摘要
工业燃煤是挥发性有机物(VOCs)主要排放源之一,VOCs是臭氧和二次有机气溶胶形成的关键前驱体,对环境和人体健康造成危害。总结现阶段常见的VOCs治理方法及减排技术,综述燃煤工业废气VOCs催化燃烧技术中催化剂选型及开发等方面的研究进展,对比分析钙钛矿型催化剂掺杂改性、制备方法等对其催化VOCs活性的影响,且对工业燃煤废气多污染物协同减排技术进行展望。钙钛矿作为具有发展前景的重要催化材料,将其应用于工业烟气VOCs减排领域具有较高的可行性,开发高效稳定且具多污染物协同减排功效的钙钛矿型催化剂具有重要的应用价值。
Industrial fuel combustion activities are the main source of volatile organic compounds(VOCs)emissions.VOCs are key precursors to the formation of ozone and secondary organic aerosols,causing hazards to the environment and human health.The current common VOCs control methods and emission reduction technologies were summarized,and the research progress on catalyst selection and development in the catalytic combustion technology for industrial flue gas VOCs was reviewed.The effects of doping modification and preparation methods of perovskite catalysts on the catalytic activity were compared,and the collaborative multi-pollutant abatement technologies for industrial flue gas were expected.Perovskite,a potential catalytic materials,exhibits high feasibility for industrial flue gas VOCs abatement.It is necessary to develop an efficient and stable perovskite catalyst with multi-pollutant co-reduction performance.
