PROCESS FOR REMOVING A CONTAMINANT FROM COAL TAR

A process for removing at least one contaminant 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, inclusion complexes of poly(methyl methacrylate) and polyc...

More Information
Summary:A process for removing at least one contaminant 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, inclusion complexes of poly(methyl methacrylate) and polycyclic aromatic hydrocarbons, cyclodextrins, functionalized cyclodextrins, and cyclodextrin-functionalized polymers, and the adsorbent includes exfoliated graphite oxide, thermally exfoliated graphite oxide or intercalated graphite compounds.
