Air cleaning

Catalytic oxidation with cold plasma

Catalytic oxidation with cold plasma

Objective

Treatment of air pollutants, combustion gases, etc. Especially for the oxidation of NOx, CO and VOCs by means of a catalytic bed of metal oxides, the most common being TiO2, which decomposes ozone using plasma and high intensity electric current and generates a current highly reactive ionized to oxidize the compounds to be treated.

Inlets

Gases with polluting compounds that are difficult to oxidize by biological means or under mild oxidation conditions (VOCs are very hydrophobic and difficult to absorb, adsorb and degrade). They can come from industrial sources, combustion, or waste treatment/valorization processes

Efficiency

Oxidation efficiencies >90%

Weaknesses

Need for additional stages of removal of gaseous compounds;
Consumption of expensive catalysts and energy in the form of light;
Generation of complex by-products to characterize;

Products

Oxidized gaseous pollutants (CO2, NO2, SO2, etc.)

Other outlets
