A two stage (22, 34) regeneration operation under sequential endothermic and exothermic temperature restricted conditions to remove high levels of carbonaceous material contributed by feeds of Conradson carbon content in the range of 2 to 20 is discussed. Initial removal of carbonaceous material of at least 40 percent is accomplished primarily with steam (25) and CO2 followed by removal of residual carbonaceous material with oxygen under CO2 flue gas producing conditions subsequentially employed in said endothermic operation with steam.
