Beschreibung
Zusammenfassung:	Regenerator for catalytic cracking unit comprising a first part occupied by a dense fluidized bed of catalyst and a second part positioned above the first part and occupied by a fluidized bed of low solid particles density, the said second part comprising one internal device covering, by projection onto the plane of the cross section of the said vessel of the regenerator, at least 80% of the said cross section, the said regenerator being equipped with at least one cyclone for separating gases/solids in the mixture derived from the low-density bed, the said cyclone being placed outside the vessel of the regenerator.
