Abstract
A vessel for regenerating a catalyst for reforming or for aromatic compound production comprising a support, at least one noble metal and chlorine, the catalyst being in the form of a moving bed, said vessel comprising at least one combustion zone (A) provided with at least one conduit (9) for introducing oxygen gas and at least one conduit (5) for evacuating gasses from the combustion step, at least one oxychlorination zone (B) and at least one calcining zone (C) provided with at least one conduit (18) for introducing an oxygen-containing gas, said vessel also comprising at least one conduit (1) for introducing catalyst into the vessel, at least one conduit (3) for introducing catalyst from the combustion zone into the following oxychlorination zone (B), and at least one conduit (21) for evacuating gases from the oxychlorination zone comprising at least one means (20) for introducing least one chlorinating agent and at least one means (19) for introducing water and at least one means (17) for introducing an oxygen containing gas.
