Definitions
- the present invention relates more specifically to new fuel compositions constituted by emulsions of water in at least one hydrocarbon and generally in a mixture of hydrocarbons, such as for example that which composes diesel. It will therefore be a question in this presentation of water / hydrocarbon stabilized emulsions , comprising surfactants capable of allowing the emulsification and stabilization of such emulsions.
- the present invention also relates to a process for obtaining fuels (e.g. fuels) emulsified water / hydrocarbons associated with one or more several surfactants.
- fuels e.g. fuels
- emulsified water / hydrocarbons associated with one or more several surfactants.
- the present invention is part of the approach, for a long time in vogue, for developing fuel compositions, in particular fuels including substitutes for petroleum derivatives, for the sake of saving and limiting pollution.
- Water very quickly appeared as an interesting additive or partial substitute for petrol or diesel. Water is indeed an inexpensive and non-toxic liquid, which shown to be able to reduce fuel consumption, as well as emissions of visible or invisible pollutants.
- the second apprehensible approach consists in implementing ready-made mixtures of water and fuel, but that was not to mention the considerable problems of storage stability of such mixtures in fields of temperature varying from - 20 ° C to - 70 ° C, and stability under conditions use of the emulsion in a tank.
- phase separation phase shift / demixing
- an emulsified fuel comprising a number of additives including an emulsifying system formed of sorbitan sesquioleate, monooleate of sorbitan and polyoxyethylene ( 6 EO) of dodecyl alcohol.
- the total concentration of all the additives is approximately 2.1%.
- the other additives that can be used can be: a mono- ⁇ -olefin (decene-1), methoxymethanol, toluene, an 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 can be fuels, include 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.
- 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 low-cost emulsified fuels so that not to annihilate the gain obtained by the partial replacement of expensive hydrocarbons with water.
- Another object of the present invention is to provide a method of preparation of stable, non-polluting and economical emulsified fuels, which process should also be inexpensive and also easy to implement work, without sophisticated operating protocol and device.
- 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.
- This absence of phase shift (phase separation) and coalescence, whether by gravity or by any other means of separation (filtration, centrifugal effect, etc.) constitutes major technical progress, which makes it possible to concretely envisage industrial applications and serious business.
- the stability of the emulsion is understood to mean maintenance of the latter in its initial physicochemical state of homogeneous emulsion (no phase shift, no coalescence of the dispersed phase droplets), during a storage for at least 3 months at room temperature.
- the fuels emulsified according to the invention provide at the same time quite interesting and satisfactory performances, as far as concerns the reduction of polluting emissions and consumption, and this for a reasonable cost price.
- the mean value in diameter of droplets of aqueous phase fixed at 3 ⁇ m, preferably 2 ⁇ 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.
- HLB Hydrophilic-Lipophilic-Balance
- This is a well-known parameter for characterizing emulsifiers.
- the qualitative and quantitative composition of the emulsifying system is also an essential element of the invention, which contributes to the results obtained especially with regard to stability.
- the emulsion comprises at least 5% by weight of water and the emulsifier system concentration relative to the total mass of the fuel is less than or equal to 3% by weight, preferably 2% by weight.
- the fatty acid ester of sorbitan ( I ) preferably consists essentially of one or more C 18 sorbitan oleates, optionally combined with one or more esters of C 18 fatty acid (linoleic, stearic) and in C 16 (palmitic).
- the ester ( I ) is not limited to monoesters of fatty acids and of sorbitan but extends to di and / or tri-esters and their mixtures.
- one of the selection criteria for this ester ( I ) is advantageously belonging to the range of HLB between 1 and 9, which gives it a marked lipophilic tendency.
- the HLB more particularly preferred for the ester ( I ) is between 2.5 and 5.5.
- esters essentially consisting of oleates and, in smaller quantities, of palmitate, stearate and sorbitan linoleate. It may, for example, thus be sorbitan sesquioleate, of the type of those sold under the brand SPAN 83® or ARLACEL 83® (HERE).
