Definitions
- the invention relates to the fields of conversion and / or treatment of residues from the distillation of petroleum, liquid hydrocarbon feeds from the liquefaction of coal and crude oils.
- the present invention relates to a sequence of two hydrocarbon treatment processes:
- the first (hydroconversion) comprising at least one reaction chamber and preferably a succession of reaction chambers, the reaction or reactions occurring inside said chambers and involving at least one solid phase, at least one liquid phase and at least one gaseous phase,
- the second comprising at least one reaction chamber and preferably a succession of reaction chambers, the reaction or reactions occurring inside said chambers make it possible to produce a reagent necessary for the chemical reactions of the first.
- US Pat. No. 4,526,676 uses as a feedstock of the gasification unit a combination of light hydrocarbons in gaseous form, as well as the heavier part produced by the process (bottom of the vacuum column).
- gasification is necessary.
- a dedicated oxygen purification unit is necessary, which makes it more complex to install such a complex on the extraction site of the crudes which, it will be remembered, are generally in difficult locations. access, away from industrial centers and communication nodes.
- GB 1 092 420 discloses a process for the conversion of hydrocarbon distillate to recoverable gases. The process combines at least one hydrocracking stage with two gasification stages, these two gasification stages being hydrogen-producing vapor reforming stages.
- the effluent leaving the hydrocracking zone is separated into two fractions: a first lighter fraction passes into a first vapor reforming zone to give a gas rich in methane and the second heavier fraction passes into a second vapor reforming zone to give a gas rich in H2, part of which is recycled in the hydrocracking zone.
- U.S. Patent 3,552,924 discloses a process for producing hydrogen from an excess refining stream having compounds having a carbon number of greater than 6 to heavy oils.
- the feedstock is hydrocracked by adding hydrogen to a hydrocracking zone.
- the hydrocracking effluent is cooled to condense hydrocarbons having a carbon number greater than 6.
- the resulting vapor fraction is passed over a reforming steam catalyst through a vapor reforming zone to produce carbon monoxide. , carbon dioxide and hydrogen, this effluent then passes through a conversion step which converts the carbon monoxide to carbon dioxide and hydrogen and the gaseous effluent from the conversion reaction is separated into a stream hydrogen and a stream of carbon dioxide, a portion of the hydrogen stream being recycled to the hydrocracking step.
- the hydrogen necessary for the treatment of the charges is manufactured in the steam reformer by a contribution of natural gas generally present at the site where the charges are extracted.
- This natural gas can be expensive because of the market or by transport to the relocated heavy oil production site.
- the invention overcomes at least partially this disadvantage by using some or all of the light gases produced during the hydroconversion to produce hydrogen or part of the necessary hydrogen. These gases are produced in the reactors and can be extracted downstream of the different reaction capacities or just after each reaction capacity.
- the invention describes a sequence of processes for treating hydrocarbons as described at the beginning of the text completely independently. This invention is particularly suitable for deposits located in hard-to-reach geographical areas.

- the second downstream process comprises a first so-called pre-reforming step which makes it possible to convert at least partially, and preferably with a conversion greater than 95% by weight, hydrocarbons heavier than methane to methane, which increases the efficiency of the whole.
- the sequence of these two processes allows the complex to be self-sufficient in hydrogen, with a low input of natural gas (generally less than 3% by weight relative to the feedstock for conversions of about 60% by weight of the 540 ° compounds. C + and generally less than 1% by weight relative to the feedstock for conversions of about 90% by weight of the compounds 540 ° C +), or even without external input of natural gas (other than for furnace burners).
- the upstream hydrocarbon conversion process comprises a zone for contacting a liquid feedstock, a gaseous feedstock and solid particles constituting the solid phase, the said particles preferably having a catalytic activity.
- Said solid particles may be dispersed in a suspension immersed in a liquid phase in a lower zone of the enclosure, then generally referred to as the Anglo-Saxon "slurry" reactor.
- the catalytic agent then passes through the reaction zone without being separated from the liquid in the reactor.
- the size of the particles of the catalytic phase formed in this type of process remains small enough that it is difficult to fluidize these particles in the reaction zone without drawing them with the liquid (generally the order of 100 microns, preferably less than 10 microns).
- the catalyst (catalytic solid particles) is generally introduced continuously with the fresh feedstock into the reactor and consists of a soluble element containing one or more metals which can be sulphurated under the conditions of the feedstock. process.
- Said solid particles may also be present in a bubbling bed.
- the bubbling bed process employs a supported catalyst containing at least one metallic element: the catalytic action of which is in the form of sulphide, the size of which is such that the catalyst remains generally in the reactor.
- the liquid velocity in the reactor makes it possible to fluidize this catalyst but does not make it possible to drive it outside the reaction zone with the liquid effluents. Continuous addition and removal of catalyst is possible and makes it possible to compensate for deactivation of the catalyst.
- the upstream hydroconversion process is also implemented by combining the "slurry" mode and the bubbling bed by injecting the fine particles or precursors of fine particles at the level of the liquid feedstock upstream of the reactor and passing them through the reactor operating in a bubbling bed.

- the fraction boiling at temperatures above 565 ° C. is generally greater than 10% by weight of the total fraction, preferably greater than 50% by weight.
- these metals are deposited on the catalysts, accumulate on them and deactivate It must therefore regularly add catalyst fresh (without metals) to maintain catalytic activity.
- This catalyst addition is easily effected if the reaction is carried out in a bubbling bed and / or in slurry. Indeed, the method in "slurry" mode and / or bubbling bed allows the addition of fresh catalyst containing no metals and the withdrawal of catalyst containing metals continuously.
- These fillers are also characterized by the fact that they contain significant quantities of asphaltene, that is to say a content by weight greater than "0.5%, preferably a content of between 2 and 20% and of very preferably, between 3 and 15%.

- the upstream process is carried out either in a "slurry" mode, or in a bubbling bed process, or in combination of the two modes.
- said second downstream process comprises a first so-called pre-reforming step which allows to convert at least partially, and preferably with a conversion greater than 95% by weight, hydrocarbons heavier than methane to methane which increases the efficiency of the whole.
- the upstream process comprises a zone for contacting a liquid feedstock, a gaseous feedstock and solid particles.
