Catalytic Oxidation of Olive Mill Wastewater

Catalyst based on Cu supported on 13X zeolite has been prepared and tested for catalytic wet peroxide oxidation of olive oil mill wastewater. The influence of catalyst postsynthesis treatment as well as operating temperature in oxidation process has been studied. The efficiency of the process was evaluated to determine organic compound and total organic carbon reduction. Catalysts' activity decreases when thermally treated catalysts are used in the respect of total phenols oxidation and H2O2 decomposition. The TOC abatement in the CWPO reactions remains unaffected by postsynthesis treatment. The calcined catalyst exhibits significantly higher stability of both active metal component and catalyst's support showing greater resistance to leaching and adsorption of intermediate products.
