摘要
对目前燃煤烟气中气态Hg0污染物吸附剂进行了分类研究,重点总结了碳基吸附剂、层状矿物类吸附剂、磁性吸附剂等3类吸附剂的特点,对气态Hg0的吸附效果及吸附机理进行了深入探讨.通过分析比较,提出了研制高效吸附剂的主要途径,并展望了气态Hg0吸附剂的发展趋势.
One of main ways to control the mercury pollutants in air is removing gas-phase Hg0 from coal-fired flue gas by solid sorbents.The current solid sorbents for removal of gas-phase Hg0 in coal-fired flue gas have been classified and investigated in this paper,which chiefly summarized the characteristics of carbon-based sorbents,layered clay-based sorbents and magnetic sorbents,adsorption efficiency and mechanisms of some solid sorbents to gas-phase Hg0 in coal-fired flue gas.Based on the comparison and analysis of experimental results,the main approach to prepare efficient sorbents was proposed in this review.
