Abstract
The invention concerns a process for regenerating a catalyst in a fixed or moving bed, for example a catalyst for reforming or for aromatic compound production, including a step for monitoring and controlling combustion completion which is carried out after the catalyst has undergone all of the combustion steps of the process. The monitoring and control step is carried out by injecting an oxygen-containing gas into the zone where monitoring and control takes place, the monitoring and control step being carried out under conditions which are more severe than those in the combustion steps. The monitoring and control step is carried out with an oxygen consumption of less than 10%. The temperature advantageously remains substantially constant. The vessel for carrying out the invention is also claimed.
