The performance of three different types of plasma reactors such as ferroelectric packed-bed (FPR), pulsed corona (PCR), and silent discharge (SDR) were compared in the decomposition of trichloroethylene (Cl2C= CHCl, TCE), bromomethane (CH3 Br), and tetrafluoromethane (CF4). Irrespective of reactors, hazardous air pollutant (HAP) reactivity in dry N2 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 water. Only for SDR, TCE decomposition was accelerated by O2 in the background gas. The most plausible active oxygen species is considered to be the triplet oxygen atom. In the reaction systems where chemically induced decomposition of HAPs can occur, as in the case of TCE, PCR is expected to exceed FPR and SDR in performance. In the cases of CH3Br and CF4, residence time has been the most important factor governing their decomposition rates, and FPR and SDR have shown higher performance than PCR.
