Definitions
- the field of the present invention is that of fuel compositions, in particular, fuels intended for use in heat engines. More specifically, the fuels envisaged in the context of the invention mainly contain liquid hydrocarbons and in particular:
- the present invention is part of the approach, which has been in vogue for a long time, for the development of fuel compositions, in particular of fuels comprising substitutes for petroleum derivatives, in the interests of economy and limitation of pollution.
- Water quickly appeared as an interesting partial additive or substitute for petrol or diesel.
- Water is indeed an inexpensive and non-toxic liquid, which has been shown to reduce fuel consumption, as well as the emission of visible or invisible pollutants.
- no water, hydrocarbon fuel has hitherto been used industrially, on a large scale, in concrete applications, because of unacceptable difficulties of implementation and use.
- a first approach it has been envisaged to provide for the separate storage of water and fuel on the vehicle and their mixing at the time of use. This approach requires the installation on board the vehicle of a complex and sophisticated device for specific mixing and dosing. The cost, size and fragility of such devices appeared to be completely dissuasive for the development of this approach.
- the second apprehensible approach consists in using ready-made mixtures of water and fuel, but this was without taking into account the considerable problems of storage stability of such mixtures in temperature ranges varying from - 20 ° C to - 70 ° C, and stability under conditions of use of the emulsion in a tank.
- US Pat. No. 4,877,414 discloses an emulsified fuel comprising a number of additives, including an emulsifying system formed by sorbitan sesquioleate, sorbitan mono-oleate and polyoxyethylene ether ( 6 EO) of dodecyl alcohol.
- the total concentration of all additives is approximately 2.1%.
- the other additives that can be used can be: a mono- ⁇ -olefin (decene-1), methoxymethanol, toluene, alkyl benzene and calcium hydroxide. This formulation is extremely complex, if only by the number of additives used. It is also relatively expensive.
- the fuel emulsified according to this patent also suffers from a lack of stability, in particular at low temperature.
- the Applicant has moreover been able to clearly demonstrate this by reproducing the preferred example of implementation of the emulsified fuel according to this US patent. It turned out that the emulsion separates (dephazes) within an hour. The phenomenon is further accentuated at low temperatures below 5 ° C. We hardly dare imagine, what could happen in vehicle tanks containing this emulsion and placed in real winter conditions of use.
- N ° 101: 57 568 z targets an emulsified fuel comprising hydrocarbons constituted by derivatives of extremely viscous and heavy petroleum, water, ethanol and an emulsifier consisting of ethoxylated nonylphenol.
- This emulsified fuel is intended to be used in ovens, conventional oil burners. This fuel cannot meet the expected specifications for combustion performance, limitation of pollutants and low consumption. In addition, the physicochemical stability of this emulsion is not good.
- emulsified fuels which the present invention proposes to improve.
- emulsified fuels which can be fuels, comprise specific quantities of hydrocarbons and a set of additives in minor quantities including in particular an emulsifying system comprising sorbitan oleate, polyalkylene glycol and alkylphenol ethoxylate.
- the dispersed phase of these emulsified fuels consists of water present in an amount of 5 to 35% by weight while the additives are present in an amount of 0.1 to 1.5% by weight.
- concentration ranges for sorbitan oleate, polyalkylene glycol and alkylphenol ethoxylate are, respectively (in% by weight), from 0.20-0.26 / 0.20-0.25 / 0.20-0 , 27.
- the entire patent application reports the use of equal amounts of these three main additives: 1/1/1.
- One of the essential objectives of the present invention is to overcome this shortcoming by providing an emulsified fuel, in particular a fuel, formed by a stable water / hydrocarbon emulsion, which remains perfectly homogeneous over long periods of time, as well in storage tanks only in elements of the circuits constituting the combustion devices, in which said fuels may be used.
- Another essential objective of the present invention is to provide new improved emulsified fuels which provide good results in terms of reducing fuel consumption and reducing the emission of visible pollutants such as smoke and solid particles and pollutants. invisible gases such as CO, NO x and / or SO 2 , unburnt hydrocarbons and CO 2 .
