摘要
简述了目前世界范围内认可度较高的分子尺寸选择、酸碱配位、π络合、S-M配位4种吸附机理。并按上述机理介绍了吸附剂（包括活性炭、分子筛、金属氧化物以及金属有机框架等）的研究进展。提出了吸附剂未来的发展方向是在较低成本的前提下，向更为多元化、综合化和绿色化方向发展，即集多种吸附机理协同作用于同一吸附剂上，以期得到高硫容、高选择性、绿色、经济的吸附剂。
Abstract
This paper describes four adsorption mechanisms with high recognition degree worldwide,including selection by molecular size,acid-base coordination,π-complexation and S-M bonds coordination.The research progresses on corresponding absorbents,including activated carbon,molecular sieves,metal oxides and metal organic frameworks are introduced in detail based on these four mechanisms.Herein,it is proposed that the future research directions for adsorbents will be more diversified,more comprehensive,and greener under the premise of low cost,which means to integrate different adsorption mechanisms on the same adsorbent,and thus a high sulfur capacity and selectivity,green and economically feasible adsorbent will be obtained.
