Definitions
- the present invention relates to a cetane improving component without degradation of the cold behavior and without degradation of the oxidation stability of diesel fuels, as well as diesel fuels comprising this component. It relates more particularly to the incorporation of components derived from products of plant or animal origin in diesel fuels.
- Fuels containing vegetable oil derivatives have a reduced emission rate and increased biodegradability, but they usually exhibit a very high sensitivity to oxidation and show very poor cold properties.
- the sale of fuels including these derivatives has increased significantly in recent years because obtaining these derivatives becomes more competitive with traditional fuels derived from petroleum. Especially the production of such fuels makes it possible to envisage the future in a more favorable way whereas the stocks of oil diminish.
- the poor cold properties of these components and their high sensitivity to oxidation have for a long time been limiting factors for their use at high concentrations in Diesel fuels their physicochemical characteristics likely to jeopardize the proper functioning of the engines of the market.
- These vegetable oil derivatives are often products of the transesterification of triglycerides of vegetable or animal oils. They have a high cetane number corresponding to a good behavior of the burning fuel. For these derivatives, a cetane number of at least 47 is required according to United States standards (ASTM D 6751) and an index of 51 in some European countries (eg Germany). Since cetane numbers are correlated with low nitrogen oxide emissions, the addition of these products may be of great importance for the production of diesel fuels with added vegetable and animal oil products.
- EP 1484385 has been described a biofuel containing 100% by weight of a mixture of palm oil esters, this mixture having a low pour point, particularly suitable for cold countries without adding additives .
- This biofuel is produced by esterification of a mixture of Cl 8 (stearic), Cl 8: 1 (oleic) and Cl 8: 2 (linoleic) fatty acids with methanol or ethanol, followed by the fractional distillation of Methyl and ethyl esters, finally crystallization.
- the biofuel is prepared by mixing these fractions from the distillation of palm oil. It is used as fuel, in an environmental concept, as a substitute for diesel fuels, obtained from palm oil and conventional mixtures of palm oil esters.
- the olefinic fatty acid esters comprising more than 16 carbon atoms and in particular the methyl esters are known for their good cold properties but also for their high sensitivity to oxidation.
- saturated fatty acid esters of up to 18 carbon atoms are known to tend to deteriorate the flow properties of biodiesels.
- the present invention relates to a cetane improving component and oxidation stabilizer for diesel fuels, comprising at least one stearic ester chosen from esters of linear or branched monohydric alcohols containing 1 to 6 carbon atoms a) in the pure state added to a mixture of at least one crude or partially hydrogenated vegetable or animal oil ester b) or included in a mixture of esters of one or more vegetable and / or animal oils in raw or partially hydrogenated form , the saturated and unsaturated ester mixtures being such that the mass ratio of the stearic ester (s) content (s) to the sum total of the unsaturated ester content present in the vegetable or animal oil esters varies from 1 at 12% by weight, and the unsaturated fatty acid esters being esters of mono or polyunsaturated acids containing at least 18 carbon atoms, and monoalcohols ,.
- stearic ester chosen from esters of linear or branched monohydric alcohols containing 1 to 6 carbon atoms
- stearic esters of vegetable or animal oil will cover the esters resulting from the esterification of vegetable and animal oils, whether they are totally or partially hydrogenated, whether they are extracted or not. It would not be departing from the scope of the present invention if the pure stearic acid ester was used, optionally in admixture with at least one unsaturated linear acid ester of more than 16 carbon atoms.
- the component is used in a concentration such that the stearic esters contribute to improving the cetane number without deteriorating the cold behavior of the fuel and improving the oxidation stability of the hydrocarbons.
- the ratio by weight of esters generally ranges from 1 to 12%, and preferably is between 5 and 9 , 6% and more preferably between 7 and 9.0%.
- the stearic ester is advantageously chosen from esters of linear or branched monohydric alcohols containing 1 to 6 carbon atoms.
- the methyl or ethyl esters, or the n-propanol, isopropanol, n-butanol or tert-butanol esters, and more particularly the methyl or ethyl stearic acid esters are preferred.
- the stearic ester may be of natural or synthetic origin. Stearic esters are present in all esters of vegetable or animal oils. Particularly, it may be derived from the partial or total hydrogenation of esters of vegetable or animal oils with a high content of unsaturated C 8 fatty acid esters. preferably linear, such as esters of oleic, linoleic and linolenic acids.
