摘要
The removal of sulfur compounds(thiophene) from petroleum via extraction with ionic liquids was systematically studied.The ionic liquid[BMIM][PF_6]([BMIM]^+—1-butyl-3-methylimidazolium hexatiuorophosphate 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℃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.
