Study of extractants selectivity for extraction of organosulfur compounds from model solutions

Data on the extraction of aromatic hydrocarbons and of sulfur- and nitrogen-containing compounds from model systems with selective solvents, ionic liquids, and deeply eutectic solvents are discussed. The results of the extraction treatment of light and heavy vacuum gasoils and of visbreaker and delayed coker gasoils are presented. The extraction treatment of vacuum gasoils and gasoils from secondary oil refining processes allows the sulfur content of the raffinate to be reduced to less than 0.5 wt %, which meets the requirements to marine fuels used in open sea. The treatment of visbreaker and especially delayed coker gasoils is considerably more efficient than that of vacuum gasoils. The degree of removal of nitrogen-containing components and polyaromatic compounds with dimethylformamide or N-methylpyrrolidone as an extractant is higher than that of sulfur-containing compounds.
