催化燃烧法处理挥发性有机化合物研究进展

Research progress in catalytic combustion of volatile organic compounds

挥发性有机化合物(VOCs)是大气环境污染的主要来源之一,目前催化燃烧法已成为VOCs最为有效的处理技术。从催化剂种类、活性成分、催化特性及应用等方面对贵金属、非贵金属催化剂(包括过渡金属氧化物、尖晶石型、钙钛矿型催化剂)进行了阐述,同时重点综述了硫对催化燃烧VOCs反应过程的影响,针对现有催化剂抗硫能力差,提出今后催化燃烧催化剂的改进方向和研发重点,展望未来发展前景。

VOCs is one of the major sources of air pollutions. The catalytic combustion method is one of the most effective techniques of removing volatile organic compounds. In this review, the catalytic combustion of VOCs with regard to active species such as noble metal catalysts, mixed metal oxides, spinel and perovskites catalysts, catalyst species, active components, characteristics and application of catalysts are evaluated. Furthermore, the effect of sulfur on the catalytic combustion process is discussed. According to the different abilities of sulfur tolerance, some relevant proposals are made in order to improve the catalytic sulfur resistance. Finally, its development prospect is presented and the prospect for development of the catalysts is also made.
