A wire-mesh catalyst coated by La0.8Sr0.2MnO3 was combined with a dielectric barrier discharge (DBD) reactor for toluene removal at atmospheric pressure. It was found that toluene removal efficiency and carbon dioxide selectivity were enhanced in the catalytic packed-bed reactor. In addition, ozone and nitrogen monoxide from the gas effluent byproducts decreased. This is the first time that ultrasound combined with plasma has been used for toluene removal. A synergistic effect on toluene removal was observed in the plasma-assisted ultrasound system. At the same time, the system increased toluene conversion and reduced ozone emission.
采用 La0.8Sr0.2MnO3 涂层的金属网催化剂与介质阻挡放电（DBD）反应器结合，用于常压下去除甲苯。研究发现，在催化填充床反应器中，甲苯去除效率和二氧化碳选择性得到提高。此外，气体出口副产物中的臭氧和一氧化氮减少。这是首次将超声与等离子体结合用于去除甲苯。在等离子体辅助超声系统中观察到了对甲苯去除的协同效应。同时，该系统提高了甲苯转化率并减少了臭氧排放。
