Figure 1

Effect of sulfur concentration on desulfurization efficiency: (a) T, 3-MT, BT, 3-MBT, DBT and 4,6-DMDBT, all 166.7 ppm, (b) sulfur content of 83.3 ppm, (c) sulfur content of 55.5 ppm, and (d) sulfur content of 41.67 ppm. Other reaction conditions: NaBH4/S molar ratio = 12, NiCl2/S molar ratio = 3, PEG/oil volume ratio = 1, reaction time = 80 min, stirring speed = 700 rpm, RT.
