Definitions
- the present invention relates to the field of fuels for combustion engines internal. It relates more particularly to the conversion of a diesel cut and in particular the manufacture of a fuel for a compression ignition engine. She also relates to the fuel thus obtained.
- diesel fractions whether they come from the direct distillation of a crude oil or whether they come from a conversion process such as cracking catalytic, still contain significant amounts of compounds aromatic, nitrogen and sulfur.
- a fuel must have a cetane number greater than 51, a sulfur content less than 350 ppm (parts per million by mass), a density, d15 / 4, at 15 ° C less than 0.845 g / cm 3 , a content of polyaromatic compounds of less than 11% by weight and a boiling point of 95% of its components, T95, of less than 360 ° C.
- the diesel cuts generally come either from direct distillation of crude or from catalytic cracking: i.e. cuts of light distillates (Anglo-Saxon initials LCO for Light Cycle Oil), heavy fraction cuts (HCO initials) for Heavy Cycle Oil), or another conversion process (coking, visbreaking, hydroconversion of residue etc.) or even diesel fuels from the distillation of crude oil aromatic or naphthenoaromatic of the Cerro-Negro, Zuata, El Pao type. It is particularly important to produce an effluent that can be directly and fully valued as a very high quality fuel cutter.
- Patent FR 2 777 290 proposes a process combining hydrocracking with a hydrogenation in order to decrease the sulfur content and increase the cetane of the fuels thus produced. This process, which already has good performance, must however be improved in order to meet the increasingly stringent requirements that will be required in most countries industrialized.
- the diesel fillers to be treated are generally light diesel, for example direct distillation gas oils, fluid catalytic cracking gas oils (initials Anglo-Saxon FCC for Fluid Catalytic Cracking) or (LCO). They present generally an initial boiling point of at least 180 ° C and a final boiling point of at most 370 ° C.
- the weight composition of these charges by family of hydrocarbons is variable depending on the intervals. According to the compositions usually encountered, the paraffin contents are between 5.0 and 30.0% by weight and naphthenes between 5.0 and 60% by weight.
- the diesel fillers preferably have a content of aromatic compounds (including polyaromatic and naphthenoaromatic compounds) between 20% and 90%, in especially between 40% and 80% by weight.
- the process according to the invention makes it possible, during the first hydrorefining step, to reduce sulfur content, nitrogen content, aromatic content and polyaromatics, as well as increasing the cetane number.
- the conversion to products having a boiling point below 150 ° C is limited to the hydrorefining stage. So converting into products having a boiling point below 150 ° C is, for the hydrorefining step, included between 1 and 15%, preferably 5 and 15% by weight.
- the operating conditions to apply to respect these conversion rates favor the reduction of the content of compounds aromatics by hydrogenating them and increasing the cetane number.
- the conversion to products with a boiling point below 150 ° C is also, for all of the two hydrorefining and hydrocracking stages, kept below a certain limit, beyond which it was found that the index cetane could be reduced due to the presence of aromatic compounds. So, the conversion to products with a boiling point below 150 ° C is, overall of the two hydrorefining and hydrocracking stages, less than 40%, preferably less than 35%, in particular less than 30%, for example less than 25% by weight.
- a zeolitic catalyst is used during the step hydrocracking at a temperature lower than that of the hydrorefining step. He was noticed with surprise that this made it possible to complete the hydrogenation of the compounds aromatics and polyaromatics while allowing, nevertheless, to achieve a moderate cracking of the charge, since said cracking is carried out at temperatures relatively low.
- the difference between the temperature TR1 of the hydrorefining stage and the hydrocracking temperature TR2 of the step is between 0 and 80 ° C.
- This gap is preferably between 5 ° C and 70 ° C, especially between 10 ° C and 60 ° C, in especially between 15 ° C and 50 ° C.
- this difference can be between 11 ° C and 70 ° C, preferably between 13 ° C and 60 ° C, in particular between 15 ° C and 50 ° C.
- the process of the invention thus makes it possible to increase, during the hydrocracking step, the number of cetane while decreasing the density, d15 / 4, and the temperature, T95, of the cut diesel.
- the fuel produced thus meets the most stringent future specifications.
- the catalyst used during the hydrorefining step of the process of present invention also called hydrorefining catalyst, comprises on a amorphous mineral support, at least one metal from group VIB of the periodic table elements, at least one non-noble metal from group VIII of this same classification and at least one promoter element.

- This type of catalyst has also a higher hydrocracking activity and selectivity than the catalytic formulas known in the prior art.
- a catalyst comprising boron and silicon is particularly active, which induces, on the one hand, an improvement in hydrogenating, hydrodesulfurizing, hydrodenitrogenating properties and, on the other hand, a improvement in hydrocracking activity compared to the catalysts used usually in hydroconversion hydrorefining reactions.

- Peak rates and crystal fractions are determined by X-ray diffraction compared to a reference zeolite, using a procedure derived from the method ASTM D3906-97 "Determination of Relative X-ray Diffraction Intensities of Faujasite-Type-Containing Materials ”. We can refer to this method for the conditions terms of application of the procedure and, in particular, for the preparation of samples and references.
- a diffractogram is composed of the lines characteristic of the crystallized fraction of the sample and of a background, essentially caused by the diffusion of the amorphous or microcrystalline fraction of the sample (a weak diffusion signal is linked to the apparatus, air, sample holder, etc.).

- the crystalline parameter can be reduced by extraction of the aluminum from the structure (or framework).
- the overall SiO 2 / Al 2 O 3 ratio generally remains unchanged because the aluminum has not been chemically extracted.
- Such a globally non dealuminated zeolite therefore has an overall SiO 2 / Al 2 O 3 ratio which also remains unchanged.

This zeolite can be used in its acid form H-NU-86 or partially exchanged by cations. The NU-86 zeolite can also be used after undergoing treatment (s) post-synthesis dealumination so as to increase and adjust its Si / Al ratio thus its catalytic properties. Post-synthesis dealumination techniques are described in US Patent 6,165,439.
- the hydrorefining and / or hydrocracking catalyst can be subjected to a sulfurization treatment making it possible to transform, at least in part, the species metallic sulphide before their contact with the load to be treated.
- This treatment of activation by sulfurization is well known to the skilled person and can be carried out by any method already described in the literature either in situ, i.e. in the reactor, or ex situ.
