Extraction of nitrogen compounds from diesel fuel using imidazolium-and pyridinium-based ionic liquids: Experiments, COSMO-RS prediction and NRTL correlation
Ethyl-3-methylimidazolium ethyl sulfate ([EMIM][EtSO 4]), 1-ethyl-3-methylpyridinium ethyl
sulfate ([EMPY][EtSO 4]) and 1-ethyl-3-methylimidazolium methanesulfonate ([EMIM][MeSO
3]) ionic liquids were investigated to remove pyrrole, indoline, pyridine and quinoline
nitrogen compounds from n-hexadecane. Twelve sets of ternary liquid–liquid equilibrium
experiments were conducted at room temperature and atmospheric pressure with feed
concentrations of nitrogen compounds ranging between 5 and 50 wt%. The ternary phase …
