Abstract A side by side hydrocarbon conversion-two staged stacked catalyst regeneration arrangement is provided wherein the first stage of catalyst regeneration is temperature restricted to achieve incomplete removal of carbon deposits and a second higher temperature regeneration is accomplished in an upflowing catalyst contact system under conditions to accomplish removal of residual carbon on the catalyst and produce a CO2 rich flue gas. A special external cyclone separator arrangement may be attached to either of the second stage regeneration operationor the riser hydrocarbon conversion operation to effect separation of catalyst particles from gasiform material.
