Abstract:

Bioregeneration, a rising regeneration method for adsorbents in recent years, has good prospects in research and industrial applications.The bioregeneration processes and mechanisms for commonly used adsorbents, such as activated carbon and zeolite, are summarized.Current essential bioregeneration processes, such as offline, online and fixed-bed reactor bioregenerations, are reviewed.The bioregeneration for the adsorbents used in diesel desulfurization is discussed in detail.Meanwhile, the problems to be solved are presented, and the prospect research works in future are proposed.
