摘要

This study compared the conversion of two malodorous substances, dimethyl sulfide (CH3SCH3, DMS) and methanethiol (CH3SH) in a cold plasma reactor. The DMS and CH3SH were successfully destroyed at room temperature. DMS decomposed less than CH3SH at the same conditions. In oxygen-free condition, CS2and hydrocarbons were the major products, while SO2and COxwere main compounds in oxygen-rich environments. The DMS/Ar plasma yielded more hydrocarbons and less CS2than that of CH3SH/Ar plasma. In the CH3SH/O2/Ar plasma, rapid formation of SO and CO resulted in the yields much more amounts of SO2and CO2than those in the DMS/O2/Ar plasma; and remained only a trace of total hydrocarbons, CH2O, CH3OH, CS2and OCS. The major differences between the reaction mechanisms of DMS and CH3SH were also proposed and discussed.
