Sažetak
Catalytic wet peroxide oxidation (CWPO) is one of new emerging oxidation processes particularly attractive for the treatment of industrial wastewater which is unsuitable for incineration or biological treatment. The process is operated at mild conditions (0.1-0.5 MPa, T≤ 100 &ordm ; C), and therefore with low energy requirements with the addition of different types of (classic) catalysts such as composite metal oxides. In the recent years, only a few studies dealing with the use of zeolites containing copper were reported, making this aspect of the process open for further investigation. It has been reported in the open literature that metal bearing zeolites prepared using classical procedures show severe metal leaching, leading to side reactions catalyzed in homogeneous phase. The aim of the present work is to study a heterogeneous catalytic wet peroxide oxidation of phenol as a model component using copper bearing FAU, BEA and MFI zeolites prepared by direct hydrothermal synthesis. The non-classical method of preparation resulted in low leaching of active metal components.
