摘要

This study aims to investigate the destruction and energy efficiencies of SF_6 or CF_4 via DBD (dielectric barrier discharge) and CPC (combined plasma catalysis), respectively. For SF_6 removal, the removal efficiency achieved with DBD is higher than that with CPC at the same applied voltage. Possible reasons include plasma characteristics of packed-bed reactor and poisoning of catalyst caused by S in SF_6. It deserves further investigation for real causes. Additionally, the influences of H_2O(g) on removal of SF_6 and CF_4 are investigated as well. The result indicates that adding H_2O(g) is beneficial for removing SF_6, but not for CF_4. As for the energy efficiencies, the highest value for SF_6 is 3.45 gSF_6/kWh, corresponding to 8.2 × 10~4gCO_2/kWh, while the best results for CF_4 in gCF_4/kWh and gCO_2/kWh are 1.93 and 1.3 × 10~4, respectively.
