Abstract
A method for disengaging catalyst particulates from the effluent of a riser tube in the operation of a FCC unit. The catalyst component of the resultant ascending fluid stream is propelled from the riser tube into the catalyst disengaging or collection chamber by virtue of the inertial momentum associated therewith. The vaporous hydrocarbon conversion products containing only residual entrained amounts of catalyst, being passively restrained from entering the disengaging chamber, are simultaneously diverted to a fractionation unit via a cyclonic separator.
