AbstractThe FeCl3-containing Lewis-acidic ionic liquids (ILs) [C(6)mim]Cl/FeCl3(1:1.5), [C(6)mim]Cl/FeCl3(1:2), [C(8)mim]Cl/FeCl3(1:1.5), and [C(8)mim]Cl/FeCl3(1:2) were used as extractants for desulfurization of model fuel and gasoline fuel, respectively. The results demonstrate that these ILs are effective for the removal of sulfur compounds from model fuel under different mass ratio of IL to model fuel (1:1, 1:3, 1:5, 1:10) at 25 degrees C. The extractive performance of ILs increased as the molar ratio of FeCl3 to [C(n)mim]Cl(n=6, 8) varied from 1:1 to 1:2. The selectivity of sulfur compounds by extraction process followed the order of dibenzothiophene (DBT)>benzothiophene (BT)>4,6-dimethyldibenzothiophene (4,6-DMDBT). The sulfur removal of gasoline fuel containing sulfur content of 440.3ppmw could be up to 85.8%; that is to say that the sulfur content of gasoline fuel varied from 440.3ppmw to 62.4ppmw after one extraction stage. Moreover, the [C(6)mim]Cl/FeCl3(1:2) can be recycled for at least 4 times with a little decrease in the desulfurization activity.; The FeCl3-containing Lewis-acidic ionic liquids (ILs) [C(6)mim]Cl/FeCl3(1:1.5), [C(6)mim]Cl/FeCl3(1:2), [C(8)mim]Cl/FeCl3(1:1.5), and [C(8)mim]Cl/FeCl3(1:2) were used as extractants for desulfurization of model fuel and gasoline fuel, respectively.
