摘要
Abstract
Mercury is toxic and easy to enrichment,it is one of the main pollutants control object in the future. Al-though,as a relatively mature technique, the activated carbon injection technologycan make the average mercury removal rate reach to 80%~98%, but high operating costs becamethe restrictionfor large-scale business development. Fly ash, as the waste of coal-fired power plant,not only is low cost, butalso with mercury capture capability. The mercury removal capacityof certain fly ashes can even reach commercial activated carbon levels. Currentlyresearcheson mercury removal rate of fly ash were reviewed in this paper. Theinfluence of gas atmosphere, coal type, the carbon content of fly ash, fly limestone phase structure and other factors on the fly ash mercury removal rate was discussed in this article. Results showed that fly ash as ab-sorbent is feasible, but still some difficulties should be solved.关键词
