Claim:
1. A moving bed catalyst regenerator ( 1 ) comprising a vessel ( 2 ) extending in a vertical direction, said vessel being divided into at least two regeneration zones extending along the vertical height of said vessel, in which particles of catalyst move under gravity, the regenerator being configured such that each regeneration zone is capable of separately regenerating a different composition of catalyst and in which each regeneration zone comprises, in succession and in the order in which the catalysts move: a) a combustion section (CO); b) an oxychlorination section (O) disposed below the combustion section and comprising means for bringing catalyst from the combustion section (CO) to the oxychlorination section (O); and c) a calcining section (CA) disposed below the oxychlorination section.
