چکیده انگلیسی
The application of ionic liquids as alternatives to conventional organic solvents in the extraction process has been investigated. In the present study, fourteen species of imidazolium-based ionic liquids were added into the NaOH (aq) to remove the mercaptans. The influences of anion species and cation alkyl chain length of the imidazolium-based ionic liquids on the performance of mercaptan removal from light oils have been discussed. The efficiency of extraction for mercaptans exhibited the order of [Ac]â > [OH]â â [Br]â > [BF4]â. The longer alkyl chain imidazolium-based ionic liquids contributed to enhance desulfurization rate of 1-butyl mercaptan. 100% desulfurization rate of 1-butyl mercaptan was achieved by the anion of Acâ ionic liquids and NaOH (aq) at a volume ratio of 40:1 (V(oil):V(ionic liquid)) and a short equilibrium time within 10 min.
