Abstract
A marine fuel blend comprising renewable hydrotreated fuel is disclosed. The present marine fuel blend is environmentally friendly and has good pour point and storage stability.
Claims15
A marine fuel blend comprising:
- DMB type or RMB type marine fuel having a density between 860 and 960 kg/m3 at 15° C.;
- and
- 0.5-50 vol-% renewable hydrotreated fuel, wherein the renewable hydrotreated fuel includes paraffinic components in a carbon number range C15-C18, said paraffinic components constituting at least 70 vol-% of the renewable hydrotreated fuel;
- and
- wherein the marine fuel blend has a pour point which is at least 3° C. lower than a calculated pour point expressed as a weighted average of pour points of the marine fuel and the renewable hydrotreated fuel.

Method of manufacturing a marine fuel blend, the method comprising:
- providing a DMB type or RMB type marine fuel having a density between 860 and 960 kg/m3 at 15° C.;
- selecting from a range 0.5-50 vol-% an amount of renewable hydrotreated fuel which provides a pour point which is at least 3° C. lower than a calculated pour point of the marine fuel blend;
- and
- blending the marine fuel with the selected amount of renewable hydrotreated fuel;
- wherein the renewable hydrotreated fuel contains paraffinic components in a carbon number range C15-C18, said paraffinic components constituting at least 70 vol-% of the renewable hydrotreated fuel, and the hydrotreated fuel being manufactured by deoxygenation, denitrogenation and desulphurisation of fatty acids, triglycerides and other fatty acid derivatives by hydrotreatment.
