ABSTRACT:
The present invention relates to a device with a rotating fluidized bed in one or a succession of cylindrical chambers, in which injectors (12), distributed around the fixed circular wall (2) of said cylindrical chamber(s), inject along this wall, in successive layers, one or more fluids (13), which entrain the solid particles (17), passing through this/these chamber(s), in a movement of rapid rotation whereof the centrifugal force concentrates these particles along this wall, thereby forming a fluidized bed rotating around a central duct or a plurality of central ducts (3), through which the fluids are removed. The present invention further relates to a method of catalytic polymerization, drying or other treatments of solid particles in suspension in a rotating fluidized bed or of catalytic conversion of fluids passing through said rotating fluidized bed using a device according to the present invention.
