Desulfurization of real fuels with [BMIM]Cl.

Diesel to IL (mass ratio)	S-content (ppmw)	S-removal (%)	Gasoline to IL (mass ratio)	S-content (ppmw)	S-removal (%)
5 : 1	210.4	45.3	5 : 1	70.3	61
3 : 1	160	58.4	3 : 1	54.8	70
1 : 1	132.1	66	1 : 1	46.8	74

Temperature = 30°C, extraction time = 30 min, initial sulfur concentration of diesel and gasoline = 385 and 186 ppmw, respectively.
