Catalyst regeneration involves restoring the catalyst's activity through various methods:
1. Thermal Regeneration: Heating the catalyst to burn off carbon deposits. 2. Chemical Washing: Using solvents or acids to dissolve and remove contaminants. 3. Oxidation-Reduction Cycles: Alternating between oxidizing and reducing atmospheres to remove poisons and regenerate active sites. 4. Steam Treatment: Utilizing steam to clean and rehydrate the catalyst surface.
