Накратко на български
Кислородните добавки в бензина, като например MTBE, се изследват чрез мокро пероксидно окисляване с железни зеолити. Това помага за пречистването на замърсените води, тъй като тези вещества трудно се разграждат в околната среда.

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. The complete Publishable Summary can be found attached.

Цел на проекта
Fuel oxygenates were developed in the 1970s as octane enhancers. Methyl tertiary butyl ether (MTBE) is by far the most commonly used oxygenate worldwide. Ethyl tertiary butyl ether (ETBE), having similar physical-chemical properties, is becoming a preferred alternative to MTBE in some countries due to tax incentives connected with biomass-derived ethanol which is utilized in ETBE production. As a result of its physical-chemical properties and resistance to biodegradation, MTBE persists in groundwater for long time. Several highly MTBE-polluted sites have been identified in Europe in the last years, particularly in Germany. The currently applied processes for removal of MTBE from groundwater (e.g. stripping and adsorption on activated carbon) require high operation costs. With regard to cost-effective management of contaminated sites and accomplishing the new EU chemical legislation there is clearly a need for the development of innovative, safe and efficient technologies of fuel oxygenates treatment. The main scientific aim of the present project is the assessment of wet peroxide oxidation (WPO) of fuel oxygenates (mainly MTBE and ETBE) using innovative catalysts based on Fe-containing zeolites. The project combines two main objectives: I) improvement of the knowledge about the mechanisms of the catalytic process II) proof-of-principle of the developed process by means of a pilot scale test at a field site In the first period laboratory experiments will be conducted involving (1) synthesis and/or selection of new Fe-containing zeolites, (2) characterization of the catalysts, (3) catalytic activity tests under different conditions including column experiments and (4) studies on the reaction mechanism. In the second period the knowledge acquired in the laboratory experiments will be applied for a pilot scale test under real conditions.
