摘　　要：现行轻型汽车污染物排放限值及测量方法(中国第六阶段)(GB 18352.6—2016)要求汽油中的硫质量分数不能超过10μg/g,因此汽油的深度脱硫技术将持续受到关注。反应吸附脱硫技术具有脱硫率高、辛烷值损失低的优点,是目前用于汽油脱硫的主要手段之一。了解和认识反应吸附脱硫催化剂的组成和各组分之间的相互作用机理,对于提高催化剂活性和稳定性,推进反应吸附脱硫技术发展具有重要意义。详细介绍了反应吸附脱硫催化剂中脱硫活性金属组分、储硫组分、以及载体3种组分的功能与研究进展,分析了每种组分优化对脱硫催化剂活性的影响,讨论了反应吸附脱硫过程中的机理问题,以期为未来反应吸附脱硫催化剂的研发提供参考。The current limits and measurement methods for pollutant emissions from light-duty vehicles(CHINA 6)(GB 18352.6—2016)require that the sulfur mass fraction of gasoline should not exceed 10μg/g,so the deep desulfurization of gasoline will continue to receive attention.The reaction adsorption desulfurization technology has the advantages of high desulphurization rate and low octane loss,which is one of the main means for gasoline desulfurization at present.Understanding and recognizing the composition of reactive adsorption desulfurization catalysts and the interaction mechanism among components are of great significance for improving catalyst activity and stability and advancing the development of the reaction adsorption desulfurization technology.The functions and research progress of three components such as desulfurization active metal component,sulfur storage component,and carrier in reactive adsorption desulfurization catalysts are described in detail,the effect of optimization of each component on the activity of desulfurization catalysts is analyzed,and the mechanical aspects of reactive adsorption desulfurization process are discussed.These efforts aim to provide a reference for the future research and development of reactive adsorption desulfurization catalysts.
