摘　　要：对褐煤半焦基吸附材料的表面物理化学性质、改性技术及机理进行了探讨,介绍了半焦作为吸附材料在烟气脱硫、脱硝等领域的应用现状,重点总结了烟气中气态Hg0污染物在半焦表面的吸附特性及机理。通过分析比较,指出了以廉价褐煤为原料制备高性能吸附材料的主要途径,并展望了半焦吸附剂在烟气净化领域的发展趋势。The paper discussed the surface physicochemical properties,modification technology and mechanism of the lignite semi-coke sorbents, introduced the application status of semi-coke sorbents in the field of desulfurization and denitration,and summarized the adsorption characteristic as well as adsorption mechanism of gaseous-phase Hg＂ by semi-coke in the flue gas. By analysis and contrast,the primary way to prepare high-performance sorbents based on lignite semi-coke was put forward and the development of semi-coke sorbents in the field of flue gas cleaning was proposed.
