Abstract: Process for regeneration of a catalytic moving bed in which the catalyst successively passes through at least one combustion zone A, at least one halogenation zone B, and at least one calcination zone C, whereby this process operates in a partial-regeneration-mode, the partially coked catalyst that is obtained from the last combustion zone passes into the halogenation zone in which the amount of halogen and the amount of oxygen are essentially zero--the valves of tubes (19) and (20) are then virtually closed--and the catalyst then passes through the calcination zone in which the amount of oxygen is essentially zero--the valve of tube (11) is then virtually closed.
