The aim of this study is to investigate the possible use of a 1,2-dimethylimidazolium ionic liquid, 2,2-bis((1,2-dimethylimidazolium)methyl)propane-1,3-diol hexafluorophosphate (1), as an adsorbent to selectively remove aromatic heterocyclic sulfur compounds from model fuels. The result indicates that adsorbent 1 is insoluble in model fuels. The spent IL saturated sulfur compounds could be regenerated by a water dilution process. The influence of extraction time or temperature as well as the molar ratio of 1 to aromatic heterocyclic sulfur compound was also studied.
