Novel plasma reactor using honeycomb ceramics driven by a fast SI-thyristor for environmental applications

摘要

A novel plasma reactor using honeycomb ceramics for NO decomposition was proposed. Using rod-cylinder electrodes configuration with the honeycomb ceramics, a barrier discharge type reactor was fabricated with a PET sheet as an insulator. The uniform discharges in the honeycomb ceramics were successfully obtained using a high voltage pulse generator with a fast SI-thyristor. NO removal experiment in N{sub}2 was carried out with the reactor. The surface condition of the ceramics greatly influenced the NO removal characteristic. The NO removal efficiency of the reactor was estimated to be 295 eV/molecule at the maximum NO removal rate.
