Definitions
- the present invention relates to the field of storage and transport of energy sources and more particularly that of the storage and transport of hydrogen as an energy source, and in particular that of organic compounds capable of storing and transporting hydrogen. 'hydrogen.
- the fixation of hydrogen is generally carried out during a stage of hydrogenation of the support molecule.
- the hydrogenated support molecule “stores” the fixed hydrogen and this so-called “hydrogenated” molecule can be stored and/or transported.
- the fixed hydrogen can then be released, most often near the place of consumption, in a stage of dehydrogenation of the hydrogenated support molecule.
- Carrier molecules are now the subject of numerous studies and are now better known by the acronym LOHC for "Liquid Organic Hydrogen Carrier" in English, that is to say "Organic Liquid Carrier of Hydrogen”.
- toluene which can be hydrogenated to methylcyclohexane and then dehydrogenated.
- One of the problems encountered with this molecule is its relatively low boiling point (110.6°C at atmospheric pressure, certainly higher than that of the hydrogenated form, methylcyclohexane: 100.85°C), which can lead to production of hydrogen containing traces of toluene and/or methylcyclohexane, which may be difficult to get rid of.
- LOHCs known today are aromatic fluids with two or three rings, represented in particular by benzyltoluene (BT) and/or dibenzyltoluene (DBT) and which have already been the subject of numerous studies and patent applications, such as patent EP2925669, for example, which describes the technology and operations for the hydrogenation and dehydrogenation of these fluids for the storage and release of hydrogen.
- BT benzyltoluene
- DBT dibenzyltoluene
- Still other LOHC compounds are being studied and examples are presented in the article by Pàivi et al. ⁇ Journal of Power Sources, 396, (2016), 803-823).
- the hydrogen resulting from this LOHC technology finds uses in very many fields, such as for example in fuel cells, in industrial processes, or even as fuel for means of transport (train, boats , trucks, motor cars). Any impurity potentially harmful to the environment and present in the hydrogen resulting from the dehydrogenation reaction, whether total or partial, of the LOHC molecule, even in trace amounts, could have a negative impact both on the hydrogenation/dehydrogenation process in terms of yield, on the quality of the products manufactured or even on the yields in the end uses of the hydrogen produced by this technique.
- the LOHC compounds known and under development today and listed above are compounds derived from products of fossil origin or synthesized from products of fossil origin.
- the LOHCs known today such as toluene, benzene, and their di- or tri-merized derivatives, such as benzyltoluene (BT) and dibenzyltoluene (DBT), as well as aromatics possibly carrying heteroatoms, in particular derivatives of indole and derivatives of carbazole, are all products derived from petroleum, some of which may have a certain toxicity, or even be harmful vis-à-vis the environment.
- they are of non-renewable origin and may be subject to the vagaries of price variations in crude oil costs.
- a first object of the present invention is the use of a liquid formulation at room temperature comprising at least one terpene derivative for fixing and releasing hydrogen in at least one hydrogenation/dehydrogenation cycle of said formulation .
- terpene derivative within the meaning of the present invention, is meant a product of renewable origin comprising at least one hydrocarbon ring comprising 6 carbon atoms and capable of being hydrogenated and/or dehydrogenated.
- the invention uses products of renewable origin as starting materials.
- the carbon in a product of renewable origin comes from the photosynthesis of plants and therefore from atmospheric CO2.
- biocarbon indicates that the carbon is of renewable origin and comes from a biomaterial, as indicated below. Biocarbon content and biomaterial content are expressions denoting the same value.
- a material of renewable origin also called biomaterial, is an organic material in which the carbon comes from CO2 fixed recently (on a human scale) by photosynthesis from the atmosphere. On land, this CO2 is captured or fixed by plants. At sea, CO2 is captured or fixed by bacteria, cyanobacteria, algae or plankton carrying out photosynthesis.
- a biomaterial (100% carbon of natural origin) has a 14 C/ 12 C isotopic ratio greater than 10' 12 , typically of the order of 1.2 x 10' 12 , whereas a fossil material has a zero ratio.
- the 14 C isotope is formed in the atmosphere and is then integrated by photosynthesis, according to a time scale of a few decades at most. The half-life of 14 C is 5730 years. So the materials resulting from photosynthesis, namely plants in general, necessarily have a maximum content of 14 C isotope. Beyond 50,000 years, the 14 C content becomes difficult to detect.
