Definitions

  • the invention relates to a process with hydrocracking at moderate pressure, for the production of very high quality diesel with high yields.
  • diesel Since the distillation of crude oil is not sufficient to cover the production of diesel, diesel is currently produced by hydrocracking processes at high pressure (generally at least 120 bars in partial hydrogen pressure) treating heavy loads which are fillers having a temperature Tgs most often of the order of at least 500 ° C., T 95 being the temperature of the point 95% volume obtained by simulated distillation (ASTM-D28 87). Heavy compounds are cracked into lighter compounds, part of which is found in the middle distillate cut (diesel and kerosene) from the hydrocracking distillation. Such high pressure processes are conventional.
  • the invention relates to a method for producing a diesel having a 95% distillation point of less than 360 ° C., a sulfur content of at most 50 ppm and a cetane number greater than 51, said method treating fillers.
  • hydrocarbons having a temperature T 5 of between 250 and 400 ° C and a temperature T 95 of at most 470 ° C, said process comprising hydrotreatment and then hydrocracking under a partial pressure of hydrogen greater than 70 bars and at most 100 bars, ' at a temperature of at least 320 ° C, with a H2 / load volume ratio of at least 200 NI / NI, an hourly volume speed of 0.15-7h "1 and the process carrying out a conversion d at least 80% by volume and the liquid effluent obtained by hydrocracking being distilled to separate the diesel, preferably the distillation residue is recycled in the process after purging.
  • the fillers which can also be used have a temperature T 95 of at most 470 ° C, or better still of at most 450 ° C, or better understood in the range 390-430 ° C, T 95 representing the temperature of the point 95% obtained by simulated distillation (ASTM-D28 87).
  • H2 / load volume ratio of at least 100 Nl / I, and most often between 100-2000 Nl / l or even 300-2000 Nl / i, hourly volume speed of 0.1-1 Oh "1 , preferably 0.15-7h " 1 , and advantageously 0.05-4h "1 .
  • the conversion carried out in the hydrotreatment is generally at least 10% by volume and less than 40% in product boiling below 350 ° C.
  • catalysts which contain at least one amorphous support and at least one hydro-dehydrogenating element (generally at least one element from groups VIB and VIII non-noble, and most often at least one element from group VIB and at least a non-noble element of group VIII).
  • this catalyst contains boron and / or silicon as a promoter element, optionally with phosphorus as another promoter element.

  • silica silica-alumina
  • clays for example among natural clays such as kaolin or bentonite
  • magnesia titanium oxide, boron oxide, zirconia, aluminum phosphates, titanium phosphates, zirconium phosphates, carbon, aluminates.
  • alumina containing alumina, in all these known forms skilled in the art, and even more preferably aluminas, for example gamma alumina.
  • This catalyst may advantageously contain phosphorus; in fact, it is known in the prior art that this compound provides two advantages to hydrotreatment catalysts: ease of preparation during in particular the impregnation of nickel and molybdenum solutions, and better hydrogenation activity.
  • the total concentration of metal oxides of groups VI and Vlll is between 5 and 40% by weight and preferably between 7 and 30% and the weight ratio expressed as metal oxide between metal (or metals) of the group VIB on metal (or metals) of group V111 is preferably between 20 and 1.25 and even more preferred between 10 and 2.
  • the concentration of phosphorus oxide P2O5 will be less than 15% by weight and preferably 10% by weight.

  • the reactor 7 contains at least one catalytic bed 8 of at least one hydrocracking catalyst. Preferably, it can contain upstream of the first bed 8 at least one hydrotreating catalyst.
  • the liquid effluent from the reactor and leaving via line 9 passes through the exchanger 4 and then in a gas-liquid separator 10 separating the hydrogen which is recycled through line 5 to the hydrocracking reactor 7.
  • the hydrotreated effluent then passes through the catalytic cracking unit 28.
  • a contribution of heavy diesel fraction has been schematically represented in unit 32 where hydrocracking is carried out at moderate pressure.
  • it is obtained by atmospheric distillation, in addition to the naphtha (line 22), kerosene (line 23) cuts, a light diesel fraction LGO (line 46) and a heavy diesel fraction HGO (line 47).
  • This heavy diesel fraction is sent to unit 32 where it will undergo hydrotreatment then hydrocracking at moderate pressure.
  • the present application describes a process for producing diesel and naphtha, the production of diesel being carried out by a hydrocracking process at moderate pressure as set out above, and the production of naphtha being obtained essentially by catalytic cracking.
  • the hydrocracking purge is sent to catalytic cracking.
  • the naphtha pool would have a sulfur content of 270 ppm by mass, which would require severe subsequent treatments to reduce it to 10-50 ppm by mass. Also, to avoid costly investments, the naphtha fraction from the FCC will be treated separately in severe hydrodesulfurization, with the drawback of lowering the octane number. The other naphtha fractions (for example from the visbreaker, from the distillation of crude ...) will be sent to reforming and possibly an isomerization unit after hydrotreatment.
