Various strategies can be employed to mitigate the loss of active sites:
Use of Promoters: Adding small amounts of promoters can enhance the stability and resistance of the active sites to poisoning and sintering. Optimizing Reaction Conditions: Carefully controlling the reaction conditions such as temperature, pressure, and feed composition can minimize the risk of coking and thermal degradation. Regeneration: Some catalysts can be regenerated through processes such as calcination, which involves heating the catalyst in the presence of air to remove coke and other impurities. Coating Catalysts: Applying protective coatings can help shield the active sites from deactivating agents while still allowing reactant access.
