  • Patent number: 12129440
    Abstract: The invention relates to jet fuel compositions, in particular jet fuel compositions having improved cold properties, and more particularly improved freezing point with respect to theoretical linear behavior, which are mixtures of jet fuel from petroleum origin and renewable component. To this effect, a jet fuel composition comprising a petroleum derived jet fuel component and a renewable component consisting of hydroprocessed esters and fatty acids is proposed, wherein the jet fuel composition contains 1 to 50 vol % of the renewable component and has a freezing point of ?40° C. or below, preferably of ?47° C. and below, and the petroleum derived jet fuel component has a content of C9-C12 normal paraffins from 17 wt % to 30 wt %.

  • Patent number: 11920096
    Abstract: Low sulfur fuel oil blend compositions and methods of making such blend compositions to increase the stability and compatibility of LSFO blends having paraffinic resids that are blended with distillates and/or cracked stocks of higher asphaltenes and/or aromatics content. In one or more embodiments, distillates and/or cracked stocks that incrementally reduce the initial aromaticity of the distillate or cracked stock with the highest aromaticity are sequentially blended prior to resid addition. Such incremental reduction and sequential blending have been found to provide a resulting low sulfur fuel oil blend that is both compatible and stable.

  • Patent number: 11905479
    Abstract: Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.

  • Patent number: 11692147
    Abstract: For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. Marine shipping use of high sulfur bunker oils is reported as largest source of worldwide transportation SOx emissions. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can use these fuels to generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.

  • Patent number: 11485920
    Abstract: Hydroprocessed residual fuel and/or fuel blending components are provided that have a sulfur and nitrogen level comparable to liquefied natural gas (LNG). Because of the low starting level of sulfur and/or nitrogen, the severity of the hydroprocessing that is needed for the crude oil or bottoms fraction in order to remove sulfur to a level that is comparable to LNG is reduced or minimized. This can allow the resulting marine residual fuels to have low carbon intensity, low SOx and NOx emission and high energy density. Since the hydroprocessed fractions correspond to a fuel oil product, the resulting marine fuel can be used in existing fleets, and can be distributed in existing bunkering systems.

  • Patent number: 9005428
    Abstract: The present invention is directed to the upgrading of heavy hydrocarbon feedstock that utilizes a short residence pyrolytic reactor operating under conditions that cracks and chemically upgrades the feedstock. The process of the present invention provides for the preparation of a partially upgraded feedstock exhibiting reduced viscosity and increased API gravity. This process selectively removes metals, salts, water and nitrogen from the feedstock, while at the same time maximizes the yield of the liquid product, and minimizes coke and gas production. Furthermore, this process reduces the viscosity of the feedstock in order to permit pipeline transport, if desired, of the upgraded feedstock with little or no addition of diluents.