- Another essential objective of the present invention is to provide new emulsified fuels which are of a low cost price, so as not to annihilate the gain obtained by the partial replacement of expensive hydrocarbons with water.
- Another objective of the present invention is to provide a process for the preparation of stable, non-polluting and economical emulsified fuels, which process must also be inexpensive and also easy to implement, without sophisticated operating protocol and device.
- the Applicant has continued its inventive effort and has developed new improved emulsified fuels, the originality of which is, on the one hand, to present an aqueous dispersed phase, consisting of small droplets provided with an interfacial film to counter the phenomenon of coalescence. It is also essential for the stability of the emulsion that the size distribution of the water droplets be as fine as possible, and on the other hand, to select a composition of the emulsifying system contributing to obtaining the stability specifications. , size and size distribution droplets of the aqueous phase in the diesel phase.
- the present invention relates to an improved emulsified fuel, consisting of an emulsion of water in at least one hydrocarbon, said fuel being characterized
- this emulsion comprises an emulsifying system comprising:
- radicals X are identical or different from each other and each correspond to: OH, R'COO- with R 1 representing an aliphatic hydrocarbon radical, saturated or unsaturated, linear or branched, optionally substituted by hydroxyls and having from 7 with 22 carbon atoms, R 1 preferably being a fatty acid residue deprived of a terminal carboxyl, this ester (T) having an HLB of between 1 and 9; ⁇ (H) at least one fatty acid ester of general formula: R2 - CO- ⁇ O ⁇ R 4 (
- R 2 represents an aliphatic hydrocarbon radical, saturated or unsaturated, linear or branched, optionally substituted by hydroxyl functions and having from 7 to 22 carbon atoms, R 2 preferably being a fatty acid residue deprived of a terminal carboxyl,
- R 3 being a linear or branched C 1 -C 10 alkylene, preferably C 2 -C 3 ,
- - n is an integer greater than or equal to 6, preferably between 6 and 30,
- ester (D) preferably having an HLB greater than or equal to 9;
- ⁇ (DI) at least one alkylphenolpolyalkoxylate of general formula:
- R 7 and R 8 correspond respectively to the same definitions as those given above for R 3 and R 4 of formula (II), this ester (HI) preferably having an HLB of between 10 and 15;
- composition suitable for the emulsifying system very clearly differ from the invention according to WO 93 18 117, which the present invention improves.
- the improved emulsified fuels which have these characteristics benefit from great storage stability over long periods of time. They do not phase-shift (phase separation), both in tanks and in the various elements constituting the supply circuits of devices suitable for serving as a seat for combusion, namely: internal combustion engines, burners ...
- the emulsion according to the invention remains perfectly homogeneous so that the risks of malfunction of the combustion devices are extremely limited.
- the stability of the emulsion is understood to mean that it is maintained in its initial physicochemical state of homogeneous emulsion.
- the fuels emulsified according to the invention provide, at the same time, very interesting and satisfactory performances, with regard to the reduction of polluting emissions and of consumption, and this for a reasonable cost price.
- the mean value in diameter of droplets of aqueous phase fixed at 3 ⁇ m, preferably 1 ⁇ m and more preferably still at 1 ⁇ m, and accompanied by a standard deviation of 1 ⁇ m maximum appeared to be one of the determining factors for guarantee the stability of the emulsion and in particular the limitation of coalescence and phase shift phenomena.
- a “monodisperse” particle size profile is therefore provided around 1 ⁇ m in practice (see curve in FIG. 5). This means that the droplet population is homogeneous in size, the latter also being low enough to contribute to stability.
- esters essentially consisting of oleates and, in smaller quantities, of palmitate, stearate and sorbitan linoleate. It can, for example, be so sesquioleate sorbitan, such as those marketed under the brand SPAN ® 83 and Arlacel ® 83 (ICI).
- esters (I) extend to all analogs and derivatives of fatty acid and sorbitan esters.
