Sažetak
One of the new emerging oxidation processes - catalytic wet peroxide oxidation (CWPO) is being studied for the use in the treatment of industrial wastewater. This method of waste treatment is specially appealing from the ecological standpoint due to its ability to eliminate pollutants as oppose to classical oxidation that results in turning the pollution from one form into another. 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 catalysts. 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 investigations.1, 2 It has been reported that metal bearing zeolites prepared using classical procedures show severe metal leaching, leading to side reactions catalyzed in homogeneous phase.3 The aim of the present work is to study heterogeneous catalytic wet peroxide oxidation of phenol using copper bearing FAU and MFI zeolites prepared by direct hydrothermal synthesis. The effect of the presence of the inorganic cation in the zeolite structure, as well as leaching of the active metal component were also studied. Presented on: COMO, III.
