Definitions
- the present invention relates to a new fuel composition
- a new fuel composition comprising oxygenated compounds improving the combustion of fuel, in particular compounds which can improve the cetane number of fuel bases such as middle distillates used in the composition of gas oils for diesel engines.
- a fuel base is generally constituted by a physical mixture of several middle distillates or petroleum fractions resulting from the refining of crude oils originating from all walks of the world. These petroleum fractions come from a large number of separations by atmospheric or vacuum distillation and from chemical transformations of some of these distilled cuts by hydrodesulfurization and or catalytic cracking. By an appropriate mixture of these different refined cuts, a large variety of fuel bases with relatively different physicochemical properties is obtained. Finally, diesel or diesel fuels usable in combustion engines are prepared by a complex mixture of these bases. However, to obtain fuels that meet current legal specifications, refiners must develop increasingly complicated formulations that favor crude oils with a high concentration of distillates and fuel bases with a high cetane number.
- the additives that is to say the compounds introduced at low contents into the refined cuts
- nitrates or organic peroxides which it is known that they have a limited effectiveness in fuel bases or gas oils naturally having a low cetane number.
- the organic peroxides decompose irreversibly as a function of time, which leads to a deterioration in the characteristics of the diesel fuel stored both in terms of quality and of cetane number.
- Refiners have long been looking for other sources of compounds which can make it possible to improve the cetane number of fuel bases and diesel fuels, in particular among oxygenated compounds such as ethers, polyethers or even acetals.
- oxygenated compounds such as ethers, polyethers or even acetals.
- the addition of oxygenated compounds in diesel fuels makes it possible to reduce the emission of pollutants, in particular the emission of particles (EP 14.992).
- US Pat. No. 5,308,365 claims the addition of 1 to 30% by weight of dialkylated and trialkylated derivatives of glycerin, obtained by adding an olefin such as isobutene to glycerol, in a gas oil having a range of use between 160 ° C and 370 ° C and a sulfur content less than or equal to 500 ppm.
- Patent JP 0725 8661 claims a formulation comprising 20 to 94% of a diesel cut having a distillation range between 130 ° C and 400 ° C, 5 to 40% of a hydrocracked diesel cut commonly called LCO and 1 to 40 % of a monoether of formula R 1 OR 2 in which R ⁇ and R 2 are alkyl chains of 3 to 12 carbon atoms.
- Patent JP 0701 8271 claims gas oils containing ether glycols of formula R 1 - (OA) n -R 2 in which R is an alkyl chain of 1 to 10 carbon atoms, R 2 represents the hydrogen atom or a alkyl chain comprising from 1 to 10 carbon atoms, A is of ethylene or trimethylene structure optionally substituted and n is an integer varying from 1 to 10.
- Patent JP 0634 0886 claims the addition to a diesel of 0.05% to 20% by weight of a compound of general formula Ri-O- (EO) n - (PO) m -R 2 in which R x and R 2 represent independently the hydrogen atom or an alkyl chain comprising from 1 to 20 carbon atoms, EO and PO representing respectively the oxyethylene and oxyisopropylene groups, and, m and n are integers between 0 and 15.
- Ri-O- (EO) n - (PO) m -R 2 in which R x and R 2 represent independently the hydrogen atom or an alkyl chain comprising from 1 to 20 carbon atoms, EO and PO representing respectively the oxyethylene and oxyisopropylene groups, and, m and n are integers between 0 and 15.
- patent FR 2,544,738 claims, as a component of diesel fuels, acetals of formula C 4 Hg-0-CR 1 R2-0-C H9 R- j _ and R which may be hydrogen or an alkyl group.
- the present invention relates to the use of a new family of oxygenated compounds in diesel fuels, which make it possible to increase the cetane index, to provide greater flexibility in the formulation of diesel fuels for a lower cost and also make it possible to limit the aromatic and sulfur compounds responsible for the emission of particles.
- the present invention therefore relates to a fuel composition comprising a major part of at least one fuel base and a minor part of at least one oxygenated compound characterized in that it contains at least 0.05% by weight of at least one trialkoxyalkane of general formula (I) below:

- R being a hydrogen atom or a linear alkyl radical comprising from 1 to 4 carbon atoms, R possibly even forming, by bond with a hydrocarbon residue of X, a ring comprising from 5 to 6 carbon atoms.
