At least one movable nozzle (14) is mounted in an opening (18) in the wall of a fluidized bed reactor (22). Solid feed materials (62) in granular form are conveyed to the nozzle (14) and injected into the reactor (22). By changing the direction of the solids injection flow stream, the mixing, residence, and reaction characteristics of the reactor (22) may be controlled. The nozzle (14) is elongated and arranged so as to tilt on a horizontal axis (58), and may inject fresh material or recycled material previously removed from the bed reaction zone (34).
