ABSTRACT:
In a method and apparatus for improving the flow of catalyst particles from a riser conversion zone to a separator in a fluidized catalytic cracking (FCC) unit, the exit of the riser conversion zone is equipped with a deflector mounted so as to redirect catalyst particle and gas suspension movement toward a separator inlet, thus preventing rebound back into the riser conversion zone. The catalyst deflector can be combined with one or more of a short contact time stripper, a stripper mount in or adjacent the exhaust barrel of a separator, and/or a catalyst seal pot, all serving to reduce "residence" time of hydrocarbons with catalyst particles.
