The present disclosure provides a process for high conversion residue cracking in a circulating fluidized bed reactor while integrating it with the dehydration of ethanol. More particularly, the present disclosure relates to an integrated circulating fluidized bed process for the simultaneous dehydration of ethanol and cracking of a hydrocarbon feedstock. By integrating the cracking reactor with ethanol dehydration reactor, more conradson carbon residue feedstock can be processed in cracking reactor while limiting the coke combustor temperature.
