Definitions
- the invention relates to a process for the production of biofuels from triglycerides leading to a mixture of fatty acid monoesters and soluble glycerol derivatives, namely ethers and / or glycerol acetals.
- biofuels means fuels or constituents for fuels consisting of (or comprising) one or more products, in particular oxygenated products, having a natural origin.
- Biodiesel denotes more particularly a fuel or a fuel constituent for diesel engines consisting of (or comprising) at least one alkyl ester of fatty acid of natural origin, such as a mixture of methyl esters of oil. vegetable (rapeseed, sunflower, etc.).
- the foreseeable massive development of Biodiesel will lead to the production of a quantity of glycerol equivalent to approximately 10% by mass of the Biodiesel produced. For example, an increase in Biodiesel production of
- glycerol is neutral, that it contains no salt or mineral or metallic compound and that its water content is very low.
- crude glycerol obtained from conventional Biodiesel manufacturing processes does not meet these requirements.
- conventional Biodiesel manufacturing processes use generally basic homogeneous catalysts, for example soda, potash, sodium or potassium alcoholates, such as sodium methylate. These catalysts, after reaction of transesterification of the triglyceride into methyl ester by methanol for example, are found both in the ester, generally in the form of metallic soaps / carboxylates, for example of sodium, and also in the co-produced glycerol in the form of alcoholate, for example sodium or potassium.
- the glycerol obtained contains catalyst or most often a compound derived from the catalyst, for example sodium or potassium glycerate.
- the glycerol also contains water in proportions which can range from a few% to for example 35% depending on the process used.
- the crude glycerol thus obtained from conventional processes for the production of Biodiesel cannot be directly used to be chemically modified by an olefin such as isobutene to lead to mixtures of ethers, since this reaction requires a neutral glycerol therefore free alkoxide.
- the presence of water is unfavorable for the proper conduct of this reaction.
- the neutral glycerol containing catalyst or compounds derived from the catalyst is neutralized by an acid such as for example hydrochloric acid or sulfuric acid
- the neutral glycerol will contain salts such as for example sodium or potassium chlorides or sodium or potassium sulfates.
- a treatment to eliminate them must be inserted between this step and the final step of incorporating the glycerol ether derivative or the acetal glycerol derivative in the fuel.
- This treatment generally consists of a distillation of the prepared product, which is costly in investment and in energy.
- the invention provides a process for manufacturing a composition which can be used as fuel or as fuel constituent from '' at least one triglyceride formed between at least one fatty acid and glycerol, said process comprising: - at least one transesterification step in which said triglyceride is reacted by heterogeneous catalysis with at least one primary monoalcohol chosen from methanol and ethanol, to give, on the one hand, at least one methyl and / or ethyl ester of the fatty acid (s) of the starting triglyceride (s) and, on the other hand, of glycerol, these products being free from by-products; and - an etherification step in which the glycerol is reacted with at least one olefinic hydrocarbon of 4 to 12 carbon atoms; and / or - an acetalization step in which the glycerol is reacted with at least one compound chosen from aldehydes, ketones and ace

- the catalyst can be in the form of extrudates with a diameter of between 0.5 and 3 mm and is packaged in a tube making it possible to operate in a fixed bed.

- VVH oil volume / catalyst volume / hour
- alcohol / oil weight ratio varying from 2/1 to 0.1 / 1.
- the catalyst is not found in the ester or in the glycerol.
- No neutralization or washing operation is required to remove the catalyst or a compound derived from the catalyst.
- the glycerol thus obtained has a purity at least equal to 98%. It does not contain metals, no neutralizing salts and its water concentration is limited by those of the starting materials used in the manufacture of Biodiesel, that is to say oil and monoalcohol.
- the glycerol obtained can be used directly in an etherification reaction with isobutene in the presence of an acid catalyst according to a technology well known to those skilled in the art, without prior treatment of this glycerol.
- This reaction is described for example in US-A-1,968,033.
- the composition of the mixture obtained can be changed, either by modifying the glycerol / olefin ratio (for example isobutene ), or by varying the residence time of the mixture on the catalyst.
- the hydrocarbon-soluble glycerol derivative thus obtained (glycerol ether) may be incorporated into a fuel of the diesel, Biodiesel or petrol type.
- glycerol ethers can be introduced into diesel fuels at a concentration such that they are soluble in said fuels. Depending on the case, proportions of 1 to 40% by volume are used, most often from 1 to 20% by volume.
- concentration of glycerol ethers in gasolines can range, for example, up to 50% by volume.
- the process of the invention can be represented by the following diagram: triglyceride methyl esters -> or ethyl oil S (biodiesel conventional inel) > new biodiesel t-butyl ethers meina ⁇ oi J. Ac ⁇ l) glycerol or isobutene ethanol diesel or petrol formulations

In this scheme, all of the initial triglyceride is used as fuel.
- This new Biodiesel can be used as is in a diesel engine or mixed in all proportions with diesel and or a conventional Biodiesel fuel ester. In this scheme, all of the initial triglyceride is used as fuel.
- the glycerol ethers obtained by the manufacturing process according to the invention can also find other applications, for example as solvents, surfactants or co-surfactants.
- the glycerol obtained at the end of the transesterification step or steps can also be used directly in an acetalization reaction with an aldehyde or a ketone or an acetal derived from such an aldehyde or from such a ketone, in particular presence of an acid catalyst according to a technology well known to those skilled in the art, and this without prior treatment of this glycerol.
- Acetalization reactions are described for example in the following documents: J. Gelas: Bulletin Soc. Chimique de France, 1969, n ° 4, 1300; J. Gelas: Bulletin Soc. Chimique de France, 1970, n ° 6, 2341; A J. shower et al: Chem.

In this scheme too, all of the initial triglyceride is used as fuel.
- glycerol obtained by transesterification of a rapeseed oil with methanol was acetalized with acetone to obtain 2,2-dimethyl-1, 3-dioxolane-4-methanol, also sometimes called solketal, and if all of this acetal were incorporated into all of the methyl ester of rapeseed oil obtained, a new Biodiesel would be obtained whose composition would be close to 87.5% by mass of methyl ester of the oil rapeseed and 12.5% by mass of solketal.
