Abstract: A nozzle is provided for use in discharging a controlled stream of fluid into a reactor tube of a catalyst unloading apparatus for removing non-packed, non-bridging, and packed bridging flowable catalyst and bead material from within the reactor tube. The nozzle has a main channel running medially along its length for entry and exit of the controlled fluid, and a plurality of unevenly spaced smaller fluid discharge openings positioned around the circumference of the nozzle at such an angle to the central axis of the nozzle so as to discharge some of the controlled fluid in an upward and sideward thrusting manner, such that a sideward and downward thrust is exerted against the nozzle, thereby forcing the nozzle to position itself in a downward manner against the side of the reactor tube. This action allows both the catalyst and the bead material to be removed in one continuous operation.
