Definitions
- the present invention relates to a fuel containing a creaminess additive to improve lubricating properties of fuels, whether diesel or aviation fuel (jet fuel), and more particularly of low-content diesel fuels in sulfur.
- additives containing dimer acids such as those containing trimer acids, cannot be used in fuels for vehicles in which the fuel may come into contact with lubrication because these acids form by chemical reaction deposits that are sometimes insoluble in oil, but above all incompatible with commonly used detergents.
- US Patent 4,609,376 recommends the use anti-wear additives obtained from acid esters mono- and poly-carboxylic and polyhydric alcohols in fuels containing alcohols in their composition.
- US Patent 2,686,713 recommends the introduction of tall oil up to 60 ppm in diesel fuels to prevent rust from forming on surfaces metal in contact with these fuels.
- esters vegetable oils or the vegetable oils themselves in these fuels are also chosen route.
- esters vegetable oils or the vegetable oils themselves in these fuels are also chosen route.
- One of the major drawbacks of these esters is their low lubricity at a concentration of less than 0.5% by weight in fuels.
- patent application WO 95/33805 recommends the introduction of a cold-keeping additive consisting of nitrogenous additives comprising one or more NR 13 groups in which R 13 comprises from 12 to 24 atoms carbon, is linear, slightly branched or alicyclic and aromatic, the nitrogen group which can be linked by CO or CO 2 and form amine carboxylates or amides.

- the acid is preferred. abietic, dihydroabietic acid, acid tetrahydroabietic, dehydroabietic acid, acid neoabietic, pimaric acid, levopimaric acid and parastrinic acid and their derivatives.
- the polycyclic hydrocarbon compound of said combination is a hydrocarbon compound of formula (II) below; in which at most one X in each cycle is a heteroatom such as nitrogen or oxygen, the other X being carbon atoms, in which R 1 , R 2 , R 3 and R 4, identical or different, are either a hydrogen atom or hydrocarbon groups, each connected to at least one atom from one of the two rings, these hydrocarbon groups being chosen from alkyl groups comprising from 1 to 5 atoms, aryl groups, hydrocarbon rings of 5 to 6 atoms, optionally containing a heteroatom such as oxygen or nitrogen, each ring being formed by direct connection of two groups R i chosen from R 1, R 2 , R 3 and R 4 , optionally via a hetero atom, the said ring being saturated or unsaturated, unsubstituted or substituted by an optionally olefinic aliphatic radical comprising from 1 to 4 carbon atoms, and Z, connected to at least one atom from
- the aliphatic hydrocarbon monocarboxylic is in the form of acid, carboxylate amines and esters.
- the combination comprises from 1 to 50% by weight of at least one compound corresponding to at least one of the formulas (I) and (II), and from 50 to 99% by weight of at least one acid linear monocarboxylic, saturated or unsaturated, comprising 12 to 24 carbon atoms, these products being present under form of acid, carboxylate of amines or esters.
- amine carboxylates By amine carboxylates is meant the compounds resulting from the reaction of these acids with amines or primary, secondary and tertiary polyamines including from 1 to 8 carbon atoms per chain and the alkylene amines and primary, secondary or tertiary alkylene polyamines comprising from 2 to 8 carbon atoms.
- these amine salts are derived from selected amines in the group consisting of ethyl-2-hexylamine, N, N-dibutylamine, ethylenediamine, diethylenetriamine and tetraethylenepentamine.
- alkanol esters are preferred primary with 1 to 8 carbon atoms or polyalcohols from the group consisting of ethylene glycol, propylene glycol, glycerol, trimethylolpropane, pentaerythritol, diethanolamine, triethanolamine and their derivatives.
- the fuel contains 50 to 1000 ppm of the oiliness additive.
- additives usually added in such fuels such as detergent additives, additives improving the index of cetane, demulsifying additives, anti-corrosion additives, additives improving cold coming, and odor modifying additives.
- This example describes the choice of additives in function of their solubility in a weak diesel sulfur.
- Each additive in test is diluted to 5% by weight in a diesel (GO) at 500 ppm sulfur, at room temperature.
- additives according to the invention are designated by Y and by C the comparative examples in Table I below.
- Additives Y consist, on the one hand, of a mixture of a combination of fatty acids containing by weight 50 to 55% oleic acid, 30 to 40% linoleic acid, 3 to 5% palmitic acid and 1 with 2% linolenic acid, and for another part in resin acids obtained by distillation of tall oil, by-product of the manufacture of wood pulp by the sulphate process.
- C 1 corresponds to pure oleic acid
- C 2 to rosin which is a mixture of resin acids corresponding to the distillation residue of pine gems
- C 3 is a mixture of dimer acids obtained by thermal dimerization and / or catalytic of unsaturated fatty acids.
- the test consists in imposing jointly with a ball of steel in contact with a stationary metal plate, a pressure corresponding to a weight of 200 g and a displacement alternating 1 mm at a frequency of 50 Hz.
- the ball in movement is lubricated by the composition to be tested.
- the temperature is maintained at 60 ° C for the duration of the test, i.e. 75 min.
- the lubricity is expressed as the average value of the footprint diameters wear of the ball on the plate.
- a small diameter wear generally less than 400 ⁇ m indicates good lubricity; conversely, a wear diameter important (greater than 400 ⁇ m) translates a power of as much more insufficient than the value of the wear diameter is high.
- Example I studies the compatibility of additives described in Example I with lubricants usually used in diesel engines according to the protocol described below.
- the additives of the invention, Y 1 and Y 2 give no deposit or cloudiness when the diesel fuel with 100 ppm additive is added to the oil.
- the purpose of this example is to describe additives oiliness adapted to be introduced into fuels according to the invention.
- amine carboxylates obtained by simple mixing at room temperature and at atmospheric pressure of Y 1 with an amine or polyamine according to the invention, thus allowing the neutralization of the carboxylic sites.
