The method and means of this invention comprises discharging a suspension of solids (inert or catalytic) in gasiform material (whether hydrocarbon vapors, combustion product flue gases, stripping gases or combinations thereof) from a riser contact zone through a plurality of radiating confined passageway emanating from the upper discharge periphery of the riser each of which is in tangential communication at the outer end of the confined passageway with a cylinder open in the bottom end thereof. The cylinder is closed at the top except for a coaxially aligned conduit of smaller diameter extending downwardly through said cylinder with its bottom open end terminating adjacent a lower portion of the inlet of the confined passageway.

In a processing combination of hydrocarbon conversion in the presence of fluidizable solid particle material and regeneration of solid particle material to remove carbonaceous deposits by combustion wherein a riser zone is employed to pass a suspension of solids in gasiform material upwardly through the riser the improvements which comprises, passing a suspension of fluidizable solids in gasiform material radially outward from a riser contact zone by a confined open end passageway communicating with a cylinderical zone open in the bottom on the outer end thereof, said confined passageway communicating tangentially with said cylindrical zone whereby a suspension of solids in gasiform material is separated by centrifugal momentum differential within said cylindrical zone to form a compact centrifugal flowing mass of solids separated from gasiform material collected in a central portion of said cylindrical zone, discharging said compact flowing mass of solids from the open bottom of said cylindrical zone in counter current contact with upwardly flowing stripping gas passing upwardly into the bottom portion of said cylindrical zone and, withdrawing gasiform material upwardly from within said cylindrical zone separated from particle material for recovery as products of the separation combination.
