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.
A resid-containing fraction comprising a T90 distillation point of 550° C. or more, a kinematic viscosity at 50° C. of 40 cSt to 180 cSt, a sulfur content of 0.2 wt % or less, a BMCI of 40 or less and a flash of 120° C. or more.
A fuel composition comprising 5 vol % to 60 vol % of a distillate fraction and 40 vol % to 95 vol % of a resid-containing fraction, the resid-containing fraction comprising a T90 distillation point of 550° C. or more, a kinematic viscosity at 50° C. of 40 cSt to 180 cSt, a sulfur content of 0.2 wt % or less, and a BMCI of 40 or less.
A method for forming a resid-containing fraction, comprising:
A resid-containing fraction comprising a micro carbon residue content of 2.5 wt % or less, a kinematic viscosity at 50° C. of 40 cSt to 180 cSt, a sulfur content of 0.2 wt % or less, a BMCI of 40 or less. and a flash point of 120° C. or more.
