Catalytic Wet Peroxide Oxidation of Olive Oil Mill Wastewater over Copper Bearing Zeolite Based Catalysts

Production of olive oil is traditionally of primary economical importance to the countries of the Mediterranean region. During the extraction process excessive amount of phytotoxic wastewater that contains a number of harmful organic contaminants such as lignin, tannins and especially dangerous phenolic compounds is produced. The presence of these toxic molecules makes olive oil mill wastewater (OOMW) a serious threat to the ecosystems into which it’s released, often without prior treatment. Catalytic wet peroxide oxidation, known as CWPO process is one of the methods that can be used for the minimization of phenolic pollution in practice. Catalyst based on Cu supported on 13X zeolite has been prepared and tested for catalytic wet peroxide oxidation of olive oil mill wastewater. Activity and stability of such prepared catalysts was tested in catalytic wet peroxide oxidation of olive oil mill wastewater. Influence of reaction parameters and postsynthesis treatment on their catalytic properties was investigated. Acquired experimental data was tested to a proposed kinetic model for total phenols oxidation and hydrogen peroxide decomposition.
