Experimental Study on the Removal of SO2, NO and Hg0 from Coal-fired Flue Gas by Plasma Oxidation-Activated Carbon Adsorption Technology

燃煤烟气中的SO2、NO和Hg0通常采用在燃煤锅炉后分设烟气脱硫、烟气脱硝和活性炭喷射装置来实现控制。这种分级治理模式存在占地面积大、投资和运行成本高、烟气系统稳定性差等问题。本文在总结各种污染控制技术的基础上，提出了一种等离子体氧化与活性炭吸附结合的同时脱硫脱硝脱汞工艺，即：燃煤烟气中的SO2、NO和Hg0先通过等离子体氧化为易处理的SO3、NO2和Hg2+，再利用活性炭吸附氧化产物，实现多污染物一体化脱除。 本文以玉米秸秆为原材料，通过热解炭化和等离子体改性制备了一种高效脱汞吸附剂。等离子体改性可以显著改变生物炭表面官能团含量和种类，并对孔隙结构破坏程度较小。增加放电气体中O2和水蒸气的...Conventionally, the removal of sulfur dioxide, nitric oxide and elemental mercury are realized by the desulfurization, denitrification and activated carbon injection methods, respectively. The deficiencies of this strategy are larger occupying area, higher cost of construction and operation and poor stability of systems. On the basis of summing up all kinds of pollution control techniques, we prop...学位：工学博士院系专业：环境与生态学院_环境工程学号：3332013015391
