Abstract: 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.

摘要： S⁃Zorb反应吸附脱硫技术因其高效的脱硫效果、温和的工艺条件已经成为重要的汽油深度脱硫技术之一，S⁃Zorb脱硫技术由Phillips公司开发，自从被中国石化独家收购以来，在国内被广泛推广。但是目前，其吸附剂的组成尚未完全公布，因此S⁃Zorb工艺研究的重点在于吸附剂的国产化，以及通过对反应吸附机理的深入研究来不断提高脱硫剂的活性和稳定性。综述了S⁃Zorb反应吸附脱硫技术的工艺发展、运行中存在的问题以及S⁃Zorb反应吸附剂的研究与开发的最新进展，并对反应吸附脱硫的机理进行了讨论。
