The extractive desulfurization of dibenzothiophene（DBT）,benzothiophene（BT）,and 4,6-dimethyldi-benzothiophene （4,6-DMDBT） in model oil was carried out using anhydrous FeCl_3 and 1-methyl-3-octylimidazolium chlori...The extractive desulfurization of dibenzothiophene（DBT）,benzothiophene（BT）,and 4,6-dimethyldi-benzothiophene （4,6-DMDBT） in model oil was carried out using anhydrous FeCl_3 and 1-methyl-3-octylimidazolium chloride system（[Omim｜Cl·2FeCl_3）.This new system exhibited high extractive efficiency and the sulfur removal of DBT in model oil（V_（IL）/V_（oil）=1/20） could reach 99.4%at room temperature for 30 min,which was obviously superior to single[Omim]Cl as extractant（22.9%）.When the[Omim｜CI·2FeCl_3 was used,the S-removal of 4,6-DMDBT and BT could also be up to 99.3%and 96.2%, respectively.Moreover,the ionic liquid could be recycled five times without a significant decrease in extractive ability.展开更多
