ABSTRACT:
A catalyst trough containing multiple guide tubes in registry with the tubes of a multi-tube catalytic reactor is utilized to unload catalysts therefrom with maximum dust containment and maximum catalyst recovery. The catalyst recovery trough contains an outlet collar connected to an outlet line and a positive fastener whereby the trough is fixedly but detachably connected to the tube sheet of the reactor. The guide tubes extend vertically upwardly from the bottom of the trough and are open in the bottom so as to allow the provision of flexible steel rods or "fish tapes", which may or may not be equipped with high-fluid pressure tubes as air-lances for feeding into the tubes of the reactor, which are on center with the guide tubes of the trough. In this manner any catalytic material which is stuck or bridged across the catalytic tubes may be dislodged so as to fall by gravity into the recovery trough and into an outlet line for recovery.
