Abstract: Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

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: Methods are provided for treatment of kerosene/jet fuel boiling range fractions, such as previously qualified jet fuel fractions, to allow blending of the kerosene/jet fuel boiling range fractions to produce a jet fuel boiling range blend having a breakpoint that is equal to or greater than the breakpoint of at least one of the kerosene jet fuel boiling range fractions used to form the blend. The breakpoint of the jet fuel boiling range blend can be maintained by treating at least one of the component fractions of the blend and/or by treating the blend to reduce a nitrogen content. The reduced nitrogen content can correspond to a reduced content of total nitrogen and/or a reduced content of unexpected nitrogen compounds.

Abstract: The present technology provides compositions that include at least about 98 weight percent (“wt %”) n-paraffins which, among other surprising features, may be suitable for use as a diesel fuel, an aviation fuel, a jet fuel blendstock, a blendstock to reduce the cloud point of a diesel fuel, a fuel for portable heaters, and/or as a charcoal lighter fluid. The composition includes at least about 98 wt % C7-C12 n-paraffins, where at least about 10 wt % of composition includes n-decane, at least about 20 wt % of the composition includes n-dodecane, and at least about 75 wt % of the composition includes even carbon number paraffins.
