Zusammenfassung:ABSTRACT 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. L'invention concerne un procédé de récupération de pétrole brut à partir d'un adsorbant trempé de pétrole brut et de régénération simultanée de l'adsorbant pour le rendre approprié pour une réutilisation dans l'adsorption de pétrole brut. Le procédé comprend la mise en contact d'un adsorbant trempé de pétrole brut, sous la forme d'un polystyrène expansé nanofibreux solide trempé de pétrole brut adsorbé, avec un solvant non polaire, ce qui permet d'obtenir un adsorbant régénéré pauvre en pétrole brut et un solvant riche en pétrole brut.
