Wet Air Oxidation and Catalytic Wet Air Oxidation for Refinery Spent Caustics Degradation
The work focuses on evaluating wet air oxidation and catalytic wet air oxidation technique to degrade refinery spent caustics (original COD is 250,781 mg/L) in a milder operation conditions (150-200 ̊C, 0.2-2.5MPa). The results show that: in non-catalyst WAO, the highest COD degradation conversion could reach about 75% when 200 ̊C, 2MPa oxygen and 300rpm were used. At every temperature, the react...
متن کاملWet 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...
متن کاملDegradation of paracetamol by catalytic wet air oxidation and sequential adsorption - Catalytic wet air oxidation on activated carbons.
The concern about the fate of pharmaceutical products has raised owing to the increasing contamination of rivers, lakes and groundwater. The aim of this paper is to evaluate two different processes for paracetamol removal. The catalytic wet air oxidation (CWAO) of paracetamol on activated carbon was investigated both as a water treatment technique using an autoclave reactor and as a regenerativ...
متن کاملWet air oxidation of phenol using active carbon as catalyst
Catalytic wet air oxidation is a promising alternative for the treatment of phenolic waste water which cannot be treated in conventional sewage plants. Catalytic wet air oxidation of an aqueous phenol solution was conducted in a ®xed bed reactor operating in trickle ̄ow regime. Either active carbon or a commercial copper oxide supported over -alumina was used as catalyst. The performance of bot...
متن کاملBimetallic catalysts for continuous catalytic wet air oxidation of phenol.
Catalytic wet oxidation has proved to be effective at eliminating hazardous organic compounds, such as phenol, from waste waters. However, the lack of active long-life oxidation catalysts which can perform in aqueous phase is its main drawback. This study explores the ability of bimetallic supported catalysts to oxidize aqueous phenol solutions using air as oxidant. Combinations of 2% of CoO, F...
