Abstract

The ionic liquids l-Butyl-3-methylimidazolium-CobaIt Chloride ([BMIM]CoCl3) was utilized as the solvent for the extractive desulfurization of model oil (Dodecane) and diesel fuel at different temperatures and ratios of [BMIM]CoCl3 and Dodecane or Diesel. The extraction performance was tested first using dodecane spiked with known quantity of Dibenzothiophene (DBT) before moving to the commercial diesel from refinery. The amount of DBT extracted decreases with increasing temperature of the extraction. Nevertheless the extraction performance on the model oil seems to be almost complete with extremely little sulfur left over. [BMIM]CoCl3 was found to work best at ambient temperature of T^25°C as the DBT extraction for every single ILs:Oil ratio tested resulted in complete is extraction.. A test with non-sulfur component spikd in the dodecane shows that the ionic liquid did not extract it. The [BMIM]CoCl3 shows great potential to be an excellent sulfur extractant agent especially DBT compounds in both model oil and real diesel.
