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.

Abstract: Method for the simulated moving bed (SMB) separation of a feedstock (F), in which: at least one zone (1, 2, 3, 4) contains fewer than three beds, if the stream (D, E, F, R) delimiting said zone and situated upstream of said zone is injected or withdrawn at the plate Pi via the bypass line Li/i+1, then the stream delimiting said zone and situated downstream of said zone is injected/withdrawn at the plate Pj via the bypass line Lj/j+1, and if the stream delimiting said zone and situated downstream of said zone is injected or withdrawn at the plate Pi via the bypass line Li−1/i, then the stream delimiting said zone and situated upstream of said zone is injected/withdrawn at the plate Pj via the bypass line Lj−1/j.

Abstract: Process for fixed-bed reforming of a hydrocarbon-based feedstock comprising n-paraffinic, naphthenic and aromatic hydrocarbons, at a temperature of between 400 and 700° C., a pressure of between 0.1 and 4 MPa, and a mass flow of feedstock treated per unit mass of catalyst and per hour of between 0.1 and 10 h−1, by bringing said feedstock into contact with a catalyst comprising platinum, a promoter metal selected from the group consisting of rhenium and iridium, a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, and a porous alumina support in the form of an extrudate characterized by a length “l” of between 1 and 10 mm, a section comprising four lobes, the largest diameter “D” of the cross section of said extrudate being between 1 and 3 mm.

Abstract: Method for the simulated moving bed separation of a feedstock (F), in which when a fluid/effluent (feedstock F, desorbent D, extract E, raffinate R) is injected/withdrawn into/from a chosen plate (Pi) using an external bypass line (Li−1/i, Li+1/i) connected to said chosen plate (Pi), the flow rate within the said external bypass line (Li−1/i, Li+1/i) is controlled in such a way that: a major proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the chosen plate (Pi); and a minor proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the adjacent plate (Pi−1, Pi+1) connected to the said external bypass line (Li−1/i, Li+1/i).
