Deactivation can occur due to several factors including sintering, fouling, and poisoning. Proper storage can help mitigate these risks:
- Avoid Sintering: Store catalysts at low temperatures to prevent the agglomeration of particles. - Prevent Fouling: Keep catalysts away from environments with high particulate matter or potential fouling agents. - Minimize Poisoning: Ensure that catalysts are not exposed to poisons such as sulfur, phosphorous, or halides, which can bind to active sites and reduce efficacy.
