    Abstract: A unitary, multiple-stage reaction system for countercurrently contacting a fluid reactant stream with catalyst particles movable through the system via gravity-flow. The reaction zones, or stages, are vertically stacked in a single chamber wherein catalyst particles flow from one annular-form bed to the next lower annular-form bed. A first portion of the hydrocarbonaceous charge stock flows downwardly into the lowermost reaction zone, laterally (outward to inward flow) through the annular-form catalyst bed into a center reactant conduit, is admixed with the second portion of the charge stock, flows upwardly through the reactant conduit into the next upper zone and laterally (inward to outward flow) through the annular-form catalyst bed. A preferred embodiment involves three reaction zones within the reaction chamber, with heat-exchange provisions between the middle and upper zones.
