Abstract: Marine fuel compositions that are low sulfur and have improved wax flow viscosity are disclosed. An example marine fuel composition may have the following enumerated properties: a sulfur content of about 0.50% or less by weight of the marine fuel composition; a density at 15° C. of about 0.86 g/cm3 to about 1.01 g/cm3; a kinematic viscosity at 50° C. of about 1 centistoke to about 700 centistokes; and a ratio of kinematic viscosity to wax flow viscosity of greater than 1, wherein the wax flow viscosity is determined using a minimum operating viscosity of about 8 centistokes at 50° C.

Abstract: Compositions corresponding to marine diesel fuels, fuel oils, jet fuels, and/or blending components thereof are provided that include at least a portion of a natural gas condensate fraction. Natural gas condensate fractions derived from a natural gas condensate with sufficiently low API gravity can provide a source of low sulfur, low pour point blend stock for formation of marine diesel and/or fuel oil fractions. Natural gas condensate fractions can provide these advantages and/or other advantages without requiring prior hydroprocessing and/or cracking.

Abstract: Heavy hydrotreated gas oil compositions are provided, along with marine fuel oil compositions and marine gas oil compositions that include a substantial portion of a hydrotreated heavy atmospheric gas oil. The hydrotreated heavy atmospheric gas oil can correspond to a gas oil with a relatively low viscosity and an elevated paraffin content in a narrow boiling range which results in a relatively high cloud point and/or pour point.

Abstract: Systems and methods are provided for upgrading catalytic slurry oil to form naphtha boiling range and/or distillate boiling range fuel products. It has been unexpectedly discovered that catalytic slurry oil can be separately hydroprocessed under fixed bed conditions to achieve substantial conversion of asphaltenes within the slurry oil (such as substantially complete conversion) while reducing or minimizing the amount of coke formation on the hydroprocessing catalyst. After hydroprocessing, the hydroprocessed effluent can be processed under fluid catalytic cracking conditions to form various products, including distillate boiling range fuels and/or naphtha boiling range fuels. Another portion of the effluent can be suitable for use as a low sulfur fuel oil, such as a fuel oil having a sulfur content of 0.1 wt % or less.

Abstract: This disclosure relates to compositions and methods of making an additized fuel composition comprising a base fuel composition and a randomly branched nitrate composition. The randomly branched nitrate composition includes a plurality of primary nitrate molecules, each molecule therein having an empirical chemical formula of CnNO3, wherein Cn is a branched aliphatic moiety which may be the same or different for each molecule, n is an integer selected from the group consisting of 8, 9, 10, 11 and 12, at least one carbon atom in the branched aliphatic moiety being bound to three or more carbon atoms, a branching index ranging from 1.8 to 2.2, and greater than 80% of the branches in the aliphatic moiety being in other than the alpha position. The additized fuel composition may be diesel fuel composition or a gasoline fuel composition.

Abstract: Marine diesel fuel/fuel blending component compositions and fuel oil/fuel blending component compositions are provided that are derived from crude oils having high naphthenes to aromatics volume and/or weight ratios and a low sulfur content. In addition to having a high naphthenes to aromatics ratio, a low sulfur content, and a low but substantial content of aromatics, such fuels and/or fuel blending components can have a reduced or minimized carbon intensity relative to fuels derived from conventional sources. The unexpected ratio of naphthenes to aromatics contributes to the fuels and/or fuel blending components further having additional unexpected properties, including low density, low kinematic viscosity, and/or high energy density.

Abstract: Fuels and/or fuel blending components can be formed from hydroprocessing of high lift deasphalted oil. The high lift deasphalting can correspond to solvent deasphalting to produce a yield of deasphalted oil of at least 50 wt %, or at least 65 wt %, or at least 75 wt %. The resulting fuels and/or fuel blending components formed by hydroprocessing of the deasphalted oil can have unexpectedly high naphthene content and/or density. Additionally or alternately, the resulting fuels and/or fuel blending components can have a clear and bright appearance.
