Abstract
Superimposed barrier discharge and activated carbon filter hybrid systems were used to remove toluene and TCE from air streams. The superimposed barrier-discharge consisted of silent and surface discharges. Experiments were conducted for the gas flow rates from 1 to 10 L/min, applied power from 0 to 7 W and toluene and TCE initial concentrations from 0 to 2,000 ppm for 60 Hz ac applied voltage conditions. Discharge by-products were measured by FTIR, GC, and TLV-VOC detectors. The results show that 1) the toluene-decomposition efficiency monotonically increases with increasing applied power; 2) approximately 90% of the toluene is removed by the plasma reactors and up to 98% is removed by the hybrid system; 3) TCE removal is enhanced by the hybrid system and up to 50% is removed by a discharge reactor alone; 4) the pressure drop of the reactor and carbon filter increase with increasing gas flow rate; 5) TCE is decomposed to form CO2, H2O and Cl2 and, except for the CO2 and H2O, these discharge by-products are absorbed in the activated carbon filters; 6) no COCl2 , HCl, CO, NOx and O3 are observed in the discharge by-products; and 7) the energy yield for toluene decomposition is as high as 26 g/kWh, and as high as 15 g/kWh for TCE decomposition.
