Definitions
- the present invention relates more specifically to the composition of fuels consisting of water / liquid hydrocarbon emulsions of water / diesel emulsions which are economically interesting and limit the problems of environmental pollution. So it's going to be in the present exposed water / hydrocarbon stabilized emulsions, including surfactants to promote and maintain the stable emulsion for variations in temperatures between -10 ° C and above 70 ° C.
- phase separation phase shift / demixing
- Out of phase oil (separated) at the end of this period may represent up to 3% by volume of the emulsion. It is easy to imagine that after a few days of storage, the phase shift of this emulsion according to the application No. 2,470,153 is sufficiently important for become unacceptable to operation, under normal conditions of application.
- the fuel emulsified according to this patent also suffers from a lack of stability, especially at low temperatures.
- the Applicant has also been able to this clearly evident by reproducing the preferred example of implementation of the emulsified fuel according to this US patent. It turned out that the emulsion separated (shift) in one hour. The phenomenon is further accentuated at low temperature less than 5 ° C. One can hardly imagine then, what could happen in Vehicle tanks containing this emulsion during a harsh winter.
- Japanese Patent Abstract No. 77-69,909 given in the chemical abstract 87: 138 513 x concerns an emulsified fuel (kerosene: water) comprising sorbitan sesquioleate and polyethylene glycol ether of nonylphenol as emulsifiers.
- the size of the dispersed phase droplets aqueous is ⁇ 20 ⁇ and on average of the order of 10 ⁇ .
- This technical proposal does not does not allow it to meet the stability objectives appropriately physicochemical, pollution control, economy and reduction of fuel consumption.
- This technical education can not be of any relief for a person skilled in the art who places himself in the prospective approach of the invention.
- emulsified fuels which can be fuels, include specific quantities of hydrocarbons and a set of additives minor amount, including an emulsifying system comprising at least one sorbitol ester, at least one polyalkoxylated fatty acid ester of higher HLB or equal to 9, and at least one alkylphenol-polyalkoxylated HLB of between 10 and 15, the respective concentration ratios of these components ranging from 2.5 - 3.5; 1.5 - 2.5; 0.5 - 1.9.
- the dispersed phase of these emulsified fuels is constituted 5 to 35% by weight of the water, while the additives are present at 0.1 to 2% by weight.
- the present invention aims at a stable emulsified fuel during the less than four days at more than 70 ° C, cold fuel stability, that is to say - 10 ° C or storage up to 40 ° C being maintained for at least three months without untimely decantation. In addition, it aims to obtain an emulsified fuel satisfactory to all levels of government in terms of the environment.
- the preferred sorbitol esters are selected from sorbitol oleates, taken alone or as a mixture, the sesquioleate of sorbitol having the preference.
- the fatty acid esters of formula (II) are chosen from oleates, stearates and ricinoleates of polyethylene glycol.
- the preferred esters are those whose polyethylene glycol fraction has a molecular weight less than or equal to 600, and preferably less than 450.
- the polyalkoxylated compounds of formula (III) which in combination with the other two components of the system emulsifying fuel stability when hot, are chosen from iso di and trialkyl alcohols, each alkyl radical having 1 to 15 carbon atoms, preferably among the alcohols Alkyl radicals comprise from 5 to 12 carbon atoms. Preferably they are chosen from isotridecyl alcohols comprising from 3 to 10 groups ethoxylates.
- the hydrocarbon liquid constituting the part major fuel is selected from the group consisting of species, middle distillates, synthetic fuels, animal or vegetable oils, esterified or not, and their mixtures.
- the emulsified fuel according to the invention also comprises the phase hydrocarbon, water and emulsifier system other additives such as procetanes chosen preferably from peroxides and / or nitrates and their mixtures, and optionally a metal catalyst for post-combustion so-called metal, being one of those of the group consisting of magnesium, calcium, barium, cerium, copper, iron or their mixtures. It can contain in in addition to the aqueous phase a biocide, preferably a bactericide and / or a fungicide, and also antifreeze.
- the fuel according to the invention may contain usual additives such as filterability additives, cloud point improvement, lubricant and anti-sedimentation additives, anti-wear additives, anti-foam additives, anti-corrosion additives, additives detergents, and / or additives or additive compositions to improve the operability to cold.
- additives such as filterability additives, cloud point improvement, lubricant and anti-sedimentation additives, anti-wear additives, anti-foam additives, anti-corrosion additives, additives detergents, and / or additives or additive compositions to improve the operability to cold.
- a second object of the invention is the composition of additives for fuel containing essentially the emulsifier system and possibly at minus another additive selected from compounds of the group consisting of procetanes, catalytic promoters of combustion and soot, biocides, anti-gels, detergents, lubricity additives, anti-foam additives, anti-corrosion additives, anti-wear additives and additives or additive compositions to improve cold operability.
- the purpose of this example is to present the stability results of the emulsified fuels of the invention compared to those of the known art.

- compositions A, C and F are compositions according to In the invention, compositions B, D, E and N serve as comparative examples.
- the quality of the emulsions were assessed according to criteria of granulometry, storage stability regardless of the ambient temperature, stability in use, storage stability and temperature stability.
- the stability of the emulsion in use is characterized by an absence of demixing / decantation or other disruption of the emulsion in a 1 liter beaker having undergoes a stimulating cycle corresponding to the presumed diesel recirculation cycle in a car tank.
- Storage stability is determined by an absence of demixing / decantation after three months of static storage in vials frustoconical sections of three samples maintained at 0 ° C, 20 ° C and 40 ° C, respectively.
- the demixion is characterized by the separation into two phases not necessarily clear.
- the hot stability is characterized by a total absence of demixing / settling after four days of static storage at 75 ° C.
- Stabilities are assessed by the more or less long time separating the preparation of the emulsion and the time of demixing / decantation. This time appraise according to the stability appreciated in hours (h), days (j), weeks (s) and months (M).