- sorbitan esters ( I ) As other examples of sorbitan esters ( I ), mention may be made of sorbitan laurates, of the type sold under the brand SPAN 20® or ARLACEL 20® (ICI), ALKAMULS SML (RHONE POULENC), sorbitan stearates of the type sold under the ARLACEL 60® brand (HERE) or ALKAMULS SMS (RHONE POULENC), without this list being exhaustive. It goes without saying that, within the meaning of the present invention, the esters ( I ) extend to all analogs and derivatives of fatty acid and sorbitan esters.
- compound ( II ) is chosen from oleates and / or stearates and / or ricinoleates of polyalkyleneglycol and preferably of polyethylene glycol (PEG), preferably from those whose PEG has a molecular weight less than or equal to 450, preferably of the order of 300. It may, for example, thus be a PEG 300 monooleate of the type of those sold under the brand TILOL 163® (UNION DERIVAN SA), EMULSOGEN A® (HOECHST).
- PEG 300 monooleate of the type of those sold under the brand TILOL 163® (UNION DERIVAN SA), EMULSOGEN A® (HOECHST).
- the alkylphenol ( III ) alkoxylate is preferably chosen from nonylphenols and / or polyethoxylated octylphenols, polyethoxylated nonylphenols being particularly preferred.
- alkylphenol ethoxylate In practice, 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 ( III ) 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, more preferably still, from 8 to 15 groups of alkylene oxide (eg ethylene oxide) per molecule.
- alkylene oxide eg ethylene oxide
- polyethoxylated nonylphenol C 9 H 19 -C 6 H 4 - (OCH 2 CH 2 ) m -OH, with 8 ⁇ m ⁇ 15. It 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. A combination of these characteristics has indeed made it possible to obtain not only efficient emulsifying systems for the preparation of a water-fuel emulsion within the meaning of the invention, but, moreover, to obtain quite remarkable temperature resistance properties and capable of making this emulsion stable in a wide range of temperature.
- compounds (III) include octylphenol polyethoxylated particularly those marketed under the brand OCTAROX® (SEPPIC) and OP n SINNOPAL ® (SIDOBRE-SINNOVA).
- the compound ( III ) of the emulsifying system is a mixture of polyethoxylated nonylphenols, preferably two polyethoxylated nonylphenols having 9 and 12 ethylene oxide residues respectively
- the fuels more specifically targeted by the present invention are those in which the hydrocarbon or the mixture of hydrocarbons entering into their constitution is (are) chosen from the following group of products: diesel fuels , gasolines, kerosene, fuel oils, synthetic fuels, vegetable or animal oils, esterified or not, and their mixtures. Even more preferably, the present invention relates to a particular group of fuels that are fuels (gas oils, gasolines, kerosene, synthetic fuels, vegetable or animal oils whether or not esterified) used as fuels in internal combustion engines or heat engines.
- the fuel or fuel according to the invention can be added using a number of products having various functionalities.
- one of the main advantages of the hydrocarbon / water emulsions according to the present invention is to offer two different types of support for the additives, namely: a lipophilic support constituted by the continuous hydrocarbon phase and a hydrophilic support constituted by the aqueous phase.
- only the oil-soluble compounds could be incorporated easily into fuels.
- This constraint is now eliminated thanks to the present invention, all the more since the solubility in water is a property offered to a number of products far greater than that of products soluble in fuels within the meaning of the invention.
- additives soluble or miscible in water or even in hydrocarbons may therefore consist of one or more selected procetane products, preferably among the peroxides and / or nitrates and their mixtures.
- Nitrates are examples of procetanes which can be incorporated into the emulsion via the hydrocarbon phase.
- the nitrate salts are the hydrophilic pendants of alkyl nitrates. Their quality of salts allows them to be supported by the aqueous phase.
- the anti-soot function is another function which it is possible to provide in the emulsified fuels of the invention.
- the promoters of such a function are advantageously additives consisting of at least one metallic catalyst or alkaline earth, capable of promoting the post-combustion reaction of soot, said catalyst preferably based on magnesium, calcium, barium, cerium, copper, iron or their mixtures.
