Acceleration of trimethylamine removal process under synergistic effect of photocatalytic oxidation and surface discharge plasma reactor
Résumé
Removal of trimethylamine (TMA) from the air is exptl. investigated by combining photocatalysis with a DBD plasma reactor, at ambient temp. and atm. pressure. Many parameters are investigated in this work, such as flowrate, inlet concn., relative humidity of effluent, and specific energy of discharge. By combining non-thermal plasma and photocatalysis, a synergy effect on the removal efficiency of TMA has been obsd. under different exptl. conditions. Moreover, we note that adding a photocatalyst in the zone of plasma inhibits ozone formation. The formation of byproducts due to TMA removal is also studied. The identified and analyzed byproducts are classified into four groups: intermediary products, carbon monoxide, carbon dioxide, and ozone and nitrogen oxides
