摘要
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.
