Abstract: Due to the more intense environmental stress, more attention has been paid to volatile organic compounds (VOCs), which is a precursor of PM_2.5. Combustion is a widely used technique for the removal of VOCs. This paper reviewed the recent progress of technologies for VOCs removal by combustion. VOCs combustion can be divided into two categories:non-catalytic combustion, catalytic combustion. For non-catalytic combustion, we summarized the state of art technologies of direct combustion, regenerative combustion and porous media combustion, and discussed the factors that affect the combustion efficiency. For catalytic combustion of VOCs, the research progress of some main catalysts was reviewed, in terms of noble metal catalysts, non-noble metal catalysts and metal oxide catalysts, the deactivation of catalyst were discussed, the characteristics of catalyst deactivation of catalyst was discussed. The advantages and disadvantages of each kind of catalyst were pointed out. The noble metal catalysts have higher activity, but exhibit a higher price and lower stability. Non-noble metal catalysts are cheaper and have a long lifetime, but the ignition temperature is higher. The metal oxide catalysts have a high activity, and good stability, but the preparation procedure is more complex. In conclusion, the research prospect on this field was also given.

Key words: volatile organic compounds (VOCs), regenerative combustion, porous media combustion, catalytic combustion, catalyst

摘要： 随着环境问题的日益严重，治理作为PM_2.5前体的挥发性有机物（VOCs）越来越受到重视，燃烧法是目前常用的处理VOCs污染物技术之一。本文从燃烧的机理出发综述了燃烧法处理VOCs的研究进展，将燃烧法分为两大类，即非催化燃烧法和催化燃烧法。非催化燃烧法中从燃烧方式出发，总结了直接燃烧法、蓄热式热力燃烧法、多孔介质燃烧法的研究进展，并对燃烧影响因素进行了综述。在催化燃烧法中阐述了贵金属催化剂、非贵金属催化剂和复合金属氧化物催化剂的研究进展，探讨了催化剂的失活问题，分析了每种催化剂的优势与不足。贵金属催化剂活性高，但是价格昂贵、稳定性差；非贵金属催化剂价格低廉、寿命长，但是起燃温度高；复合金属氧化物催化剂活性高、抗毒性强，但是制备工艺复杂。最后基于目前的研究现状和不足，展望了未来燃烧法处理VOCs的研究方向为：结合实际应用的工艺条件和催化燃烧的机理，制备出活性高、价格低廉、抗毒性强和寿命长的催化剂用于蓄热式催化燃烧技术；将催化燃烧和多孔介质燃烧相结合，开发出高效、稳定、经济的燃烧技术处理VOCs污染物。
