Abstract
The invention relates to a marine fuel composition comprising additivated CNSL and an improved cetane number. The composition comprises: - 65% to 99% by mass of a first component (a) comprising a fossil base, this first component having a sulfur content of at most 1.5% by mass, preferably of at most 1% by mass, more preferably of at most 0.7% by mass, and a flash point of at least 60°C, - 1% to 35% by mass of a second component (b) consisting of cashew nut shell liquid (CNSL), - 500 to 5000 ppm by mass of an additives composition (c) with respect to the sum of the masses of components (a) and (b), said additives composition (c) comprising: (i) one or more cetane improver additives, (ii) one or more deposit reducing additives.
