Definitions
- the invention relates to a process with hydrocracking at moderate pressure, for the production of very high quality diesel with high yields.
- the invention also relates to a process including said hydrocracking process and a catalytic cracking process, as well as the installation usable for implementing said process.
- the refining industry must now find refining schemes to adapt to the tightening of fuel quality standards which will be in force in Europe in 2005.
- the maximum sulfur content in diesel must be at most 50 ppm.
- the 95% distillation point (ASTM D-86) of diesel, currently 360 ° C, will probably be reduced, for example by 10 ° C, which would currently represent for a refinery a decrease of 5% in volume of diesel produced. It is also envisaged to divide at least in half the present polyaromatic contents which are approximately 11% by mass. Currently. The cetane number required would also be increased beyond 51, for example from the current value of 51 to 52.
- 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 crude distillation diesel will have to undergo deep hydrodesulfurization.
- high pressure hydrocracking is a solution which can prove to be expensive.
- the process set out in the present application is a hydrocracking process operating at moderate pressures (above 70 bars and at most 100 bars under partial hydrogen pressure) which makes it possible to directly obtain a diesel which meets the 2005 specifications at from relatively light loads in more economical conditions than high pressure hydrocracking.
- 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 feeds treated in the process have a point T 5 of between 250 and 400 ° C and preferably between 280 and 370 ° C.
- the point T 5 represents the temperature of the point 5% volume obtained by simulated distillation (ASTM-D28 87).
- the charges have a point T 5 between 320-400 ° C or between 320-370 ° C.
- a fraction of the diesel for example heavy diesel obtained from the atmospheric distillation of crude oil, which most often has a point T 5 of the order of at least 280 ° C., can be added to these charges. This heavy diesel fraction can just as easily be obtained directly in the atmospheric residue.
- This arrangement (addition of diesel) is particularly advantageous. Indeed, it makes it possible to treat, by hydrotreatment followed by hydrocracking at moderate pressure, a heavy part of the diesel fraction which is loaded with nitrogen and sulfur compounds which are the most difficult to hydrotreat. Therefore, a conventional hydrotreatment can be used to treat the remaining diesel fraction, and there is no need for costly investment.
- this heavy part of the diesel in the process according to the invention the hydrodesulfurization of the heavy fraction is carried out with at the same time an improvement in its qualities (cetane index higher than that which would have been obtained by severe hydrotreatment alone) .
- 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).
- VGO vacuum gas oil
- HGO heavy atmospheric gas oils
- the hydrocarbon feedstocks treated generally have sulfur contents of 0.2 to 4% by mass and nitrogen contents of 100-3500 ppm by mass. They are therefore generally hydrotreated before being hydrocracked so as to lower the contents of organic nitrogen (that is to say of nitrogen forming part of organic molecules) below 80 ppm, or better still of 50 ppm and preferably below 10 ppm, and the contents of organic sulfur, (that is to say sulfur forming part of organic molecules) below 200 ppm and preferably below 50 ppm. These hydrotreated fillers (called clean) can then be subjected to hydrocracking.

Also included in the process is an embodiment in which the hydrotreating is carried out in the refinery very upstream from the hydrocracking, intermediate treatments may also be carried out.
- the clean charge is, at least in part, in the presence of hydrogen brought into contact with at least one hydrocracking catalyst under the following operating conditions:
- the process can operate with or without recycling the distillation residue from the hydrocracking effluent (fraction not converted).

- Peak rates and crystal fractions are determined by X-ray diffraction using a procedure derived from ASTM D3906-97 "Determination of Relative X-ray Diffraction Intensifies of Faujasite-Type-Containing Materials". This method may be referred to for the general conditions of application of the procedure and, in particular, for the preparation of samples and references.

More generally, it will be possible to start from zeolites having a crystalline fraction of at least 60%, or at least 70%.
- the Y zeolites generally used in hydrocracking catalysts are manufactured by modification of commercially available Na-Y zeolite. This modification leads to so-called stabilized, ultra-stabilized or dealuminated zeolites. This modification is carried out by at least one of the dealumination techniques, and for example the hydrothermal treatment, the acid attack. Preferably, this modification is carried out by combination of three types of operations known to those skilled in the art: hydrothermal treatment, ion exchange and acid attack.

- the crystalline parameter of this zeolite may have decreased by extraction of the aluminum from the structure or frame during the preparation, but the ratio Overall SiO 2 / Al 2 0 3 did not change because the aluminum was not extracted chemically.
- Such a globally non dealuminated zeolite therefore has a silicon and aluminum composition expressed by the overall SiO 2 / Al 2 0 3 ratio equivalent to the starting non dealuminated Y zeolite.
- This globally non dealuminated Y zeolite can be in the hydrogen form or be at least partially exchanged with metal cations, for example using cations, alkaline earth metals and / or rare earth metal cations with atomic number 57 to 71 inclusive.

- the generally non dealuminated zeolite can be obtained by any treatment which does not extract the aluminum from the sample, such as, for example, treatment with steam, treatment with SiCI, etc.
- Another type of catalyst advantageous for hydrocracking contains an acidic amorphous oxide matrix of the alumina type doped with phosphorus, a zeolite Y not dealuminated overall and very acidic and optionally at least one element of group VIIA and in particular fluorine.
- the invention is not limited to the cited and preferred Y zeolites, but other types of Y zeolites can be used in this process.
- the catalyst Prior to injection of the feed, the catalyst is subjected to a sulfurization treatment making it possible to transform, at least in part, the metallic species into sulphide before they are brought into contact with the feed to be treated.
- This activation treatment by sulfurization is well known to those skilled in the art and can be carried out by any method already described in the literature either in situ, that is to say in the reactor, or ex situ.
- a conventional sulfurization method well known to those skilled in the art consists in heating in the presence of hydrogen sulfide (pure or for example under a flow of a hydrogen / hydrogen sulfide mixture) to a temperature between 150 and 800 ° C., preferably between 250 and 600 ° C, generally in a reaction zone with a crossed bed.

