Abstract
In a reactant-fluid catalyst suspension system, an arrangement of apparatus is provided contiguous with a riser discharge which centrifugally initially separates the suspension into a solids phase and a gasiform material phase prior to discharge from the riser. The catalyst may be further stripped if desired in equipment above and about the riser discharge. The arrangement contributes substantially to the efficiency and economics of the separation of catalyst from gasiform products including products of hydrocarbon conversion and combustion products of catalyst regeneration.
