In view of the high cost and short life cycle of S-ZORB gasoline desulfurization filter, we have developed a special cleaning and recycling process. With our self-developed cleaning fluid, we can effectively clean the oil and adsorbent particles in the internal structure of the filter. After cleaning and regeneration, the filter can restore more than 95% of the function, thus reducing production costs. The unique cleaning and regeneration process does not cause any side effects on the filter element. This cleaning regeneration method can also be used to regenerate other types of sintered metal powder cartridges.
