In many cases, degraded catalysts can be regenerated to restore their activity. Regeneration techniques include thermal treatment, chemical cleaning, and mechanical reactivation. Thermal treatment involves heating the catalyst to high temperatures to remove adsorbed species. Chemical cleaning uses solvents or reactive gases to remove poisons or deposits. Mechanical reactivation involves physically removing contaminants through methods such as grinding or ultrasonic cleaning. However, repeated regeneration may only be a temporary solution, as the catalyst may continue to degrade over time.
