| 摘 要： | 催化燃烧是目前最有效的处理挥发性有机物(VOCs)技术之一.本文从催化剂活性组分、催化剂载体、有效组分颗粒大小、水蒸汽的影响及催化燃烧反应中的积碳等几个方面,对近年来催化燃烧处理VOCs的研究进行了总结.分析表明:贵金属催化剂的研究主要着重于选择有效的载体和双组分贵金属催化剂;非贵金属催化剂的研究主要集中在高活性的过渡金属复合氧化物、钙钛矿和尖晶石型等催化剂的研制,还有这些活性组分粒径大小及载体对催化燃烧VOCs反应活性的影响;此外,在实际应用中,水蒸汽和催化剂积碳失活等问题对催化燃烧VOCs的反应也有很大影响.本文的评述将为选择合适的催化燃烧技术处理VOCs污染物提供一定参考.

| Abstract: | Catalytic combustion is one of the most effective techniques for the removal of volatile organic compounds (VOCs).In this review,the recent developments in catalytic combustion of VOCs with regard to active species such as noble metal catalysts,mixed metal oxides,perovskite and spinel metal oxide phases were examined.The effects of particle sizes of active species,catalyst supports,the water vapor effect and the coking effect on catalytic combustion were evaluated.It is found that the research on noble meta... |
