Catalyst Circularity
Design, recover and remanufacture catalyst systems with material loops in mind.
Industrial note: catalyst performance depends on the specific chemistry, reactor, feed and approved process conditions. This site explains system concepts rather than operating recipes.
What this topic covers
Design, recover and remanufacture catalyst systems with material loops in mind.
Core catalyst ideas
Circularity begins before end of life through material identification and recoverable design.
Manufacturing scrap and spent catalysts can follow different recovery routes.
Metal accounting helps quantify how much platinum actually returns to productive use.
System tradeoffs
Representative sampling and assay are critical to metal accounting because spent catalyst is often heterogeneous.
Performance evidence
Recycling reduces primary-material demand but still involves collection, processing losses and energy.
Lifecycle perspective
Extraction and refining methods are hazardous industrial operations and are outside this site's procedural scope.
