality resulting from the split flow concept far exceed in value the somewhat incrementally higher capital expenditure costs.
