Definitions
- the present invention relates to the field of liquid formulations capable of transporting hydrogen, and more particularly the field of formulations based on benzyltoluene capable of transporting hydrogen.
- Hydrogen today represents an alternative to fossil, natural or electrical energy sources.
- the storage and transport of this energy source, hydrogen remains a major challenge for the rapid and accessible development of this energy source.
- the principle of this LOHC technology consists in fixing hydrogen on a support molecule, which is preferably and most often liquid at room temperature, in a hydrogenation step, then in releasing the fixed hydrogen, at near the place of consumption, in a dehydrogenation step.
- Patent EP2925669 thus shows the use of BT and/or DBT in LOHC technology, and describes the hydrogenation and dehydrogenation operations of these fluids for the storage and release of hydrogen.
- the sequence of cycles and the maintenance of performance are key points for the economic aspect of this technology.
- the hydrogen resulting from this LOHC technology finds uses in very many fields, such as for example in fuel cells, as well as in various industrial processes, or even as fuel for all means of transport, such as trains, ships, trucks, motor cars, planes, and others. Any impurity present in the hydrogen, even in trace amounts, could have a negative impact, both on the hydrogenation/dehydrogenation process in terms of yield, and on the quality of the products manufactured or even on the yields in end uses. hydrogen produced by this technique.
- the present invention relates to a liquid formulation, based on benzyltoluene and containing very low levels of light hydrocarbons.
- This type of formulation makes it possible in particular to overcome all or part of the drawbacks noted in the prior art for LOHC fluids, by meeting in particular the requirements for storage, transport and removal of hydrogen, under optimal industrial and economic conditions, and in allowing the release, during the dehydrogenation step of said formulation, of hydrogen having a high purity, and in particular of hydrogen having a very low content of light hydrocarbons, these being particularly detrimental for the uses of hydrogen in a large number of applications, such as fuel cells for example.

It has in fact been observed that hydrocarbons, and in particular so-called "light" hydrocarbons, and more precisely hydrocarbons with a molar mass equal to or less than 100 g mol -1 , very often lead to numerous disadvantages, whether during hydrogenation/dehydrogenation operations to which the LOHC formulations are subjected, but also in the hydrogen released during the dehydrogenation operations, hydrogen which may then not have the degree of purity required for the applications for which it is intended.
- Light hydrocarbons can in fact disrupt the hydrogenation/dehydrogenation reactions, and typically by degradation and/or total or partial deactivation of at least some of the catalysts used, lower yields of the hydrogenation/dehydrogenation cycles, or any other effect disturbing the operating conditions of said hydrogenation/dehydrogenation cycles.

- the performance of the hydrogenation/dehydrogenation cycles are facilitated/improved, thanks to less degradation of the catalyst during successive cycles, in particular due to the fact that the LOHC formulation of the invention includes only traces of light hydrocarbons, as discussed above, hydrocarbons which are known to be catalyst poisons commonly used in hydrogenation/dehydrogenation reactions.
- the hydrogen stored and then released during the dehydrogenation step is high purity hydrogen, which can thus find uses in a very large number of applications, in particular for fuel cells, and all other industrial applications requiring the use of high purity hydrogen, such as the electronics sector for the production of microprocessors, semiconductors, and others.
