Non-thermal plasma (NTP) an emerging technology to treat volatile organic compounds (VOCs) present in unhygienic point source air streams. In present study, double dielectric barrier discharge (DDBD) reactors were used for the first time to evaluate the removal efficiency of VOCs mixture of different nature at constant experimental conditions (input power 16-65.8W, VOCs mixture feeding rate 1-6 L/min, 100-101 ppm inlet concentration of individual VOC). Reactor A and B with discharge gap at 6mm and 3mm respectively, were used in current study. When treated at an input power of 53.7 W with gas feeding rate of 1L/min in DDBD reactor A, removal efficiency of the VOCs were: tetrachloroethylene (100%), toluene (100%), trichloroethylene (100%), benzene (100%), ethyl acetate (100%) and carbon disulfide (88.30%); whereas in reactor B, the removal efficiency of all VOCs were 100 %. Plasma-catalyst (Pt-Sn/Al₂O₃, BaTiO₃ and HZSM-5) synergistic effect on VOCs removal efficiency was also investigated. Highest removal efficiency i.e 100% was observed for each compound with BaTiO₃ and HZSM-5 at an input power 65.8 W. However, integrating NTP with BaTiO₃ and HZSM-5 leads to enhanced removal performance of VOCs mixture with high activity, increase in energy efficiency and suppression of unwanted byproducts.

非热等离子体（NTP）是一种新兴技术，用于处理不卫生的点源空气流中存在的挥发性有机化合物（VOC）。在本研究中，首次使用双介电势垒放电（DDBD）反应器来评估在恒定实验条件下（输入功率16-65.8W，VOCs混合进料速度1-6 L / V / min）不同性质的VOCs混合物的去除效率。最小，单个VOC的入口浓度为100-101 ppm）。当前研究中使用的反应器A和B的放电间隙分别为6mm和3mm。在DDBD反应器A中以53.7 W的输入功率和1L / min的进料速度处理气体时，VOC的去除效率为：四氯乙烯（100％），甲苯（100％），三氯乙烯（100％），苯（100 ％），乙酸乙酯（100％）和二硫化碳（88.30％）；而在反应堆B中 所有VOC的去除效率均为100％。等离子体催化剂（Pt-Sn / Al_{还研究了2} O ₃，BaTiO ₃和HZSM-5）对VOCs去除效率的协同作用。最高去除效率，即在输入功率65.8 W下观察到每种含BaTiO ₃和HZSM-5的化合物的去除率最高。但是，将NTP与BaTiO ₃和HZSM-5结合使用可增强具有高活性的VOCs混合物的去除性能，增加能源效率和抑制有害副产物。
