Definitions
- This invention relates to low sulphur gasoline compositions which have improved response to friction reducing additives.
- Fuels such as gasolines and diesels are used rather widely in automotive transport and for providing power for heavy duty equipment, especially diesels due to their high fuel economy.
- one of the problems when such fuels are burned in internal combustion engines is their low lubricity. This reduction in lubricity arises because as the sulphur content in the fuel is reduced eg by hydrodesulphurisation, this process also incidentally removes the lubricity providing polar or friction reducing molecules such as eg the nitrogenous compounds present in such fuels.
- SAE Paper No. 962010 by Wei Dan Ping et al entitled “Comparison of the Lubricity of Gasoline and Diesel Fuels” (1996) describes the effects of various additives on such fuels including low sulphur fuels.
- EP-A-0860494, EP-A-0739970 and EP-A-0635558 relate to low sulphur diesel, gas oils and gas oils (diesel fuels) respectively containing esters derived by transesterification of vegetable oils, glycerol/fatty acid esters and lower alkyl esters of a mixture of saturated and unsaturated fatty acids derived from oleaginous seeds respectively as a lubricity improving agent.
- low sulphur gasolines especially gasolines having a sulphur content of ⁇ 30 ppm.
- WO99/00467 describes a fuel composition of improved lubricity comprising a spark ignition fuel and an alkanolamide of a fatty acid or a modified fatty acid having a maximum sulphur content of 0.05% based on mass.
- gasolines are mentioned and all of the examples relate to diesels, especially Swedish Class I low sulphur diesel fuel.
- bromine number or UV absorbance of the fuels tested or claimed is also no reference to the bromine number or UV absorbance of the fuels tested or claimed. It has now been found that the efficacy of the friction reducing additives can be significantly improved by mixing the same with fuels of specific, predetermined characteristics.
- the present invention is a composition
- a low sulphur gasoline having a sulphur content of less than 30 ppm, a bromine number of less than about 10 and an ultraviolet absorbance at 319 nm below 0.15 and (ii) an effective amount of an ashless friction reducing additive which is a fatty acid having 10-30 carbon atoms or a derivative thereof.
- the gasoline should have a bromine number (which is related to the amount of olefins in the fuel) below 10, suitably below 5 and preferably below 4.5. Furthermore, the gasoline should have a sulphur content below 30 ppm, suitably below 20 ppm and preferably below 10 ppm. Again the UV absorbance of the fuel at 319 nm should be below 0.1 , suitably below 0.07 and preferably below 0.05.
- the ashless friction reducing additive in the composition is suitably a liquid at room temperature and pressure and is selected from C10-C30 fatty acids, preferably a C10-C24 fatty acid, or a derivative thereof and mixtures thereof.
- Such ashless friction reducing additives are suitably derived from naturally occurring fats and oils and the preferred derivatives are suitably selected from the alkylamine salts, alkyl amides and alkyl esters of such acids and oligomers thereof.
- An example of an alkyl amine carboxylate salt is n- butylamine oleate or a derivative thereof and an example of a naturally occurring fatty acid is a substance comprising a fatty acid, a tall oil fatty acid or derivatives thereof.
- n-Butylamine oleate has the formula:
- n-butylamine oleate is commercially sold as a friction modifier as RS124 by Bitrez Ltd.
- the substance comprising fatty acids may be either 100% fatty acids, or substantially 100% fatty acids, or may be a mixture of fatty acids and/or tall oil acids or derivatives thereof. Such a mixture suitably contains at least 30% w/w, preferably at least 50% w/w of fatty acids.
- An example of a suitable commercially available substance containing fatty acids is TOLAD® 9103 (ex Baker-Petrolite Ltd).
- the friction reducing additive is used in an amount sufficient to provide effective lubricity to the composition.
- the friction reducing additive is suitably used in an amount of less than 1000 mg per kilogram of base fuel in the composition, preferably from 1 to 500 mg and more preferably from about 5 to 100 mg per kg of base fuel in the composition.
- the ashless friction reducing additive may be part of an additive concentrate comprising a number of additives.
- the amount of the friction reducing additive is suitably from 0.2-25% w/w, preferably from 0.5-20% w/w and more preferably from 3 to 15% w/w.
- the treat level of the friction reducing additive in the gasoline is suitably from 4-200 ppm, preferably from 10-100 ppm and more preferably from 25-75 ppm.
