The invention concerns a device for injecting successive layers of fluid in a circulating fluidized bed and a method of catalytic polymerization, drying and or other treatments of solid particles or of catalytic transformation of fluids, wherein a series of injectors (12) distributed around a stationary circular wall (2) of a circular reaction chamber, inject along said wall successive layers of one or more fluids (13) which drive the solid particles (17), passing through said chamber, in a fast rotational movement whereof the centrifugal force concentrates said particles along said wall, thereby forming a fluidized bed circulating about a central chute (3), through which the fluids are evacuated.
Dispositif d'injection de fluide en couches successives dans un lit fluidifié rotatif et procédé de polymérisation catalytique, de séchage ou d'autres traitements de particules solides ou de transformation catalytique de fluides, où une succession d'injecteurs (12) répartis autour de la paroi circulaire (2) fixe d'une chambre circulaire de réaction, injectent le long de cette paroi, en couches successives, un ou des fluides (13), qui entraînent les particules solides (17), traversant cette chambre, dans un mouvement de rotation rapide dont la force centrifuge concentre ces particules le long de cette paroi, for mant ainsi un ht fluidifié tournant autour d'une cheminée centrale (3), par où les fluides sont évacués.
