Comparison of reactor performance in the nonthermal plasma chemical processing of hazardous air pollutants
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 (Cl/sub 2/C=CHCl, TCE), bromomethane (CH/sub 3/Br), and tetrafluoromethane (CF/sub 4/). Irrespective of reactors, HAP (hazardous air pollutants) reactivity decreased in the order: TCE>CH/sub 3/Br>CF/sub 4/. 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 1000 ppm of TCE almost completely decomposed in dry nitrogen at 0.09 s of residence time, but its performance went down in the CH/sub 3/Br decomposition. Comparable performances were observed for FPB and SDP, and CF/sub 4/ conversions were little higher with SDP than with FPB at the same specific energy densities.
