- the catalytic beds are generally fixed catalytic beds.
- the hydrogenation step can be implemented in two or three reactors, preferably three reactors and is more preferably carried out in three reactors in series.
- the first reactor allows the trapping of sulfur compounds and the hydrogenation of essentially all the unsaturated compounds and up to around 90% of the aromatic compounds.
- the product from the first reactor contains substantially no sulfur compound.
- the hydrogenation of the aromatics continues and up to 99% of the aromatics are therefore hydrogenated.

- the first reactor is composed of twin reactors implemented in an alternative way. This mode of operability allows in particular easy loading and unloading of the catalysts: when the first reactor includes the saturated catalyst first (substantially all the sulfur is trapped on and/or in the catalyst) it must be changed often.
- a single reactor can also be used in which two, three or more catalytic beds are installed.
- quench boxes in the English sense of "reaction quenching"
- reaction quenching it may be necessary to insert quench boxes (in the English sense of "reaction quenching") in the recycling system or between the reactors to cool the effluents from one reactor to another or from a catalytic bed to another to control the temperatures and hydrothermal equilibrium of each reaction.
- quench boxes in the English sense of "reaction quenching"
- the product resulting from stage b) of hydrogenation and/or the separated gases are at least partly recycled in the supply system of the hydrogenation reactors. This dilution helps to keep the exothermicity of the reaction within controlled limits, especially in the early stage. Recycling further allows heat exchange prior to the reaction and also better temperature control.
- the process of the invention further comprises recycling part of the hydrogenated hydrocarbon feedstock obtained at the end of stage b) of hydrogenation in order to be mixed with the hydrocarbon feedstock available in stage a) upstream of stage b) of hydrogenation.
