What are the Common Methods of Active Regeneration?
Several methods are employed for active regeneration, depending on the type of catalyst and the nature of the contaminants:
1. Thermal Regeneration: Involves heating the catalyst to high temperatures to burn off carbonaceous deposits and other impurities. 2. Chemical Regeneration: Uses chemicals such as hydrogen, oxygen, or solvents to react with and remove the contaminants. 3. Steam Regeneration: Involves the use of steam to remove contaminants, particularly effective for catalysts used in _hydrocarbon processing_. 4. Oxidative Regeneration: Utilizes oxygen or air to oxidize and remove carbon deposits from the catalyst surface.
