Air cleaning
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;
