US Patent 10457881 Fuel compositions

Low sulphur marine fuel compositions are provided. Embodiments comprise greater than 50 to 90 wt % of a residual hydrocarbon component comprising at least one of an atmospheric tower bottoms (ATB) residue and a vacuum tower bottoms residues (VTB), wherein the residual hydrocarbon component has a kinematic viscosity at ˜50 degrees C. of at least 100 cSt; and at least 10 and up to 50 wt % of a non-hydroprocessed hydrocarbon component comprising deasphalted oil (DAO), where the marine fuel composition has a kinematic viscosity at ˜50 degrees C. of at least 10 cSt. Embodiments of the marine fuel composition can have a sulphur content of about 0.1 wt % or less.
