The extractive desulfurization of simulated fuel containing dibenzothiophene (DBT) and thiophene as sulfur compounds was carried out using SnCl 2 .2H 2 Obased Deep Eutectic Solvent (DES). High performance liquid chromatography (HPLC) was employed for the quantitative monitoring of the sulfur compounds in the fuel. The results showed that the DES exhibits higher desulfurization efficiency for DBT than thiophene. Optimum extraction conditions have it that, extraction efficiencies as high as 69.57% and 47.28% can be achieved with the solvent in a single stage for DBT and thiophene respectively. The work has not only shown that SnCl 2 .2H 2 Obased DESs can be used in desulfurization of liquid fuels but also proved their promising desulfurization ability in the presence of multi-component fuel.
