Abstract:
1. A process for regenerating a catalyst for the production of aromatic hydrocarbons or for reforming, comprising: a) combustion in a combustion zone A comprising at least two combustion beds, a first bed A b) 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; c) 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 first bed A effluent gas from first bed A the gas supplying the calcining zone C moves freely towards the oxychlorination zone B; at least one makeup of oxygen-containing gas is made to the inlet to the calcining zone; a portion of effluent gas from the oxychlorination zone is recycled via at least one scrubbing section D towards the inlet to first combustion bed A at least a portion of effluent gas from the oxychlorination zone is recycled, passing via a blower, without passing through said scrubbing section D, directly to the second combustion bed A a portion of effluent gas from second combustion bed A
