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 کاملCopper on Activated Carbon for Catalytic Wet Air Oxidation
Textile industry is an important source of water contamination. Some of the organic contaminants cannot be eliminated by nature in a reasonable period. Heterogeneous catalytic wet air oxidation is one of the most effective methods to purify wastewater with organic contaminants. In this work, catalysts based on copper supported on activated carbon were synthesized. The activated carbons were obt...
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...
