摘要: The invention concerns a process for regenerating a catalyst for the production of aromatic hydrocarbons or for reforming. Said process comprises a step for combustion in a zone A comprising at least 2 beds A1 and A2, 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 A1 and A2. Further, a portion of the effluent gas from zone B is recycled, passing via a blower and without passing via said scrubbing section D, to the combustion bed A2.
