Research status and prospects of coal-fired power plant flue gas mercury removal technology

摘要

As a large coal resource consuming country in my country, the problem of coal-fired flue gas emissions has been paid more attention, and mercury control has become particularly important. This article outlines some of the existing coal-fired power plant methods to deal with flue gas mercury removal, such as adsorption, advanced oxidation and catalytic absorption, and summarizes its advantages and disadvantages. Combined with China's national conditions, the proposed method of synergistic mercury removal using a modified SCR denitration catalyst is currently a more realistic and effective method. The research progress of vanadium-based, manganese-based, and copper-based collaborative denitrification and mercury removal catalysts is reviewed, and the prospects are prospected. The development trend of synergistic denitrification and mercury removal catalysts.
