ABSTRACT:
This invention provides a process for limiting the loss of catalyst particles through olefin product streams and regenerator flue gas streams exiting the reaction system. In particular, this invention provides for removing catalyst particles from the reactor using a water stream and from the regenerator using a two step separation process. The two step process involves the use of a catalyst fine separation unit.
