The olive oil production industry consumes high quantities of fresh water and produces highly polluted olive oil mill wastewater (OOMW). Among the organic fraction compounds present in the OOMW, tyrosol and phenolic acids are most commonly found. The presence of these compounds makes the OOMW phytotoxic and biorefractory in nature and unsusceptible to the direct biological treatment. The non-selective catalytic wet peroxide oxidation process (CWPO) is one of the methods that can be used for reducing the toxicity of OOMW in practice [1]. With the use of catalysis the process can be successfully operated under mild conditions (T < 353 K, p=atm.) with low energy consumption. Different zeolite based catalyst containing an active metal cation have shown to possess good activity in the wet peroxide oxidation of phenolic compounds. In this study, the influence of active metal cation species and Si/Al ratio in the parent commercial BETA zeolite catalysts on their physical, chemical and catalytic properties was investigated. |
