Abstract
A catalyst loading and unloading system for chemical reactors has an extendable catalyst transfer tube that is fed by a catalyst hopper and controlled by a tube displacement mechanism; more particularly, by a winch mechanism. As the reactor chamber fills with catalyst, a lower end of the extendable catalyst transfer tube is displaced upward by the tube displacement mechanism to correspond with the rising height of the catalyst bed within the chamber. The extendable catalyst transfer tube may further be used to vacuum old catalyst out of the reactor chamber.
