Abstract

The scale-up experiments of the decomposition of toluene by pulse corona discharge in wire-plate reactor were investigated. The maximum input power of pulse voltage source and the maximal peak voltage were 1 kW and 100 kV, respectively. The experiments were conducted with a gas-flow rate of 4-16 m3·h-1. Some parameters, such as peak voltage, pulse frequency, initial concentration of toluene, gas-flow rate, which influenced on removal efficiency, had been investigated. The results showed that the removal efficiency was improved obviously when the peak field intensity changed in the range of 9-12.5 kV·cm-1; the removal efficiency was up to 64% when gas-flow rate, peak voltage, initial concentration of toluene, pulse frequency were 4 m3·h-1, 73 kV, 277 mg·m3, 200 pps, respectively; the energy yield of toluene was 3 g·(kWh)-1. A dynamics model was developed to describe the relation of the removal efficiency of toluene with energy density and initial concentration of toluene. The decomposition rate constant of toluene was 0.00353. According to the results, the optimization design for the reactor and the matching of pulse voltage source could be reckoned.
