Abstract
The influence of humidity and oxygen on decomposition of dimethyl sulfide (DMS) was investigated experimentally by a wire-cylinder pulse corona reactor at room temperature. The DMS decomposition efficiency was investigated using varying oxygen concentration (0.6%–21.0%), humidity (0%–1.0%) and different balance gas (air, N2, Ar). DMS conversion in Ar is more efficient than that in N2 and air at a fixed peak voltage. In addition, it is found that 5% oxygen is the optimum concentration in decomposition of DMS, due to higher conversion of DMS and relatively fewer yields of by products, such as O3, NO x and SO2. The highest DMS removal efficiency was achieved with the gas stream containing 0.3% H2O in air.
