Abstract
A process for the removal of organosulfur compounds from hydrocarbon materials is disclosed. The process includes contacting an ionic liquid with a hydrocarbon material to extract sulfur-containing compounds into the ionic liquid. The sulfur-containing compounds can be partially oxidized to sulfoxides and/or sulfones prior to or during the extraction step.
