Abstract
A system and method use a converter and a movable storage silo for receiving, processing, and transporting spent catalysts. The spent catalysts can be utilized in the manufacture of cement instead of being disposed in landfills. A hydraulic sub-system remove dusts from the spent catalyst prior to storage in the silo.
Claims9
A catalyst converter, comprising:
- a tank having an interior;
- a layer of balls within the interior of the tank and configured to retain from above and within the interior spent catalyst and dust resulting from operation of an industrial process;
- and
- a conveyor belt having a portion thereof within and in continuous communication with the interior of the tank, wherein the conveyor belt includes a mesh removably holding the spent catalyst thereon, and
- wherein the conveyor belt is configured to transport the spent catalyst externally to a vacuum suction device for removal of the spent catalyst from upon the conveyor belt.
