Abstract: A method of disposing of a mixture of oxidizable catalyst material and inert support media. The method comprises introducing inert gas into an enclosure; introducing the mixture into the enclosure; separating the oxidizable catalyst material and the inert support media within the enclosure; maintaining an inert gas environment around the oxidizable catalyst material during separating; exporting the separated inert support media from the enclosure; and grinding the separated oxidizable catalyst material into a powder for disposal as hazardous waste via incineration.

Abstract: A system for segregating a mixture of oxidizable catalyst material and inert support media. The system comprises an enclosure configured to contain inert gas. The enclosure includes a plurality of stacked screens disposed therein. The stacked screens include openings that decrease in size from a top of the stack to a bottom of the stack. The enclosure also includes an inlet to deliver the mixture to an uppermost stacked screen and outlets to direct the separated support media and catalyst material to a location outside the enclosure.

Abstract: A method for disposing of a mixture of oxidizable catalyst material and inert support media. The method comprises introducing inert gas into an enclosure. The enclosure contains a plurality of stacked screens, the stacked screens have openings that decrease in size from a top of the stack to a bottom of the stack. The method also comprises introducing the mixture to an uppermost one of the plurality of stacked screens; moving the plurality of stacked screens to cause the oxidizable catalyst material to separate from and migrate to a location beneath the inert support media; conveying the separated inert support media to a location outside the enclosure for disposal as non-hazardous waste; and conveying the separated oxidizable catalyst material to a location outside the enclosure for at least one of reclamation, or thermal destruction.
