摘要 综述了现阶段煤基吸附剂脱除烟气中汞的基本情况,重点介绍了飞灰炭与改性活性炭的研究现状。飞灰炭脱汞效果要比活性炭差,较高的飞灰烧失率、大量的中孔结构、表面有大量的含氧官能团和无机成分(S、Cl)对飞灰炭吸附汞有利;改性活性炭主要由含Cl或S的物质进行改性,并且分别介绍了它们各自脱汞的特征。还分析了烟气中极性气体对脱汞的影响。 This paper summarized the basic condition of removing hydrargyrum from flue gas with coal-sorbent nowadays, and emphasized the research actuality of fly ash charcoal and metamorphic active carbon and the character of removing hydrargyrum each. The influence of polar gas on removing hydrargyrum also be mentioned.
