Several strategies can be employed to extend the lifetime of catalysts:
1. Regeneration: Periodic regeneration processes such as oxidative or reductive treatments can restore the activity of deactivated catalysts. 2. Improved Catalyst Design: Using more robust materials or designing catalysts with higher resistance to sintering and poisoning can enhance longevity. 3. Optimizing Reaction Conditions: Fine-tuning operating conditions such as temperature, pressure, and feed composition can minimize deactivation. 4. Protective Coatings: Applying protective layers can prevent direct exposure of the active sites to poisons and other deactivating agents. 5. Additives: Incorporating additives that act as scavengers for poisons can prolong catalyst life.
