S⁃Zorb reaction adsorption desulfurization technology has become one of the important gasoline deep desulfurization technologies because of its high efficiency desulfurization effect and mild process conditions. S⁃Zorb desulfurization technology was developed by Phillips company and has been widely promoted in China since it was exclusively acquired by Sinopec. However, the composition of its adsorbent has not been fully published. Therefore,the focus of the S⁃Zorb process research is on the localization of the adsorbent at present, and the activity and stability of the desulfurizer are continuously improved through in⁃depth research on the reaction adsorption mechanism. The process development and existing problems of S⁃Zorb reaction adsorption desulfurization technology and the latest progress of research and development of S⁃Zorb reaction adsorption desulfurization agent were reviewed, and the mechanism of reaction adsorption desulfurization was discussed.
