The toxic mercury has drawn worldwide attention

especially China's coal-dominated energy consumption structure leads to serious mercury pollution.It is necessary to strengthen the control of mercury.The sources

hazards and migration mechanism of mercury during the combustion were briefly introduced.Moreover

the research development of mercury control technology at home and abroad was reviewed

including the mercury removal before

during and after combustion

among which the post-combustion control technology was focused.The carbon-based sorbents for mercury and non-carbon-based materials were also presented.The mercury removal characteristics and main research findings of carbon-based sorbents(modified by halogen

sulfur

metal and metal oxides)

fly ash

and four non-carbon-based mercury removal materials(such as mineral adsorbents

metal and metal oxides

new renewable magnetic zeolite and nano mercury removal material)were summarized.Finally

each mercury control technology was compared

and the existing problems were discussed.
