    摘要: The invention concerns a process for moving bed regeneration of a reforming or aromatic hydrocarbon production catalyst. The catalyst includes a support, at least one noble metal and at least one halogen. The process includes a combustion step in which the catalyst is treated in at least two successive combustion zones. Also, the process includes each combustion zone separated from adjacent combustion zones allowing catalyst to pass and preventing passage of gas, at least one oxygen-containing gas introduced into each zone and produced gases extracted from each zone, and the severity of the operating conditions in each zone increasing in the direction of catalyst flow. Advantageously, the combustion step ends in a zone for monitoring and controlling combustion completion characterized by a low or zero oxygen consumption.

    摘要: 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.

    摘要: An apparatus for regeneration a reforming or aromatic compound production catalyst comprises a first combustion zone wherein the first combustion zone receives catalyst and an oxygen-containing gas; a successive second combustion zone; and a conduit communicating the first and second combustion zones for transferring catalysts from the first combustion zone to the second combustion zone. The first combustion zone is isolated from the second combustion zone to prevent passage of oxygen-containing gas from the first combustion zone to the second combustion zone and the severity of the operating conditions increases from the first combustion zone to the second combustion zone.
