燃煤烟气中单质汞脱除技术研究进展

Advances in removal of elemental mercury from coal-fired flue gas

综述了各种脱汞材料及改性技术研究现状,基于现有脱汞材料的优缺点及发展空间,提出了一体化吸附-催化材料脱除单质汞的结构设计理念,将脱汞材料的吸附性与催化性耦合起来,实现高效快速吸附单质汞的同时将其完全氧化脱除,为今后烟气脱汞技术设计提供新的思路。

The research status of various mercury removal materials and corresponding modification technologies are reviewed.Based on the advantages and disadvantages of the existing mercury-removing materials and development space,the structure design idea for an integrated adsorption-catalytic material for removing elemental mercury is proposed,which couples the adsorption and catalytic properties of mercury-removing materials and therefore realizes that elemental mercury is efficiently and fast adsorbed,and is completely oxidized and removed simultaneously.This method provides a new idea for designing a coal-fired flue gas mercury-removing technology.
