The invention concerns a process for regenerating a catalyst for the production of aromatic hydrocarbons or for reforming, comprising a step for combustion in a zone A comprising at least 2 beds Aand A, a step for oxychlorination in a zone B, and a step for calcining in a zone C. A portion of the effluent gas from the oxychlorination zone is recycled via at least one scrubbing section D to the inlet to beds Aand A. Further, a portion of the effluent gas from zone B is recycled to the combustion bed A, passing via a blower but without passing via said scrubbing section D, and a portion is recycled to the inlet to zone B, passing via said blower but not via said scrubbing section. The invention also concerns the vessel in which said process is carried out.
