What should do if catalyst is deactivated?

Описание: Catalyst deactivation should be treated according to the principle of "diagnosis first, then treatment." The first priority is to accurately diagnose the root cause of deactivation. Common causes include carbon deposition, poisoning, and sintering. For reversible deactivation, such as carbon deposition, activity can be restored through "burn-off regeneration" with strict control of temperature and oxygen concentration. If the catalyst is permanently deactivated due to poisoning or severe sintering, it must be replaced. The fundamental solution lies in prevention, including rigorous raw material purification and optimized operating conditions to avoid overheating. This maximizes catalyst life and ensures stable, economical, and long-term operation.
