摘要：

A novel alternating current non-thermal multi-arc plasma generator with three pairs of electrodes was developed for styrene degradation. The experimental results indicated that multiple arcs enhance the destruction of styrene in the reactor. Styrene is not only thermally decomposed but also oxidatively degraded in the multi-arc reactor. When the concentration of styrene is not higher than 1200 mg/m(3), its removal rate can reach more than 90%. The major gaseous effluence products were CO and CO2. The solid product carbon black was found to be attached to the reactor wall. The main intermediates of styrene decomposition are butanol, ethyl acetate and benzaldehyde.
