There are several methods employed for catalyst cleaning, including: - Thermal treatment: Heating the catalyst to high temperatures to burn off organic contaminants. - Chemical treatment: Using acids, bases, or solvents to dissolve and remove impurities. - Physical methods: Techniques like ultrasonication to dislodge contaminants from the catalyst surface. Each method has its own advantages and limitations depending on the nature of the catalyst and the types of contaminants involved.
