Abstract: Catalytic reactor (10) with radial flow of a hydrocarbon feedstock to be treated comprising: a reaction zone (13) enclosed in a substantially cylindrical outer shell (14) that is in the form of at least one catalytic module (15) extending along the vertical axis (AX), an annular zone (30) located at the same level as said catalytic module (15), outside of the reaction zone (13), said catalytic reactor being characterized in that it comprises an empty space (27) located between two side walls (23, 24) of at least one catalytic module (15), located outside of the reaction zone (13) and opening onto said annular zone (30), said empty space (27) comprising at least one solid net (26) extending along the vertical axis (AX) and positioned adjacent to the collecting means (29).

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.
