Abstract
A process is described for regenerating exhausted zeolitic catalysts containing titanium and deriving from oxidation processes of organic substrates with hydrogen peroxide. Said process consists in carrying out a treatment in an aqueous medium with hydrogen peroxide in the presence of inorganic fluorinated compounds, subsequent to thermal treatment of the exhausted catalyst.
