Assessment of wet peroxide oxidation using innovative catalysts for removal of fuel oxygenates from contaminated water

Final Report Summary - FUEL OXYGENATES WPO (Assessment of wet peroxide oxidation using innovative catalysts for removal of fuel oxygenates from contaminated water)

Oxygenated compounds are added to gasoline in order to improve fuel combustion efficiency and to lower exhaust emissions of CO and hydrocarbons. MTBE is the most important fuel oxygenate used worldwide. MTBE is considered as a unique contaminant due to its ability to move readily throughout various environmental compartments and to its resistance to degradation. The contamination of water supplies by MTBE and other fuel oxygenates is a problem of increasing concern. Some high gasoline polluted sites have been identified in Europe in the last years, particularly in Germany. In that sense, the main scientific objective of the present project is the assessment of wet peroxide oxidation (WPO) of fuel oxygenates using innovative catalysts. This purpose was achieved by using Fe-Zeolites as catalysts and combining their properties to adsorb fuel oxygenates and to catalyze Fenton-like reactions. The main project objectives were: (Obj. 1) synthesis and/or selection of new Fe-zeolites, (Obj. 2) characterization of the catalysts, (Obj. 3) catalytic activity tests under different conditions, (Obj. 4) studies on the mechanisms of reaction and (Obj. 5) optimization of the catalyst and the design of the treatment process.
