The present invention discloses a process optimizing the yield of 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 separation unit stream and a second separation unit stream, the first separation unit stream comprising Cparaffins, and the second separation unit stream comprising Colefins, wherein the second separation unit stream is passed to a second catalytic reactor and the first separation unit stream is removed from the process.

Process and apparatus for improving propylene yield from a fluid catalytic cracking process

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.
