Several methods are used to regenerate catalysts, depending on the type of deactivation:
- Thermal Regeneration: Heating the catalyst to high temperatures to remove adsorbed species or to restore the crystalline structure. - Chemical Regeneration: Using chemical agents to remove poisons or to re-disperse active sites. - Oxidative Regeneration: Employing oxygen or other oxidizing agents to burn off coking deposits. - Reductive Regeneration: Using hydrogen or other reducing agents to restore the oxidation state of the catalyst.
