Catalyst longevity is crucial in controlling operating costs. A longer-lasting catalyst reduces the frequency of replacement, thereby lowering costs associated with procurement, installation, and downtime. Factors affecting catalyst longevity include:
- Deactivation: Catalysts can deactivate due to coking, poisoning, sintering, or fouling. - Regeneration: Some catalysts can be regenerated, restoring their activity and extending their life. - Durability: The physical and chemical stability of a catalyst under operating conditions determines its lifespan.
