ABSTRACT:
Process for removing phenols from phenol-containing streams such as coal liquids by contacting the stream with a multivalent metal composition selected from the group consisting of oxides and/or hydroxides of one or more multivalent metals capable of forming a hydroxy metal phenate with the phenols of the stream; separating the hydroxy metal phenate from the treated stream; and heating the hydroxy metal phenate to its decomposition temperature, thereby forming phenols and oxides of the multivalent metal.
