Abstract:
An apparatus for contacting fluidized particles with an at least partially liquid feedstock, said apparatus comprising:a) an elongated transport conduit having an upstream and a downstream end; b) means for adding fluidized particles to the upstream end; c) two opposing parallel chord members located transverse to the primary axis of the conduit and separating the upstream and downstream ends of the transport conduit, the chord members extending inwardly from the inner sidewall of the transport conduit and across the transport conduit and defining a restricted opening in the center of the transport conduit; d) a feed injection line at or adjacent to and parallel with each chord member for injecting feed into the conduit from two sides over a length substantially equal to a length of the chord members; and e) means for recovering a mixture of catalyst and feed from the downstream end of the conduit.
