ABSTRACT:
Process and apparatus suitable for the regeneration of catalytic cracking catalyst particles and for the heating and partial conversion of coke particles from a coking process are described. The particles are heated in two successive zones, for example formed by two fluidized beds, conditions being controlled so that (1) only partial regeneration of catalyst particles or conversion of coke particles occurs in the first zone, and (2) there is no major evolution of heat from either zone.
