Abstract

The performances of three different types of plasma reactors such as ferroelectric packed-bed (FPB), pulsed corona (PCR), and silent discharge (SDP) were compared in the decomposition of trichloroethylene (Cl2C=CHCl, TCE), bromomethane (CH3Br), and tetrafluoromethane (CF4). Irrespective of reactors, HAP reactivity decreased in the order: TCE > CH3Br > CF4. Similar byproducts were obtained with any of the above reactors, and similar trends were observed in the HAP decomposition rate-retarding effect by gaseous oxygen and water. In the TCE decomposition, PCR was extremely effective and 1,000 ppm of TCE almost completely decomposed in dry nitrogen at 0.09 s of residence time, but its performance went down in the CH3Br decomposition. Comparable performances were observed for FPB and SDP, and CF4 conversions were little higher with SDP than with FPB at the same specific energy densities.
