ABSTRACT:
A multiple stage hydrocarbon conversion system wherein a hydrogen-hydrocarbonaceous feedstock reaction mixture is processed serially through a plurality of reaction zones, each of which contains a particulate catalyst disposed as an annular-form bed movable downwardly through the reaction zone, and wherein said reaction mixture is processed in radial flow through said annular-form bed. Pinning of the catalyst particles within the annular-form bed is substantially obviated by the combined effect of charging only a portion of the total hydrogen to the first reaction zone, charging the balance of the total hydrogen to a subsequent reaction zone, and restricting the effluent flow of at least one reaction zone.
