Abstract

Low sulphur marine fuel compositions are provided. Embodiments comprise greater than 50 to 90 wt % of a residual hydrocarbon component, with the remaining 10 and up to 50 wt % selected from a non-hydroprocessed hydrocarbon component, a hydroprocessed hydrocarbon component, and a combination thereof. Embodiments of the marine fuel composition can have a sulphur content of about 0.1 wt % or less.
