Definitions
- the invention relates to a process for the production of fatty acid esters from oil seeds such as sunflower, soybean, rapeseed, crambe, flax, castor, sesame, cotton, coconut, palm kernel, safflower, etc., this process making it possible to totally transesterify the glycerides of the seeds or, on the contrary, transestify only a fraction thereof in order to obtain directly derived formulations (mixtures of esters and oils and possibly other components).
- oil seeds that is to say rich in glycerides
- the proteo-oil seeds that is to say rich in glycerides and proteins
- seeds not specially known to be oilseeds but containing glycerides seeds not specially known to be oilseeds but containing glycerides.
- seeds is meant any type of organ of a plant in which lipids are stored (seeds, beans, germs, seeds, almonds ).
- the invention extends to a device specially designed for implementing the method.
- the traditional methods of manufacturing fatty acid esters from oil seeds comprise two very distinct stages: first an extraction of oil from the seeds, then a chemical treatment of this oil.
- the oil extraction is generally carried out in presses which ensure the grinding of the seeds and an extraction of the liquid phase; additional solvent extraction (hexane) is often performed.
- additional solvent extraction hexane
- the chemical treatment of the extracted oil then consists in transesterifying the glycerides contained in it by the reaction: glyceride + alcohol -> ester + glycerol, in the presence of an acid or basic catalyst.
- transesterification reaction by acid catalysis has a very slow kinetics and the reagents must be brought into hot contact and generally under pressure for long periods (several hours).
- transesterification by basic catalysis can be carried out more quickly but requires a refined oil, reagents and anhydrous operating conditions.
- the present invention proposes to provide a new process for the production of fatty acid esters from oil seeds. It is aimed at a single-step process, benefiting from an adjustable yield (which can be very high if desired) and free from some of the faults of this type of process.
- An objective of the invention is to make it possible to obtain a total transesterification of the glycerides or, on the contrary, simply a partial transesterification in order to conserve the glycerides in the final composition obtained (for certain applications requiring specific formulations).
- An object of the invention is in particular to provide a method leading to significantly shorter treatment times compared to those of existing or proposed methods.
- Another objective is to authorize the use of an acid catalyst as well as a basic catalyst (the preferred mode of implementation of the process of the invention providing for the use of a basic catalyst).
- Another objective is to reduce the quantities of alcohol used compared to those necessary in the in situ and batch process.
- Another objective is to extend the scope of transesterification to all types of alcohols, and in particular to long-chain alcohols, substituted or not, to hindered alcohols, to polyols.
- Another object of the invention is to provide a continuous process having all the advantages of continuous processes and not requiring separate operations to separate the liquid phase from the solid materials.
- Another objective is to provide a process which preserves the other constituents of the seed and allows their subsequent development, in particular by fractionation.
- the process targeted by the invention for manufacturing fatty acid esters from oil seeds is of the type in which the seeds are directly subjected to an at least partial chemical transformation of transesterification in the presence of a transesterification reagent consisting of a alcohol and a transesterification catalyst; according to the present invention, this process is characterized in that the chemical transesterification transformation is carried out continuously in a twin-screw device so as to simultaneously subject the seeds to a mechanical shearing treatment, the alcohol and the catalyst being injected into the twin-screw device in the vicinity of the seed inlet with an adjustment of the amount of alcohol relative to the seeds such that the proportion of alcohol is substantially between 0.3P and 3P, where P is the proportion of alcohol corresponding to the stoichiometry of the transesterification reaction: glyceride + alcohol -> ester + glycerol.
- Twin-screw devices are well known in their design and used to subject solid materials to mechanical treatments, for example defibering cellulosic materials in the paper industry. To the knowledge of the inventors, they have not been applied to combine a mechanical shearing treatment of solid materials and a chemical transformation of the constituents of these materials. In the process of the invention, the two chemical and mechanical treatments are carried out simultaneously and continuously in such a twin-screw device, and it is unexpectedly observed that the transesterification reaction of the glycerides contained in the seeds can be produced in a manner quantitative, the liquid phase collected at the outlet containing no more glycerides (or practically more glycerides). Preferably, the proportion of alcohol will be greater than or equal to P for obtaining a total transesterification.
- the experiments made it possible to highlight that the proportion of alcohol and the proportion of catalyst used interact to lead to a total transesterification or to a more or less extensive partial transesterification.
- the process of the invention is carried out with a proportion of alcohol greater than the stoichiometry, in particular greater than or equal to P, when total transesterification is sought; in addition, the quantity of catalyst used will preferably be adjusted within the high range of the range of the abovementioned proportions. On the contrary, to obtain a partial transesterification, the proportion of alcohol and / or that of catalyst will be lowered; the proportion of catalyst is preponderant to lead to a given conversion rate.
- the basic catalyst can be introduced in solid form into the twin-screw device, which considerably simplifies its handling on an industrial level, facilitates its dosage and limits the quantities of water introduced. It should be noted that this catalyst can itself be introduced into the device, but that it is also possible to introduce reagents capable of producing this catalyst in situ.
- the basic catalyst (or the reagents capable of producing it) is advantageously injected into the twin-screw device so that the proportion by weight of catalyst / seed is substantially between 1% and 10%. This value range makes it possible both to obtain a satisfactory catalysis effect and to have solid matter impregnated by the base at the outlet of the twin-screw device under conditions making it possible to carry out the fractionation of the secondary constituents of said materials and their subsequent recovery.
- the basic catalyst can preferably be injected into an area of the twin-screw device located upstream of the area where the alcohol is injected. This limits the solubilization of lipids by alcohol which could make the heterogeneous mixing of the various elements more difficult.
