Abstract
A catalytic reactor including a chamber (1) and separation means (2) arranged inside the chamber (1), said separation means defining at least one reaction area (3) and at least one regeneration area (4), the reaction area (3) being supplied with a reaction flow (15, 16) and connected, at the outlet thereof, to a first gas tapping device (13), the regeneration area (4) being supplied with a regeneration flow (17) and connected, at the outlet thereof, to a second gas tapping device (10), the reactor being suitable for including a fluidized bed of catalyst particles (5) in the reaction area (3), the separation means (2) enabling the catalyst particles to pass from the reaction area (3) to the regeneration area (4), and the reactor making it possible to move catalyst particles into the regeneration area (4) so as to enable the return thereof to the reaction area (3).
