Beschreibung
Zusammenfassung:	A process for removing at least one product from coal tar is described. The process involves extraction with an extraction agent or adsorption with an adsorbent. The extraction agent includes at least one of amphiphilic block copolymers, cyclodextrins, functionalized cyclodextrins, and cyclodextrin-functionalized polymers, and the adsorbent includes exfoliated graphite oxide, thermally exfoliated graphite oxide or intercalated graphite compounds. Cette invention concerne un procédé pour éliminer au moins un produit du goudron de houille. Le procédé implique une extraction à l'aide d'un agent d'extraction ou un adsorption à l'aide d'un adsorbant. L'agent d'extraction comprend au moins des copolymères séquencés amphiphiles et/ou des cyclodextrines et/ou des cyclodextrines fonctionnalisées et/ou des polymères à fonction cyclodextrine, et l'adsorbant comprend un oxyde de graphite exfolié, un oxyde de graphite thermiquement exfolié ou des composés de graphite intercalaire.