- the determination of the biomaterial content or biocarbon content is determined by applying the standards ASTM D 6866 (ASTM D 6866-06) and ASTM D 7026 (ASTM D 7026-04).
- ASTM D 6866 is about "Determining the Biobased Content of Natural Range Materials Using Radiocarbon and Isotope Ratio Mass Spectrometry Analysis”
- ASTM D 7026 is about "Sampling and Reporting of Results for Determination of Biobased Content of Materials via Carbon Isotope Analysis”.
- the second standard refers in its first paragraph to the first.
- the first standard describes a test for measuring the 14 C/ 12 C ratio of a sample and compares it with the 14 C/ 12 C ratio of a reference sample of 100% renewable origin, to give a relative percentage carbon of renewable origin in the sample.
- the standard is based on the same concepts as 14 C dating, but without applying the dating equations.
- the ratio thus calculated is designated as the “pMC” (gercent IModern Carbon). If the material to be analyzed is a mixture of biomaterial and fossil material (without radioactive isotope), then the pMC value obtained is directly correlated to the quantity of biomaterial present in the sample.
- the reference value used for the 14 C dating is a value dating from the 1950s. This year was chosen because of the existence of nuclear tests in the atmosphere which introduced large quantities of isotopes into the atmosphere after this date. The 1950 reference corresponds to a pMC value of 100. Taking into account thermonuclear tests, the current value to be used is around 107.5 (which corresponds to a correction factor of 0.93). The radioactive carbon signature of a modern plant is therefore 107.5. A signature of 54 pMC and 99 pMC therefore correspond to a quantity of biomaterial in the sample of 50% and 93%, respectively.
- the ASTM D 6866 standard offers three techniques for measuring the 14 C isotope content:
- this technique consists of counting "beta" particles resulting from the disintegration of 14 C; the beta radiation from a sample of known mass (known number of C atoms) is measured for a certain time; this "radioactivity" is proportional to the number of 14 C atoms, which can thus be determined; the 14 C present in the sample emits beta radiation, which, in contact with the scintillating liquid (scintillator), gives rise to photons; these photons have different energies (between 0 and 156 keV) and form what is called a 14 C spectrum; according to two variants of this method, the analysis relates either to the CO2 previously produced by the carbonaceous sample in a appropriate absorbent solution, or on benzene after prior conversion of the carbonaceous sample to benzene.
- the ASTM D 6866 standard therefore gives two methods A and C, based on this LSC method;
- the terpene derivatives that can be used in the context of the present invention come at least in part from biomaterial and therefore have a biomaterial content of at least 1%. This content is advantageously higher, in particular by at least 20%, better still by at least 40%, advantageously by at least 50%, or even up to 100%.
- the terpene compounds that can be used in the context of the present invention can therefore comprise 100% bio-carbon or, on the contrary, result from a mixture or from reaction products with one or more other compounds of fossil origin.
- formulations comprising at least one terpene derivative in which the ratio (number of carbon atoms of renewable origin/total number of carbon atoms) is greater than or equal to 20%, preferably greater than or equal to 30%, preferably greater than or equal to 40%, and most preferably greater than or equal to 50%.
- terpene derivative an organic compound comprising at least one carbon skeleton of formula (1): in which each "C” represents a carbon atom, bonded to at least one other carbon atom, the total number of carbon atoms being 10, said carbon skeleton of formula (1) not showing the carbon atom(s) hydrogen and/or other substituents, nor any unsaturation(s) in the form of double(s) or triple(s) bond(s) or any other fused ring(s) (s) and/or condensed.

- the skeleton of formula (1) also called “with a limonene structure” in the rest of this description, can also appear, among others and by way of non-limiting examples, in the forms of skeletons of structure (1 ') and (1") following: skeletons of formula (1′) and (1′′) also referred to respectively as “with carene structure” and “with pinene structure” in the rest of this presentation.
- Terpene derivatives with a carene structure or with a pinene structure are not, however, preferred for the use according to the present invention, although they are not excluded therefrom.
- Other compounds of renewable origin comprising the skeleton of formula (1) defined above, also comprise one or more other fused or condensed ring(s), optionally bearing heteroatom(s), forming for example ether, amine and other functions, these functions possibly being intramolecular.
