Abstract
A vessel for regenerating used catalyst comprising at least one combustion zone provided with at least two walls () between which the catalyst circulates as a moving bed, and provided with at least one conduit () for introducing at least one oxygen-containing gas entering the moving bed via one of the walls and leaving via another wall, characterized in that it also comprises a zone (FC) for monitoring and controlling the end of combustion located after the end of the flame front of the last combustion zone (Z), provided with a conduit () for introducing an oxygen-containing monitoring and control gas and at least one means for measuring the temperature and/or the oxygen content in the gas and/or the catalyst leaving the monitoring and control zone. A separator () is located between the monitoring and control zone and the last combustion zone for preventing the passage of gas while allowing for the passage of the catalyst.
