Abstract

The removal of flowing SO₂ was studied in the absence of NH₃ by cold plasma generated by high frequency dielectric barrier discharge.The results showed that the decomposition rate was over 70% at the experimental conditions of 12 kV input voltage and 55% relative humidity with the SO₂ concentration of 5400 mg/m³ and the gas flux of 0.36 m³/h.The added H₂O(g) played an important role in the SO₂ removal, and in addition, the increasing O₂ and input voltage exerted a little influence on the decomposition rate of SO₂.The desulfurization mechanism was also discussed under the analysis of experimental results.

Key words: dielectric barrier discharge, desulfurization, flowing, cold plasma
