Recovery of Arenes from the Reformate of Gasoline Fraction by Combined Method of Extraction and Azeotropic Distillation

摘要

Recovery of arenes C_7-C_9 from the reformate of the gasoline fraction by a combined method was studied. The method consists in extraction with a mixed extractive agent composed of triethylene glycol, sulfolane, and water, followed by removal of saturated hydrocarbons from the extract phase by azeotropic distillation with ethanol.
