Copper 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...

Degradation 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...

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...

Influence of textural properties and iron content on the activated carbon performance for catalytic wet air oxidation of phenol

Catalytic Wet Oxidation is a promising treatment for wastewater containing refractory compounds, such as phenol. Activated carbon has demonstrated to perform as catalyst in wet oxidation, however it is not fully understood its role as catalyst. This study aims to clarify the effect of metal content, specifically iron and calcium, on the performance of a commercial activated carbon. Several modi...

Bimetallic 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...
