Solvent extraction of thiophene from n-alkanes (C7, C12, and C16) using the ionic liquid [C8mim][BF4]

A study on the liquid–liquid equilibria of 1-alkyl-3-methylimidazolium hexafluorophosphate with ethanol and alkanes

“…This behavior was also found for other solutropic mixtures in the literature [30,31]. The standard deviation in the correlation of these solutropic mixtures is high [31] because these equations show a handicap in high ethanol compositions when the solutropic mixture changes from having positive slopes to having negative ones.…”

Pervaporative desulfurization of gasoline: A review

“…Interestingly, the nitrogen compounds are found to be significantly better extracted when compared to organosulfur compounds [29]. Many studies confirm that the removal of sulfur compounds can modify the content of aromatics in gasoline, which can be problematic for maintaining octane number in gasoline [30][31][32]. Moreover, the regeneration of ionic liquid is expensive, and often several consecutive extractions are needed to reduce sulfur content from 300 to 10 ppm.…”

Recent Advances in the Science and Technology of Desulfurization of Diesel Fuel Using Ionic Liquids

“…In addition Ionic liquids are immiscible with fuel, and the used Ionic liquids can be regenerated and recycled by solvent washing or distillation [5][6][7][8][9]. The desulfurization using ionic liquids has received growing attention [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. 6 as extractant, acetic acid as catalyst, and H 2 O 2 as oxidant, the sulfur removal of DBT in model oil was increased significantly to 85%.…”
