Abstract: The effects of different concentration of O2, different relative humidity and whether if the existence of dust on the concentration of the main product and removal efficiency of carbonyl sulfide (COS) were investigated through direct current corona discharge. The experiment results show that the removal efficiency of carbonyl sulfide (COS) and the production date of sulfur dio-xide (SO2),TS′ were lower with the increase of oxygen(O2); COS inversion quantity was equal to the gross which CO and CO2. The concentration of CO and CO2 were decreased, the production rate of CO was decreased and CO2 was increased. Relative humidity has affected the removal efficiency of COS less,but it has impact on breakdown voltage. With the increase of relative humidity, SO2 formation rate was decreased and TS′ formation rate was increased. The concentration of CO let up and CO2 was increased. The production rate of CO was decreased and CO2 was increased. After add dust in the experiment process, the removal efficiency of COS was increased in some extent, the production rate of SO2 significantly was decreased and TS′ formation rate was in addition. The concentration of CO was decreased and CO2 was increased. The production rate of CO was decreased and CO2 was increased. The remaval efficiency of COS was the best in the condition of low oxygen, low humidity and the exist of dust.
