Abstract
The invention concerns a process for fluidising a catalyst or an adsorbent in a furnace which is fixed but the fluidised bed advances, optionally with rotation, in the presence of another inert solid with a granulometry which is different from that of the catalyst or the adsorbent, in the presence of a fluidisation gas, to carry out either stripping of a catalyst or an adsorbent or regeneration of a catalyst or an adsorbent in the furnace.
