ABSTRACT:
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.
