NiZnO sorbent was selected to achieve desulfurization purpose. Combining with characterization techniques such as X-ray photoelectron spectroscopy and scanning electron microscope, the experimental process was analyzed and discussed. The results showed that NiZnO sorbent could effectively adsorb SO2 to achieve desulfurization purpose. Through AXAFS technology, it was found that the Zn active site in NiZnO sorbent was the main position for adsorbing SO2, while Ni mainly played the role of inhibitor. Therefore, the research in this paper can provide theoretical guidance for the further development of new desulfurization sorbents.Keywords: AXAFS technology; NiZnO sorbent; desulfurization; mechanism
