This patent describes a process for the conversion of hydrocarbon feedstock. It comprises maintaining a reaction zone containing a fluidized bed of finely divided inert particles and finely divided zeolite catalyst particles at conversion conditions; charging hydrocarbon feedstock to the reaction zone; withdrawing a mixture of deactivated zeolite catalyst and inert particles from the reaction zone; stripping entrained hydrocarbon from the mixture; charging the stripped mixture of zeolite catalyst and inert particles to a regeneration zone; flowing a hydrogen-deficient supplemental fuel comprising coke or charcoal into the regeneration zone to minimize evolution of water upon combustion within the regeneration zone; introducing a sufficient amount of oxygen into the regeneration zone to regenerate the deactivated zeolite catalyst and to burn the hydrogen-deficient supplemental fuel; withdrawing regenerated zeolite catalyst and inert particles from the regeneration zone; and mixing the regenerated zeolite catalyst and the inert particles with the hydrocarbon feedstock.
