Activated carbons treated with sulphuric acid: Catalysts for catalytic wet peroxide oxidation

Different liquid phase thermal treatmentswere applied to a commercial activated carbon (Norit ROX 0.8) in order to produce modified activated carbons with varying surface chemistry and increased acidic character. Chemical characterization of the prepared materials includes determination of the point of zero charge and evaluation of the concentration and nature of acidic and basic surface functi...

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...

Catalytic properties of carbon xerogels for wet oxidation of aniline

Wet air oxidation (WAO) is an old process developed in the middle of the XX century, but still the centre of very active and contemporary research especially in what concerns catalyst development. In ideal conditions soluble hydrocarbons can be oxidized in aqueous solution to carbon dioxide and water. Organic pollutants with heteroatoms are more challenging, because they require harsh condition...

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...
