| Abstract: | "The combination of a multistage rod plasma reactor and post CeO(2)-MnO(x) catalysts is studied to treat dimethyl sulfide (DMS). The physicochemical properties of all catalysts and the effect of the catalytic performance of CeO(2)-MnO(x) catalysts on DMS removal efficiency are studied. Placing CeO(2)-MnO(x) catalysts after the non-thermal plasma system can improve the capability of DMS degradation. The results exhibit that CeO(2)-MnO(x) (1:1) catalyst presents a higher catalytic activity than that of CeO(2), MnO(x), CeO(2)-MnO(x) (1:0.5) and CeO(2)-MnO(x) (1:3). At the power of 21.7 W, the combination of dielectric barrier discharge and CeO(2)-MnO(x) (1:1) catalyst could improve the DMS removal efficiency and CO(2) selectivity by 16.2% and 18.2%, respectively. This result maybe closely related with its specific surface area, redox properties and oxygen mobility. In addition, the degradation mechanism of DMS over CeO(2)-MnO(x) catalysts is proposed. Finally, the stability of the CeO(2)-MnO(x) (1:1) catalyst is investigated, and the reason for the decreased activity of the used catalyst is analyzed" |
