ABSTRACT OF THE DISCLOSURE An apparatus and method are provided to remove the heat during the regeneration of catalyst particles. A regenerator comprises a regeneration zone and a cooling zone having disposed therein a steam coil. The two zones are separated by a vertical partition open at both ends. Colder catalysts from the cooling zone flows into the regeneration zone and visa versa due to differences in densities of the fluidized particles in each zone. The flow of aeration steam to the cooling zone is controlled by a valve.
