Improving the pollutant removal efficiency of packed-bed plasma reactors incorporating ferroelectric components

摘要: Abstract In this work we have studied the plasma removal of air contaminants such as methane, chloroform, toluene and acetone in two parallel plate packed-bed dielectric barrier discharge (DBD) reactors different sizes. Removal energy efficiencies been determined a function residence time contaminated within reactor, kind material (ferroelectrics or classical materials), frequency incorporation ferroelectric onto active electrode together with inter-electrode pellets filling gap. Results at low small reactor showed an enhancement efficiency (e.g., it was multiplied by factor six three for respectively) yield increased from 22% to 52% chloroform 15% 21% methane). Such enhancements attributed higher electrons lower capacitance found plate-modified configuration. A careful analysis reaction electron distributions investigated conditions simulation electric field necks between ferroelectric/dielectric complete present study. Overall, obtained results prove critical role architecture operating enhanced performance pollution processes using DBD systems.
