NOx removal from the flue gas of oil-fired boiler using a multistage plasma-catalyst hybrid system

Isovaleraldehyde degradation using UV photocatalytic and dielectric barrier discharge reactors, and their combinations

“…4 This generates an electrical breakdown in which the new species create an electronic cascade generating a large number of reactive species (mainly O 2 -, OH˙ and O 3 ) which interact and degrade organic compounds. This approach has gained increasing attention in recent years, and several researchers have studied this technology for use in the removal of nitrogen oxides, sulphur oxides and VOCs [11][12][13][14].…”

Plasma-Based Depollution of Exhausts: Principles, State of the Art and Future Prospects

“…Same technology has also tested for oil fired boilers (Park et al, 2008). Typically the flue gases of these sources contains 200-1,000 ppm NO x , 10-200 ppm hydrocarbons, 200-700 ppm CO, 2-8 % CO 2 , 1-5 % H 2 O and 10-18 % O 2 .…”

“…Use of multiple stages of plasma reactors and catalysts can overcome this limitation and increase of the reduction up to 90 % has been demonstrated in simulated exhaust gases (Tonkyn et al, 2003). Hybrid plasma-catalysis reactor with modular design was recently also tested for removal of NOx in oil-fired boiler (Park et al, 2008). The reactor consisted of four consequent plasma/catalyst modules where catalysts could be either TiO 2 or Pd/ZrO 2 .…”

Synergistic catalytic removal NOX and the mechanism of plasma and hydrocarbon gas

“…So the low temperature plasma technology combined with the catalytic technology can be complementary advantages and further improve the denitration efficiency. 9,10 Denitration research at home and abroad are either confined to the traditional methods such as catalytic reduction, catalytic oxidation, or confined to new methods, plasma denitration, for example. There are few reports that can undertake a comprehensive study of the combination.…”