- the compound (Bf) is chosen from oleates and / or stearates and / or ricinoleates of polyalkyleneglycol and preferably of polyethylene glycol (PEG), preferably from those of which the PEG has a lower molecular weight or equal to 450, preferably around 300. It may, for example, be so PEG 300 monooleate of the type marketed under the trademark TILOL 163 ® (UNION DERIVAN SA), A EMULSOGEN ® (Hoechst ).
- nonylphenol ethoxylate it is eg nonylphenol ethoxylate. It can advantageously be replaced or combined with one or more other alkylphenol alkoxylates. It is thus interesting to retain the alkoxylates of alkylphenol (HT) in which the alkyl radical substituting the phenol contains approximately from 1 to 20 carbon atoms, preferably from 5 to 20. In addition, it is also preferable to select the alkoxylates (eg ethoxylate) of alkylphenol in which the alkoxyl chain preferably comprises from 8 to 20 and, even more preferably, from 8 to 15 groups of alkylene oxide (eg ethylene oxide) per molecule.
- alkylphenol eg ethoxylate
- polyethoxylated nonylphenol is thus preferred: C 9 H 19 -C 6 H 4 - (OCH 2 CH 2 ) m -OH, with 8 ⁇ m ⁇ 15. It indeed appeared essential in the context of the invention to use polyethoxylated nonylphenols, characterized not only by their hydrophilic nature, but also by cloud points, defined within the meaning of standard DIN 53917 with an aqueous solution at 1% by mass greater than 30 ° C.
- compounds (III) include octylphenol polyethoxylated particularly those marketed under the brand OCTAROX ® (SEPPIC) and OP n SINNOPAL ® (SIDOBRE-SINNOVA).
- the fuel or fuel according to the invention can be added using a number of products having various functionalities.
- additives which are soluble or miscible in water or else in hydrocarbons.
- These additives can therefore consist of one or more procetane products chosen, preferably, from peroxides and / or nitrates and their mixtures.
- the alkyl nitrates are examples of procetanes which can be incorporated into the emulsion via the hydrocarbon phase.
- Nitrate salts are the hydrophilic counterparts of alkyl nitrates. Their quality of salts allows them to be supported by the aqueous phase.
- the detergent function can also prove to be advantageous for the emulsions according to the invention. It is therefore advisable to consider the case where these include one or more detergent agents or additives.
- the nitrogen dioxide function (NOJ which can be provided by ammonia compounds (of the urea or ammonia type), is also valued in fuels and more particularly in fuels.
- NOJ which can be provided by ammonia compounds (of the urea or ammonia type)

- the present invention is perfectly in step with the current trend of using "green oil” as a partial substitute for fuel, in particular diesel.
- They can be, for example, rapeseed, soybean or sunflower oils, esterified or not, which can enter the fuel composition up to 5%, 30% or even 50% by mass for example.
- the present invention relates to a process for obtaining an emulsified fuel, characterized in that it essentially consists, simultaneously or not: - a - to use at least one hydrocarbon, water and an emulsifying system comprising:
- radicals X are identical or different from each other and each correspond to: OH, R ] COO- with R 1 representing an aliphatic hydrocarbon radical, saturated or unsaturated, linear or branched, optionally substituted by hydroxyls and having from 7 to 22 atoms carbon, R 1 preferably being a fatty acid residue deprived of a terminal carboxyl, this ester (I) having an HLB of 1 or 9; ⁇ (O) at least one fatty acid ester of general formula:

- R 7 and R 8 correspond respectively to the same definitions as those given above for R 3 and R 4 of formula (II), this ester (lu) preferably having an HLB of between 10 and
- the process according to the invention can therefore be summarized as an emulsion formation and a fractionation of this emulsion, so as to reduce the size of the droplets of aqueous dispersed phase until obtaining and maintaining a monodisperse particle size of 1 ⁇ m with a difference type less than 1 ⁇ m.
- the emulsification is largely based on the emulsifying system.
