Abstract
The present invention discloses a process optimizing the yield of ethylene and propylene from a fluid catalytic cracking unit. The method combines a first catalytic reactor, a fractionation zone, a separation unit and a second catalytic reactor. The separation unit produces a first separate stream comprising Colefins and a second separate stream comprising Colefins. The separate streams may be combined and are passed to a second catalytic reactor for additional conversion to ethylene and propylene.
