摘要：
A method of recovering crude oil from crude oil drenched adsorbent and simultaneously regenerating the adsorbent to render it suitable for re-use in crude oil adsorption. The method includes contacting crude oil drenched adsorbent, in the form of solid nanofibrous expanded polystyrene drenched with adsorbed crude oil, with a non-polar solvent, thereby obtaining regenerated crude oil lean adsorbent and crude oil rich solvent.
