Definitions
- the present invention relates to the field of reactors with radial flow of the hydrocarbon feedstock to be treated. It applies more particularly to the catalytic reforming of gasolines.
- the invention makes it possible to use very small amounts of catalyst and thus to control residence times of low value.
- Catalytic bed reactors with a radial circulation of the hydrocarbon feedstock to be treated are known in the field of refining.
- such reactors are used to carry out catalytic reforming reactions which aims to convert C7-C10 paraffinic and C7-C10 naphthenic compounds to aromatic compounds with the associated production of hydrogen.
- the catalytic conversion is generally carried out at high temperature, of the order of 500 ° C., at a mean pressure of between 0.1 and 4.0 MPa and in the presence of a specific reforming catalyst so as to produce a high-index reformate.
- octane rich in aromatic compounds that can serve as a fuel base.
- the constraints related to mobile radial bed technology are multiple.
- the speeds of the hydrocarbon feedstock to be treated during the crossing of the catalytic bed are limited to prevent cavitation at the entrance of the bed (when the latter is a moving bed), to avoid blockage of the catalyst at its outlet against the internal grid , and to reduce the pressure drops (function of the speed and the thickness of the bed).
- a too high charge rate will lead to the catalyst blocking phenomenon against the central collector (or "pinning" in the English terminology).
- the force exerted by the load flowing radially from the outer periphery of the catalyst bed towards the center of the reactor deposits the catalyst grains against the wall of the central collector, which increases the frictional stress which then opposes the slippage of the grains. along the wall.
- the resulting frictional force is sufficient to support the weight of the catalyst bed so that the gravitational flow of the catalyst grains ceases, at least in some regions adjacent to the collector wall. central. In these regions, the catalyst grains are then "pinned"("pinned” in the English terminology) by the flow of the load and are held stationary against the wall of the collector.
- the phenomenon of immobilization of the catalyst particles is strongly avoided in catalytic reforming reactors of hydrocarbon feedstocks in that it promotes catalytic deactivation reactions, for example by coking, thus preventing the continued operation of the reactor. . Indeed, when the cake of catalyst becomes too thick along the pipe, it is then necessary to reduce the load flow to be treated or even completely stop the unit for unclogging said pipe.
