Why do precious metal particle catalysts become deactivated?


Before regenerating deactivated precious metal particle catalysts, it is necessary to study and analyze the reasons for their deactivation. By testing various physicochemical properties of the deactivated catalyst samples (including component content, specific surface area, porosity, pore size distribution, crystal structure, strength, activity, etc.), the intrinsic reasons for the deactivation of the precious metal particle catalysts can be confirmed, providing a basis for catalyst regeneration.