- the liquid effluent from hydrocracking is then distilled so as to separate a naphtha cut, a diesel cut, possibly a kerosene cut (which can sometimes be included at least partially in the diesel cut), the LPG light gases. There remains a liquid residue which can advantageously be recycled in the process after purging generally.
- the method makes it possible to directly produce a diesel having a 95% volume distillation point less than 360 ° C, and generally this point is at most 350 ° C or even at most 340 ° C, having a sulfur content at most 50 ppm, and generally at most 10 ppm, having a cetane number of at least 52 and most generally of at least 54 and preferably having a polyaromatic content of at most 6% by weight and generally at most 1%, and preferably a pour point of less than -10 ° C, and preferably an aromatic content of less than 15% by weight.

- the atmospheric residue leaving via line 25 is vacuum distilled in the vacuum distillation column 26. There is separated a vacuum distillate fraction (line 27) and there remains a vacuum residue (line 38).
- Said vacuum distillate is sent to a catalytic cracking unit 28 (generally in a fluidized bed) which by this process produces, inter alia, naphtha discharged through line 29, a fraction of highly aromatic diesel type (light cycle oil LCO) evacuated via line 30, and a "slurry" or residue leaving via line 31.
- a catalytic cracking unit 28 generally in a fluidized bed
- the vacuum residue is treated in a viscoreduction unit 39, which produces, inter alia, naphtha (line 40) and diesel (line 41) which are of low quality.
- the viscoreduction residue (line 42) can only be used as fuel as well as the slurry, part of the LCO can be used to flux this fuel.
- FIG. 2B shows the process and the installation according to the invention, combining hydrocracking at moderate pressure and catalytic cracking.
- FIG. 2B The installation according to the invention (FIG. 2B) comprises, in addition to that of the prior art (FIG. 2A), the hydrocracking unit 32 at moderate pressure which receives a light fraction resulting from the vacuum distillation brought into the driving 33.
- Unit 32 includes the hydrocracking reactor (s) or zone (s) at moderate pressure and the associated separations making it possible to exit, inter alia, via a line 34 a high quality diesel, through line 35 a naphtha and via a line 36 the purging of the hydrocracking residue.
- the unit 32 also includes a hydrotreating zone before hydrocracking.
- the hydrocracking residue can at least partly be sent to catalytic cracking (unit 28) but without this being compulsory.

- the atmospheric residue which therefore contains at least part of the heavy atmospheric diesel, is vacuum distilled into at least one light fraction (distillate) and at least one heavy fraction (distillate), and there remains a vacuum residue.
- Said light fraction to be treated by hydrocracking has a temperature T 5 which is between 250 and 400 ° C and a temperature T 95 which is at most 470 ° C. It is a light vacuum diesel fuel (LVGO).
- LVGO light vacuum diesel fuel
- the final boiling point is chosen by the operator according to the column at his disposal and according to the recovery desired by the products.
- Said light fraction has the other characteristics of the hydrocarbon feedstocks treated by the process according to the invention and described above.
- this light vacuum distillate treatment by moderate pressure hydrocracking can be implemented when the production and / or quality of diesel want to be increased, regardless of the type of treatment reserved for the distillate (s) heavy (s) and residue from vacuum distillation.
- the vacuum distillation residue (line 38) which generally has a temperature T 5 of at least 535 ° C, preferably at least 550 ° C, or even at least 565 ° C or 570 ° C, can be subjected for example to a viscoreduction (shown in FIG. 1) or to a hydroconversion of residue or a coking.
- At least one so-called heavy vacuum distillate fraction situated between the light fraction having a temperature T 95 of at most 470 ° C., and the vacuum residue, is subjected to catalytic cracking.
- FIG. 3 represents an installation and a process in which the heavy fraction resulting from vacuum distillation and which is subjected to catalytic cracking, is, before said cracking, subjected to hydrotreatment in a zone 43.
- the references of the previous figures are repeated here.
- This hydrotreatment before the FCC takes place in the presence of at least one amorphous catalyst All conventional hydrotreatment catalysts can be used. Mention will be made of the catalysts containing at least one element from the non-noble group VIII (Co, Ni for example) and at least one element from the group VIB (Mo, W for example) deposited on a support preferably based on alumina or silica -alumina.
- the particularity of this step lies in its operating conditions: a partial hydrogen pressure between 25 and 90 bars, preferably less than 85 bars, or even less than 80 bars, or even less than 70 bars, and a temperature of 350- 450 ° C, preferably 370-430 ° C adjusted so as to maintain a conversion of at least 10% and preferably less than 40% in products boiling below 350 ° C and preferably 15-30%.
- a naphtha line 44
- a diesel line 45
- 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.
- Diesel has a cetane number of 49 and a sulfur content of 2,100 ppm. To meet specifications (cetane 51 and sulfur 350 ppm), it must undergo conventional desulfurization. Without change in the refinery diagram, but with diesel qualities to the 2005 specifications (95% point taken at 340 ° C), we have (diagram 2):
- Diesel has a cetane number of only 48 and must therefore undergo extremely severe hydrodesulfurization and hydrogenation which it is not possible to carry out in current units.
- 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.
- Cetane from diesel remains at about 48.
- FCC naphtha has a sulfur content of 15 ppm, and in the naphtha pool the sulfur content can then be lowered to as low as about 5.5 ppm, without loss of sensitive octane.
- vacuum distillation separates a light fraction 350-410 ° C, a heavy fraction 410-565 ° C and a residue 565 ° C +.
