In this study, a novel desulfurization method was developed by introducing ionic liquid (IL) into the integrated process of reductive desulfurization by NaBH 4 and its regeneration via NaBO 2 electroreduction, where ILs play a dual role of electrolyte and extracting agent. Under the conditions of -2.4 V forward pulse voltage, 0.6 V reverse pulse voltage, 0.6 s forward pulse time, 0.4 s reverse pulse time, 0.8 s turn-off time, 80 min electrolytic time, 4/1 IL/oil volume ratio, sulfur removal reached more than 95% for model fuel oil. Therefore, the novel integrated process of reductive desulfurization by NaBH 4 and its electroreduction regeneration in IL is feasible and promising.