- the stearic ester may be introduced into a fuel as part of an ester of a vegetable or animal oil or as part resulting from the mixture of several vegetable and / or animal oil esters.
- each ester contained by type of esterified acid was refined and / or separated and if these esters of acids in the proportions required for carrying out the invention in the fuel.
- esters of acids containing 18 or more carbon atoms are preferred in admixture with the stearic esters, because of their good influence on the cold properties of diesel fuels: they are effective in tempering the negative effect of stearic esters on these properties.
- Preferred unsaturated esters are the acid esters oleic, linoleic or linolenic. These unsaturated fatty acid esters may be of natural or synthetic origin. They are present in esters of vegetable or animal oils at varying concentrations depending on the variety of the esterified oil.
- the ester of stearic acid present in these mixtures makes it possible to limit the well-known oxidation of these unsaturated esters and to stabilize this effect.
- the increase in cetane and the improvement of the cold operability of the fuels are optimal when there is an appropriate combination of stearic ester with unsaturated acid esters containing at least 18, preferably linear, carbon atoms.
- vegetable or animal oils include triglycerides of monocarboxylic fatty acids.
- the number and nature of acidic residues in glyceride composition define the variety of each of these oils.
- the ester mixtures may optionally come from a mixture of esters of vegetable or animal oils such as, in particular, rapeseed oil esters (for example methyl or ethyl rape esters), palm oil esters (ester eg methyl or ethyl palm oil), esters of pine oil (methyl or ethyl ester of pine for example), esters of soybean oil (methyl or ethyl ester of soya for example), oil esters sunflower (methyl and / or sunflower ethyl esters, for example), esters of corn oil (methyl or ethyl ester of maize for example), esters of safflower oil (methyl or ethyl ester of safflower, for example), esters of cottonseed oil (eg methyl and ethy
- Esterification of triglycerides of fatty acid present in these oils can be implemented according to known methods. In particular, it may be carried out by alcoholysis, using the alcohols mentioned above as described by J.-C. Guibet et al., Fuels and Engines, Ed. Technip Paris or according to the European patent application EP 860,494.
- the present invention it is possible to use a mixture of several vegetable and / or animal oil esters to introduce the necessary quantities of stearic esters and unsaturated fatty acid esters of at least 18 carbon atoms.
- the mixture may advantageously comprise two, three or more esters of different oils. It is understood that the suitable mixtures are limited to those which make it possible to reach a value of the mass ratio [ester (s) stearic / the sum of the unsaturated esters of Cl 8 and higher] of between 1 and 12%, preferably ranging from 5 to 9.6% and even more favorably from 7 to 9%.
- the present invention also relates to the use of a cetane improving component and oxidation stabilizer for diesel fuels, as defined above, for the preparation of an improved cetane diesel fuel without deterioration of the cold properties and the oxidation stability of said fuel, from a mixture of vegetable and / or animal oil esters.
- Another object of the present invention also relates to a diesel fuel comprising:
- At least one component comprising at least one saturated ester of more than 16 carbon atoms, preferably comprising at least one stearic ester chosen from esters of linear or branched monohydric alcohols containing 1 to 6 carbon atoms:
- esters of one or more vegetable and / or animal oils in raw or partially hydrogenated form the saturated and unsaturated ester mixtures being such that the mass ratio of the ester content (s) stearic (s) on the sum total of the unsaturated esters content present in the esters of vegetable or animal oils varies from 1 to 12%, the unsaturated fatty acid esters being esters of mono or polyunsaturated acids containing at least 18 carbon atoms, and monoalcohols, and the ester content of stearic acid in said fuel being at least 0.5% by weight.
- hydrocarbons are derived from petroleum distillation cups, but also from biomass, essentially paraffinic hydrocarbon mixtures resulting from the conversion of the gas into hydrocarbons or any other process making it possible to obtain all or part of such mixtures or a mixture. of these various sources of hydrocarbons.
- the stearic ester is introduced in pure form or in any other form into the fuel, its concentration shall be maintained at or below 2.4% by mass.