- These catalytic soot destruction promoters are all the easier to introduce since they are generally compounds whose salts are soluble in water, which makes them compatible with the aqueous phase of emulsions according to the invention. The same is not true for conventional fuels of the prior art exclusively consisting of hydrophobic hydrocarbons.
- biocidal or even bactericidal properties to emulsified fuels.
- biocide preferably a bactericide.
- the detergent function can also be useful for 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 (NO x ) function which can be provided by ammonia compounds (of the urea or ammonia type), is also valued in fuels and more particularly in fuels.
- the present invention is perfectly in step with the current trend of using "green oil” as a partial substitute for fuel, in particular diesel.
- "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 process according to the invention can therefore be summarized as a training of emulsion and a fractionation of this emulsion, so as to reduce the size of the droplets of dispersed aqueous phase until obtaining and maintaining a monodisperse particle size of 1 ⁇ m with a standard deviation of less than 1 ⁇ m.
- the method according to the invention can be one of those usable for prepare the improved emulsified fuel (e.g. fuel) described above. he It follows that by extension, the characteristics and observations given in the description above about the products used in the emulsion, can be fully transposed in this part of the presentation on the process.
- the fractionation of the emulsion is a mechanical or thermomechanical treatment aimed at breaking the cohesive force of the droplets, so as to promote their subdivision.
- the fractionation means preferably used during step (c) are of the static mixer, centrifugal or other pump type, colloidal mill or other, rotor mixer, ultrasonic mixer and other method of fragmenting a liquid in another immiscible liquid.
- static mixers can be used as fractionation means. These static mixers are bodies through which the emulsion is passed at high speed and in which it undergoes sudden changes in direction and / or in diameter of the pipes which make up the interior of the mixers. This leads to a pressure drop, which is a factor in obtaining a correct emulsion in finesse and stability.
- a rotor mixer of the type of those marketed under the ULTRA-TURRAX® brand a high homogenizer pressure of the type of those sold by APV-BAKER or any known process for those skilled in the art and allowing an easy extrapolation of scale.
- the steps b and c of mixing / fractionation are, for example, sequential, that is to say that the procedure consists of first mixing the hydrocarbon (s) and the emulsifying system and any additives, the premix being in a second time mixed and emulsified with water.
- Steps - a - to c - of the method according to the invention take place at ambient temperature, which is also that of the fluids and raw materials used.
- the emulsified fuel conforms to the invention and / or obtained by the process according to the invention, is dedicated to multiple industrial and commercial applications.

- the pressure of the fluid at the outlet of pump 8 is 5 MPa.
- the 30 kg of water are introduced in approximately 1 min.
- the system works in a loop to ensure fractionation for 30 min.
- 200 kg of emulsion corresponding to the characteristics of the invention are thus obtained.
- This emulsion has a whitish color and a kinematic viscosity of 6.2 mm 2 / s at 20 ° C.
- 200 kg of emulsion are also prepared with 164 kg of diesel, 4 kg of emulsifying system, 2 kg of additives consisting of magnesium oxide and toluene and 30 kg of water.
- the proportions of SORBITHOM® S06: TILOL 163®: NONILFENOL® 9 M OXIETHIL® are 1: 1: 1 and not 3: 2: 1 as provided in paragraph II.1. above.
- This emulsifying system has an HLB of 8.7.

- the timing of the comparative bus is explained by the lack of stability of the emulsion II.2. , which underwent a phase shift by gravity settling during the 48-hour outage. It follows that during the withdrawal of fuel from the tank base, large amounts of phase-shifted water were brought by the injection pump to the combustion chamber. These excessively high water contents cause the engine to stall irreparably.
- a series of tests is carried out on the RVI R312 vehicles mentioned above by subjecting them to an operating cycle as shown in FIG. 4 and comprising a phase R of idling, a phase A of acceleration, a phase P of full speed (plateau) and a deceleration phase D.
