中文摘要：

芳香烃（Aromatic hydrocarbon）是大气环境中组成复杂、普遍存在的一类持久性有机污染物，其中多环芳烃（PAHs）和苯、甲苯、乙苯、对二甲苯（BTEX）等物质不仅能够参与光化学氧化物、酸雨的形成，同时还具有突出的“三致”效应，严重危害生态环境和人体健康。因此，控制烟气中芳香烃特别是PAHs和BTEX的排放已成为国内外大气和环境科学界共同关注的前沿热点问题之一。在烟气气态芳香烃的净化技术中，吸附技术以其在脱除效果、能耗和实用性等方面显示出的独有优势，已成为控制烟气中微量有机污染物最具潜力的技术之一。通过综合国内外近年来在利用吸附技术脱除烟气中芳香烃的研究，从吸附剂的选择、吸附过程的影响机理、吸附剂的改性以及数学模型等4个方面，阐述吸附技术在该领域的研究进展和未来的发展方向。

英文摘要：

Aromatic hydrocarbons, as one of persistent organic pollutants, are widely accumulated in the air environment with complicated structure. PAHs and BTEX are harmful to the environment and health of people, because they are precursors of photochemical oxidants and agents of the acid rain, and their high degree of mutagenicity and carcinogenicity. Therefore, emission control of gaseous aromatic hydrocarbons in flue gas has increasingly become an interesting subject in the fields of atmospheric and environmental science. Among the purifying technologies, adsorption is a relatively promising approach to remove aromatic hydrocarbons from flue gas as its advantages over high removal efficiency, low energy consumption and easy using. Recent studies on choice of the sorbents, influencing factors, surface modification and adsorption removal model of aromatic hydrocarbons from flue gas were reviewed, the developing tendency of adsorption techniques for removal of aromatic hydrocarbons were also discussed.
