Abstract: 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.

Abstract: A process for conversion of hydrocarbon feedstock into lighter olefins of C2 to C4 carbons, the process comprising of cracking the hydrocarbon feedstock in a reactor in the presence of a catalyst. The catalyst for short contact time catalytic cracking process of heavy hydrocarbons having contact time less than 1 second to produce light olefins of C2 to C4 carbon in the range of 40 to 60 wt % on fresh feed basis in a fluidized bed reactor which is concentric downflow reactor in presence of catalyst consisting of ultra-stable Y zeolite in the range of 5-10 wt %, 4 to 8 wt % of pentasil zeolite, 2.5-5 wt % of bottom selective material, 0.5-2 wt % of rare earth and 75-88 wt % of support material.
