摘要：
The removal of sulfur compounds (thiophene) from petroleum via extraction with ionic liquids was systematically studied. The ionic liquid [BMIM][PF6]([BMIM](+)-1-butyl-3-methylimidazolium hexafluorophosphate cation) was used to investigate its effect on thiophene removal. The test results showed that a higher temperature and a greater mass ratio of the ionic liquids versus the oil containing the sulfur compounds both helped to remove the thiophene from the feed oil. At a temperature of 60 degrees C and an ionic liquid/feed oil mass ratio of 20%, the desulfurization rate could reach 52.39%, with the extraction time specified at 40 minutes.
