Influence of Operational Parameters and Kinetic Modelling of Catalytic Wet Air Oxidation of Phenol by Al/Zr Pillared Clay Catalyst

Single and mixed oxide Al/Zr-pillared clay (Al/Zr-PILC) catalysts were synthesized and tested for catalytic wet air oxidation (CWAO) of aqueous phenol solution under milder conditions, in a semi-batch reactor. The catalysts were synthesized from natural bentonite clay using ultrasonic treatment during the aging and intercalation steps and were characterized <...

Kinetic modelling of catalytic wet air oxidation of phenol by simulated annealing

A detailed reaction network for the catalytic wet air oxidation (CWAO) of phenol on a CuO/ -Al2O3 catalyst is proposed in this study. The reaction network proposed accounts for all detected intermediate products of phenol oxidation overcoming the usual lumping of compounds. The model is composed by several consecutive and parallel reactions. The parameters of the model were adjusted using exper...

Wet Air Oxidation of Waste Water Sludge

Working with Wetox Ltd, a lab scale plant for the continuous oxidation of wastes from municipal water treatment and industrial processes has been developed at IRL using wet air oxidation (WAO). The WAO process can be used to significantly reduce the chemical oxygen demand (COD) of waste sludge and to recover components such as aluminium and phosphate. WAO requires high temperature (240 – 300 °C...

Modelling the Kinetic of UV Water Disinfection

Ultraviolet disinfection is an attractive tool for treating water and eliminating pathogens with safe and available technology especially in developing countries where waterborne diseases cause the death of thousands of people every year. Even though UV is an easy tool to perform disinfection, concerns over the potential of microorganism reactivation constitute an issue for its development. In ...
