摘要： A system for processing a selected feedstock using a catalyst includes a reactor, a catalyst recovery system, and a conduit. The reactor receives the catalyst and the selected feedstock. A reaction between the selected feedstock and the catalyst generates a spent catalyst. The catalyst recovery system processes the spent catalyst. The conduit connects the reactor to the catalyst recovery system and has a lateral section. The spent catalyst flows from the reactor through a flow space defined by an inner wall of the lateral section to the catalyst recovery system. The system also includes a fluidizer positioned at the lateral section. The fluidizer includes at least one nozzle. The at least one nozzle is completely inside the flow space. The at least one nozzle forms and directs a jet of a fluidizing agent into the spent catalyst in the lateral section.
