The removal of gaseous carbon disulfide (CS2) via dielectric barrier discharge (DBD) combined with MnO2 catalysis has been investigated. CS2 removal and energy yield (EY) had been examined as a function of catalyzer position in DBD reactor, initial CS2 concentration, input power, and gas residence time. The results showed that DBD combined with MnO2 catalyst can improve the CS2 energy and removal efficiency, and MnO2 catalyst placed in afterglow area can enhance the CS2 removal efficiency by about 10 % as compared with DBD treatment only. When increasing initial CS2 concentration and flow rate, a higher EY is obtained. The possible CS2 removal pathways by DBD combined with MnO2 were proposed based on the product identification by FT-IR.
