Definitions

  • the present invention relates to process for producing middle distillates.
  • Object of the present invention is to provide a process for producing ultra low sulphur middle distillates in high yields.
  • This object is achieved when use is made of a particular multi-step process.
  • high yields of middle distillates containing less than 10 ppm sulphur can advantageously be produced from residual hydrocarbonaceous feedstocks.
  • the residual hydrocarbonaceous feedstocks to be used in accordance with the present invention can suitable be residual hydrocarbon oils, such as those obtained in the distillation of crude oils at atmospheric or reduced pressure.
  • at least 75 wt%, more preferably at least 85 wt%, and even more preferably at least 90 wt% of the residual hydrocarbonaceous feedstock has a boiling point of above 550 °C.
  • Atmospheric residues or vacuum residues contain however considerable amounts of non-distillable compounds having a high molecular weight such as asphaltenes. It is therefore considered desirable to remove asphaltenes from a residual hydrocarbon oil feed prior to subjecting the residual hydrocarbon oil to subsequent upgrading steps.
  • a residual hydrocarbonaceous feedstock is deasphalted to obtain a deasphalted product of which at least 50 wt% , preferably at least 70 %, more preferably at least 80 wt%, and even more preferably at least 85 wt% has a boiling point above 550 °C and an asphaltic product.
  • step (a) the deasphalting in step (a) is carried out by means of a solvent deasphalting treatment.
  • paraffinic compounds include C3-8 paraffinic hydrocarbons, such as propane, butane, isobutane, pentane, isopentane, hexane or mixtures of two or more of these.
  • C3-C5 paraffinic hydrocarbons most preferably butane, pentane or a mixture thereof, are used as the extracting solvent.
  • the extraction depth increases at increasing number of carbon atoms of the extracting solvent.
  • a rotating disc contactor or a plate column can be used with the residual hydrocarbonaceous feedstock entering at the top and the extracting solvent entering at the bottom.
  • the lighter hydrocarbons which are present in the residual hydrocarbonaceous feedstock dissolve in the extracting solvent and are withdrawn as the deasphalted product at the top of the apparatus.
  • the asphaltenes which are insoluble in the extracting solvent are withdrawn in the form of the asphaltic product at the bottom of the apparatus.
  • the conditions under which deasphalting takes place are known in the art. Deasphalting is carried out at a total extracting solvent to residual hydrocarbon oil ratio of 1.5 to 8 wt/wt, a pressure of from 1 to 60 bara and a temperature of from 40 to 200 ° C.
  • a deasphalting treatment generally causes a substantial amount of the metallic contaminants present in the feed as high-molecular weight complexes to accumulate in the asphaltic product rather than in the deasphalted product. Nonetheless, the metals content of the deasphalted product will be such that the deasphalted product needs to be subjected to a hydrodemetallizing step before it can be subjected to further hydroprocessing upgrading steps.
  • step (b) at least part of the deasphalted product as obtained in step (a) is hydrodemetallized to obtain a hydrodemetallized product.
  • step (b) the entire deasphalted product as obtained in step (a) is hydrodemetallized.
  • the deasphalted product which is hydrodemetallized in step (b) is a pure and heavy deasphalted product. This means that at least 50 wt%, preferably at least 70 wt%, more preferably at least 80 wt%, and even more preferably at least 85 wt% of the deasphalted product to be treated in step (b) has a boiling point of above 550 °C. Unlike in other hydroconversion processes such as for instance disclosed in EP 1731588 A1 , the entire undiluted deasphalted product as obtained in step (a) can now be hydrodemetallized in step (b), and there is no need to dilute the deasphalted product before it can be further processed.
  • the hydrodemetallisation of the deasphalted product in step (b) can be achieved by any well known hydrodemetallization treatment wherein the deasphalted product to be hydrodemetallized is passed at elevated temperature and pressure and in the presence of hydrogen in an upward, downward or radial direction, through one or more vertically disposed reactors containing a fixed or moving bed of hydrodemetallization catalyst particles.
  • the hydrodemetallization is at least partially carried out in a bunker flow.
  • a hydrodemetallization catalyst for use in step (b), suitably use is made of a hydrodemetallization catalyst.
  • Suitable hydrodemetallization catalysts to be used in accordance with the present invention consist of oxidic carriers such as alumina, silica or silica-alumina, on which one or more Group VIB or Group VIII metals or metal compounds may be deposited.
  • Such hydrodemetallization catalysts are commercially available from many catalyst suppliers.
  • Particularly suitable hydrodemetallization catalysts are those having as the active agent one of the combinations nickel/molybdenum (NiMo) or cobalt/molybdenum (CoMo), optionally promoted with phosphorus (P), on an alumina (Al2O3) carrier. Concrete examples of particularly suitable catalysts are CoMo/A1203, CoMoP/Al2O3 and NiMo/A1203 and NiMoP/Al2O3 catalysts.

  • the hydrodemetallization reactor is preferably a bunker flow reactor, a fixed bed swing reactor or a movable bed reactor.
  • the hydrodemetallization catalyst(s) is (are) regularly replaced for instance every three weeks or two months, whereas in conventional processes the hydrodemetallization catalyst(s) (like the hydrotreating and hydrocracking catalysts to be used in steps (c) and (d) in the present process) may not be replaced within a year time.
  • step (c) at least part of the hydrodemetallized product as obtained in step (b) is hydrotreated to obtain a hydrotreated product.
  • step (c) the entire hydrodemetallized product as obtained in step (b) is hydrotreated.
  • the hydrotreating of the hydrodemetallized product in step (c) can be achieved by any well known hydrotreating process wherein the hydrodemetallized product to be hydrotreated is passed at elevated temperature and pressure and in the presence of hydrogen in an upward, downward or radial direction, through one or more vertically disposed reactors containing a fixed or moving bed of hydrotreating catalyst particles.
  • the hydrotreatment can be carried out in a bunker flow reactor, a fixed bed reactor, a fixed bed swing reactor or a movable bed reactor.
  • the hydrotreatment in step (c) is carried out in two reaction zones, whereby the hydrodemetallized product is first passed to a first reaction zone in which the hydrodemetallized product is partly hydrotreated after which the partly hydrotreated effluent so obtained is subjected to further hydrotreatment in a second reaction zone.
  • the first reaction zone and second reaction zone can be arranged in a stacked bed configuration or the two reactions zones can each be arranged in a separate reactor.

  • a hydrodesulphurization catalyst comprising compounds of nickel and/or cobalt and molybdenum as hydrogenation compounds is preferred.
  • the hydrodesulphurization catalyst may further comprise a cracking component such as for example Y zeolite. It is, however, preferred that no substantial hydrocracking takes place in the hydrotreatment in step (c). Therefore, it is preferred that the catalyst is substantially free of a cracking component.
  • the hydrotreating conditions in step (c), i.e. temperature, pressure, hydrogen supply rate, weight hourly velocity of the feedstock, are typical hydrotreating conditions.
  • the temperature used for the hydrotreating in step (c) is in the range of from 280 to 430 °C, more preferably in the range of from 320 to 420 °C, and most preferably in the range of from 330 to 410 °C.