- the stearic ester content in the fuel can vary between 0.5 and 2.4%, preferably between 0.5 and 1.2% and the weight ratio of stearic ester / sum of unsaturated acid esters, present in the fuel, can vary between 1 and 12%, preferably between 5 and 9.6% by weight and more particularly between 7 and 9% by weight.
- esters of several vegetable and / or animal oils are advantageously used to achieve the optimum composition of stearic esters / unsaturated esters comprising at least 18 carbon atoms. It is understood that the optimal mixtures are limited to those which make it possible, depending on the amount of stearic ester present, to have a final stearic ester content always less than or equal to 2.4% by weight, at a ratio value. in mass [stearic ester / sum of ester (s) of unsaturated acids] of between 1 and 12% and preferably between 5 and 9.6% and more particularly between 7 and 9%.
- the stearic ester content will advantageously be between 0.5 and 1.2% by weight in the fuel and the weight ratio [stearic ester / sum of the ester (s) of the unsaturated acids] will be between 7 and 9%.
- the stearic esters When the stearic esters are in the presence of high concentrations of at least one second C16 saturated acid ester, the palmitic ester, this must be taken into account. Indeed, the effects of these esters are similar to those of the stearic esters, in particular on the cold behavior of the fuel.
- the Applicant has thus found that the sum of the stearic esters and palmitic esters, that is to say the sum of the saturated esters of Cl 6 and Cl 8 acids, was a limiting factor for vegetable oil ester mixtures in diesel fuels. Thus, the amount of C16 and C18 saturated esters can not exceed 10% by weight of the fuel.
- the concentration of the combination in the fuel can be set beyond 10% and even 20%, to increase the cetane while maintaining the stability of the fuels with the oxidation with good flow properties and cold filterability. It allows in particular that the filterability additives, in particular the EVA (polyethylenevinylacetates) have a good efficiency on the filterability temperature of the resulting fuel.
- EVA polyethylenevinylacetates
- the said fuel may also include other additives intended to improve the cold properties, the flow or the filterability, but also anti-foam, lubricity, conductivity, anticorrosion, detergency and demulsification additives that any person skilled in the art would not forget to introduce, as well as bactericides.
- the fuel may be low in sulfur, preferably less than 500 ppm sulfur, preferably less than 100 ppm.
- the present example aims to demonstrate the feasibility of introducing mixtures of two vegetable oil esters of different types chosen from rapeseed (EMC), soy (EMS) and palm (EMP) methyl esters and the influence of these mixtures introduced at different concentrations in a type of diesel fuel EN590 (GO1) and a heating oil (FOD1) whose characteristics are given in Table I below.
- EMC rapeseed
- EMS soy
- EMP palm
- Table II gathers the respective amounts of saturated acid esters of Cl 6 and Cl 8 and unsaturated fatty acids of at least 18 carbon atoms in the various esters envisaged.
- the mixtures according to the invention were made by varying the respective concentrations of rapeseed methyl ester and methyl ester of palm and varying the concentration of the mixture in each of the two hydrocarbons. Each test will be referenced by X; for the GO and Y; for FOD as described in Table III below.
- Table III shows that it is possible to introduce more than 20% of a mixture of vegetable oil esters into hydrocarbons such as gas oil and heating oil. insofar as the concentration of stearic ester (C 18 sat) is always less than 1.2% by weight for a minimum deterioration of the filterability limit temperature (TLF) measured by applying the EN 16 standard by increasing the temperature of 6 0 C.
- TLF filterability limit temperature
- the TLF reactivity is not degraded and the gain remains at a level greater than 6 ° C relative to the non-additive mixture.
- it is possible to correct this deterioration by adding a TLF additive based on EVA (polyethylenevinylacetate).
- EVA has an action only when the mass ratio of saturated [Cl 8 / sum of unsaturated Cl 8] is maintained less than or equal to 9% by mass, and especially a content of (C 16 + Cl 8 sat) corresponding to the sum of the stearic and palmitic esters, always less than 10% by weight in the said fuel.
- the oxidation stability characteristics of the mixtures are measured by the iodine number (IN) determined by the EN14214 standard.
- the description of these compositions is the following (% by weight):
- Examples A to D according to the invention fulfill the criteria of the ratio of stearic ester / unsaturated esters and oxidation stability, while also leading to compositions having good cold properties and an iodine number of less than 110.
