Appl. No.:

7/290330

Olin Corporation - Cheshire CT

International Classification:

B01D 1504
B01J 2002

US Classification:

210694

Abstract:

Aromatic hydrocarbons are readily recovered from aqueous solutions by contacting the aqueous solution with an oxidized activated carbon having a low concentration of acidic oxides. The novel oxidized activated carbon is produced by contacting activated carbon with an acidic oxidizing agent which is used in low concentrations. The process can be employed to reduce aromatic hydrocarbons such as benzene from aqueous solutions such as industrial effluents or potable water supplies to levels permissible by environmental protection regulations.
