A process for regenerating a catalyst for the production of aromatic hydrocarbons or for reforming, comprising the following steps: • a step a) for combustion in a combustion zone A comprising at least two combustion beds A1 and A2 in series; • a step b) for oxychlorination in an oxychlorination zone B comprising at least one oxychlorination bed, said oxychlorination zone B being supplied with at least one chlorinating agent, at least with water or water precursors and at least with an oxygen-containing gas; the combustion zone and the oxychloration zone being separated so as to prevent the gas deriving from the combustion and the gas deriving from the oxychloration from mixing, • a step c) for calcining in a calcining zone C comprising at least one calcining bed supplied with a gas comprising at least a makeup of dry air; in which: • said catalyst comprises a support, chlorine and at least one noble metal and moves in series in beds A1 then A2, then in the oxychlorination zone B then in the calcining zone C; • the effluent gas from bed A1 is sent to bed A2; • the gas supplying the calcining zone C moves freely to the oxychlorination zone B; • a makeup of oxygen-containing gas is made at least to the inlet to the calcining zone; • the effluent gas from the oxychlorination zone is recycled via at least one scrubbing section D towards the inlet to combustion beds A1 and A2; • the effluent gas from the oxychlorination zone is recycled, passing via a blower, without passing through said scrubbing section D, at least in part to the combustion bed A2 and at least in part to the inlet of the oxychlorination zone B; • the effluent gas from combustion bed A2 is recycled via at least said scrubbing section D to the inlet of beds A1 and A2. • a step a) for combustion in a combustion zone A comprising at least two combustion beds A1 and A2 in series; • a step b) for oxychlorination in an oxychlorination zone B comprising at least one oxychlorination bed, said oxychlorination zone B being supplied with at least one chlorinating agent, at least with water or water precursors and at least with an oxygen-containing gas; the combustion zone and the oxychloration zone being separated so as to prevent the gas deriving from the combustion and the gas deriving from the oxychloration from mixing, • a step c) for calcining in a calcining zone C comprising at least one calcining bed supplied with a gas comprising at least a makeup of dry air; • said catalyst comprises a support, chlorine and at least one noble metal and moves in series in beds A1 then A2, then in the oxychlorination zone B then in the calcining zone C; • the effluent gas from bed A1 is sent to bed A2; • the gas supplying the calcining zone C moves freely to the oxychlorination zone B; • a makeup of oxygen-containing gas is made at least to the inlet to the calcining zone; • the effluent gas from the oxychlorination zone is recycled via at least one scrubbing section D towards the inlet to combustion beds A1 and A2; • the effluent gas from the oxychlorination zone is recycled, passing via a blower, without passing through said scrubbing section D, at least in part to the combustion bed A2 and at least in part to the inlet of the oxychlorination zone B; • the effluent gas from combustion bed A2 is recycled via at least said scrubbing section D to the inlet of beds A1 and A2.
