| Abstract | In a series of studies on precleaning technology based on sulfur forms, an advanced desulfurization process that can be carried out under mild conditions has been developed for the production of clean sulfur-free fuel. The selectivity of adsorption of various metal compounds to thiols, sulfides, and thiophenes in a model fuel at room temperature was investigated. Among the studies metal compounds, lead oxide showed the highest selectivity to aliphatic and aromatic thiols. For the extraction of thiophenic sulfur selectively from the fuel, halogen-free ionic liquids with different alkyl chain lengths were prepared. The extraction yield of dibenzothiophene increased linearly with an increase in the length of alkyl chains and mass ratio of the ionic liquid to the model fuel. |
