REGENERATION OF SOLID ADSORBENT

摘要

The present invention refers to a method of solvent-free regeneration of a solid adsorbent capable of adsorbing sulfones and/or sulfoxides comprising regenerating said adsorbent having sulfones and/or sulfoxides adsorbed thereon by exposing said adsorbent to a heat treatment at a temperature equal or less than 500 C. A further invention refers to a method of separating sulfoxides and/or sulfones from a petroleum based hydrocarbon stream comprising contacting activated carbon comprising -C=O, -COOH, -C-O and -OH functional groups on its surface with said petroleum based hydrocarbon stream.
