Abstract

Developing an efficient remanufacturing process that mitigates severe failure in particulate metal catalysts (PMCs) is necessary to reduce environmental pollution (e.g., CO₂ emission) and manufacturing costs. In this study, a PMC remanufacturing process was developed by classifying the failures exhibited by a used PMC into four levels, followed by determining the feasibility of remanufacturing the PMC. The developed remanufacturing process consisted 11 steps according to the failure levels of the used PMC. The performance of a new PMC and that of the PMC remanufactured by our proposed method were evaluated and compared. PMC remanufacturing is an eco-friendly technology that involves less production steps, reduces raw-material consumption, reduces environmental pollution, and aids in resource saving.