- the process of the invention leads to mass yields which can approach 45% in the event of total transesterification (the yield being defined as the ratio of the mass of esters actually obtained to the mass of theoretical esters obtained by a total stoichiometric reaction ).
- the process of the invention is a continuous process which has on an industrial level the well-known advantages of this type of process compared to the previous processes implemented "in batch" (economy of handling, ease of automation, greater productivity ).
- the liquid phase is separated from the solid materials directly by the twin-screw device, the withdrawal of this phase being ensured through a filter in a terminal zone of the device.
- This regulation can be obtained by using a twin-screw device contained in a double-walled tubular enclosure and by circulating in the double wall of the enclosure a thermal regulation liquid at a temperature substantially between 50 ° C. and the temperature of reflux of alcohol used.
- an increase in temperature increases the kinetics of the transesterification reaction and the twin-screw device is advantageously heated to regulate the temperature of the reactive medium to a value substantially between 20 ° C. and a moderate temperature (80 ° to 120 ° C).
- the method of the invention thus makes it possible to extend the types of fatty acid esters capable of being manufactured by its implementation; depending on the ester sought, the alcohol or a mixture of alcohol from the following group may in particular be chosen: isopropanol, butanol, hexanol, octanol, decanol, stearic alcohol, oleic alcohol, palmitic alcohol, hexadecanol, 2-ethylhexanol, propane -1, 2-d ⁇ ol, propane-1, 3-diol, butane-1, 2-diol, butane-1, 3-d ⁇ ol, butane-1, 4-diol, hexane-1, 6-diol, octane- 1 , 8-d ⁇ ol, glycerol, xylitol,
- the twin-screw device used in the process of the invention comprises, from upstream to downstream, an area provided with shear mixers to the exclusion of axial compression mixers, an area for withdrawing the liquid phase through a filter and a terminal zone provided with means for axial compression of the solid materials before their exit. This avoids carrying out an oil extraction in the zone where the transesterification reaction takes place, this reaction occurring on the glycerides m situ.
- the invention extends to a twin-screw device specially designed for implementing the method defined above.
- This device is of the type comprising a tubular enclosure, means of thermal regulation of said enclosure, twin-screw modules with two co-penetrating screws, mixing modules composed of shear discs, an inlet for raw materials at the end upstream, and a solids outlet at the downstream end; in accordance with the invention, this device is characterized in that: - means for injecting a reagent and a transesterification catalyst are arranged in the vicinity of the inlet of raw materials, means for withdrawing liquid provided with a filter are arranged upstream of the solids outlet,
- twin-screw modules and kneading modules which are located upstream of the withdrawal means are modules of a type suitable for subjecting the materials to shear stresses, excluding significant axial compression,
- At least one twin-screw module or kneading module, mounted with inverted pitch, is arranged downstream of the withdrawal means to achieve axial compression of the solid materials at this level.
- FIG. 1 is a cross section through a plane AA '.
- the device was produced from modules sold by the company "CLEXTRAL” (registered trademark) under the general reference "BC21".
- Each module includes a double-walled tubular enclosure 1 and 2 which allows thermal regulation of the core of the enclosure where the active members are housed.
- Some modules are of the type comprising two identical co-penetrating screws, others of the type comprising shear mixers composed of bilobe discs.
- the various modules are rotated in synchronism by an electric motor 3 making it possible to obtain a speed of rotation of its output shaft which can reach 600 rpm.
- the system essentially comprises the following functional sections (upstream to downstream):
- impregnation section Z- ⁇ comprising a hopper 4 for supplying oil seeds, an inlet 5 for the introduction of the catalyst in the form of solid powder, a conduit 6 provided with a pump for the injection of alcohol and four direct screw bis-modules such as 7, a section called transesterification section Z2, combining two kneading modules such as 8 located on either side of a twin-screw module with direct pitch 9, a section known as drawing off Z3, comprising a filter 10 for drawing off the liquid phase and three direct pitch twin screw modules such as 11, followed by an inverted pitch twin screw module 12,
- a terminal section Z4 comprising a direct screw twin-screw module 13 and an outlet 14 for solid materials.
- the impregnation section Z- combines four direct-screw twin screw modules 7, with decreasing steps from the first to the fourth: module of type T2F 50 x 100 (trapezoidal double thread screw, length 100 mm, positive pitch 50 mm), module of type C2F 33 x 100 (double threaded conjugate screw, length 100 mm, positive pitch 33 mm), module type C2F 25 x 50 (double threaded conjugated screw, length 50 mm, positive pitch 25 mm) and C2F module 16 x 50 (double threaded conjugated screw , length 50 mm, positive pitch 16 mm).
- the catalyst inlet 5 is located downstream of the conduit 6 for injecting the alcohol.
- the twin screws with decreasing pitch carry out the conveying, mixing and mixing of solid and liquid materials.
- the direct screw twin screw 9 in particular of the type C2F 16 x 50 ensures the conveying of the materials, while the two kneading modules 8 subject the materials to a shear (in the absence of axial compression ).
- These kneading modules are respectively of the MAL2 type 10 x 100 (45) (ten two-lobe discs mounted with a 45 ° pitch, total length 100 mm) and of the MAL2 type 10 x 50 (90) (ten two-lobe discs mounted with a pitch 90 °, total length 50 mm).
- transesterification takes place in situ, without significant oil extraction (due to the absence of significant axial compression).
- the three modules 11 of bis-step screws direct from the withdrawal section Z3 are respectively of the type C2F33 x 50, C2F25 x 25, C2F16 x 25. They are followed by a module 12 of twin-screw with reverse pitch of the C2C type 25 x 25 (conjugate screw with reverse pitch of 25 mm); this screw performs axial compression downstream of the outlet filter 10, allowing good extraction of the liquid phase.
