Abstract: The invention relates to a process for the catalytic treatment of a hydrocarbon feedstock with continuous catalytic regeneration, in which process said feedstock is successively circulated in a plurality of reaction zones in series (R1, R2, R3, R4), the catalyst circulating as a moving bed successively in the plurality of reaction zones and flowing from the upstream end to the downstream end of each of the reaction zones and being transported by a carrier gas phase g1 from the downstream end of one reaction zone to the upstream end of the next reaction zone, characterized in that said carrier gas phase g1 has a density of greater than or equal to 1 kg/m3.
