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. L'invention concerne un procédé de traitement catalytique d'une charge hydrocarbonée avec régénération en continu du catalyseur, procédé dans lequel on fait successivement circuler ladite charge dans une pluralité de zones réactionnelles en série (R1,R2,R3,R4), le catalyseur circulant en lit mobile successivement dans la pluralité des zones réactionnelles en s'écoulant de l'extrémité amont à l'extrémité aval de chacune des zones réactionnelles et étant transporté par une phase gazeuse convoyeuse g1 depuis l'extrémité aval d'une zone réactionnelle à l'extrémité amont de la zone réactionnelle suivante, caractérisé en ce que ladite phase gazeuse convoyeuse g1 présente une densité supérieure ou égale à 1 kg/m3.
