Process for producing carbon blacks with reduced polycyclic aromatic hydrocarbon content utilizing supercritical fluid extraction |
| abstract |
It is provided a process for producing a purified carbon black with a reduced content of polycyclic aromatic hydrocarbons, the process comprising: (a) providing a carbon black comprising an initial content of polycyclic aromatic hydrocarbons, (b) treating the carbon black comprising an initial content of polycyclic aromatic hydrocarbons with an extraction agent comprising carbon dioxide in a supercritical state to extract at least a portion of the polycyclic aromatic hydrocarbons from the carbon black, and (c) removing the extraction agent comprising the extracted polycyclic aromatic hydrocarbons from the carbon black to obtain a purified carbon black with a lower content of polycyclic aromatic hydrocarbons than the initial content of polycyclic aromatic hydrocarbons. It is furthermore provided a carbon black obtained through said production process and articles made therefrom. |
