Fuel composition comprising a renewable base, a phenolic compound and a nitrogen-containing heterocyclic aromatic compound

Method for increasing the auto-ignition temperature of a fuel composition comprising:

• adding (a) at least 50% by mass, relative to the total mass of the fuel composition, of one or more factions of paraffinic hydrocarbons consisting of hydrogenated fatty acids, fatty acid esters (HEFA), and combinations thereof;
• adding (b) at least 0.05% by mass, relative to the total mass of the fuel composition, of one or more phenolic compounds corresponding to formula (I) below:
• in which the groups may be identical or different, represent, independently of each other, a hydrogen atom or a linear or branched alkyl group comprising from 1 to 16 carbon atoms;
• it being understood that at least one of the groups R1, R2, R3, R4 and R5 represents a linear or branched alkyl group comprising from 1 to 16 carbon atoms;
• and
• adding (c) at least 0.05% by mass, relative to the total mass of the fuel composition, of one or more nitrogen-containing heterocyclic aromatic compounds corresponding to formula (II) below:
• in which the groups may be identical or different, represent, independently of each other, a hydrogen atom or a linear or branched alkyl group comprising from 1 to 16 carbon atoms.

Method for increasing the eco-material content of a fuel composition, for fueling aircraft and rocket engines comprising:

• adding, to the fuel composition, one or more phenolic compounds corresponding to formula (I) below:
• in which the groups may be identical or different, represent, independently of each other, a hydrogen atom or a linear or branched alkyl group comprising from 1 to 16 carbon atoms;
• it being understood that at least one of the groups R1, R2, R3, R4 and R5 represents a linear or branched alkyl group comprising from 1 to 16 carbon atoms;
• and
• adding, to the fuel composition, one or more nitrogen-containing heterocyclic aromatic compounds corresponding to formula (II) below:
• in which the groups may be identical or different, represent, independently of each other, a hydrogen atom or a linear or branched alkyl group comprising from 1 to 16 carbon atoms.
