摘要
In order to overcome the high energy consumption and discharge of byproducts for decomposition of hydrogen sulfide with non-thermal plasma (NTP) alone, a two-stage system of NTP and activated carbon fibers (ACF) was presented for decomposition of H2S. The effects of two-stage system and single NTP system on H2S removal efficiency and byproducts were investigated at different input voltage. The synergistic mechanisms of NTP and ACF for H2S decomposition were also analyzed. The two-stage system could remarkably improve the H2S removal efficiency, decrease the energy consumption and remove byproducts, while prolong the breakthrough time of ACF and increase the decomposition and adsorption capacity for H2S. The results showed that the two-stage system improved 15% of the H2S removal efficiency and reduced 26.5% of the energy consumption at 6 kV with a gas-flow rate of 11.8 m3/h. The energy consumption of the two-stage system at 6 kV reduced 26.5%. ACF could remove the SO2 and O3, no SO2 and O3 were detected before the breakthrough time of ACF for H2S. The breakthrough time of ACF for H2S was prolonged from 2 to 16 times by NTP at the input voltage range from 3 to 7 kV.
