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.

An improved hydrocracking process of hydrocarbon charges, in two stages with an intermediate separation, in which the second-stage of hydrocracking is carried out in the presence of an added nitrogen content which is greater than 150 ppm by weight, preferably about 500 ppm by weight, and preferably in the presence of a Y zeolite catalyst, produces high yields of middle distillate.

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.
