ABSTRACT:
An improved fluidized catalytic cracking-catalyst regeneration process for catalytically cracking heavy hydrocarbon feedstocks is provided which comprises first and second, relatively lower and higher temperature, catalyst regeneration zones, wherein CO-rich effluent flue gas from the first regeneration zone is combusted in a CO-incinerator/combustor means to substantially convert all CO present therein to CO.sub.2. The effluent gas from the CO-incinerator/combustor is then combined with the effluent flue gas from the second regeneration zone, with the combined streams thereafter being sent to an expansion turbine-compressor means to recover the work energy therefrom and to provide at least all the compressed air requirements of the first and second regeneration zones, and preferably in addition the compressed air requirements of the CO-incinerator/combustor means.
