Deep oxidative desulfurization of model fuel via dielectric barrier discharge plasma oxidation using MnO2 catalysts and combination of ionic liquid extraction

- A novel catalytic oxidative desulfurization method was developed.
- DBD air plasma was used to oxidize sulfur compounds in model fuel.
- [BMIM]CH3COO was used as extracting agent.
- MnO2 catalysts could effectively improve the desulfurization performance.
- The sulfur removal of TS, BT, DBT and 4,6-DMDBT could reach above 90.0%.
