摘要
吸附剂喷入技术是去除燃煤烟气中元素态Hg0的有效方法。详细介绍了各种新型脱汞吸附剂的研究状况,主要包括新型碳基吸附剂、矿物类吸附剂、钙基吸附剂以及金属、金属氧化物吸附剂的制备方法、吸附性能及脱汞机理,并将各种脱汞吸附剂的优缺点做了对比。展望了燃煤烟气脱汞吸附剂研究的发展趋势。
The adsorption technology is a cost-effective method for removing mercury from coal-fired flue gas. The research progress of new mercury removal sorbents was summarized involving the preparation method, absorption efficiency and mechanisms of the new carbon based absorbents, calcium based absorbents, mineral absorbents, metal and metal oxides absorbents. Besides, the shortages and advantages of the abovesorhents used in the mercury removal in coal fired flue gas were contrasted. Finally the dEvelopmEnt of mercury removal sorbents for the future studies was proposed.
