Abstract:
The present invention concerns 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, 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); c) a calcining section (CA) disposed below the oxychlorination section; characterized in that the regeneration zones are separated from each other by a separation means which is impermeable to catalysts and to gases in a manner such that the catalysts of each of the zones are capable of being regenerated under different operating conditions.
