Gaseous Phase Toluene Removal by Non-thermal Plasma coupled with Nano-Ba0.8Sr0.2Zr0.1Ti0.9O3
In the field of air pollution control, the NTP technology has been tested for the abatement of various types of hazardous air pollutants such as volatile organic compounds (VOCs), SO2, NOx etc. But there are two key factors required for the further development of NTP technology to reduce energy consumption and t℃ontrol unwanted byproducts. In order to resolve these two problems, we tried the combination of NTP generated by DBD with nano-Ba0.8Sr0.2Zr0.1Ti0.9O3 catalyst for toluene removal from a gaseous influent at the room temperature and atmospheric pressure. Effects of electric field strength, toluene concentration of influent, flow velocity, reactor packing and material of the fillers on toluene decomposition efficiency were determined. Removal efficiency of toluene increases with increasing electric field strength and influent flow velocity. Packed materials coated nano-Ba0.8Sr0.2Zr0.1Ti0.9O3 catalyst improves the decomposition efficiency resulted greatly, and reduces power consumption on treating with the same quantity of toluene. The best decomposition efficiency of toluene arrives at 95%. Byproducts include aldehyde, alcohols, amide, and benzene derivative by GC-MS.If electric field strength is enough strong, the final resultants will be CO2, CO and H2O.
