Ozone oxidation denitrification technology first oxidizes NO into water-soluble nitrogen oxides such as NO2 and N2O5

followed by absorption process for denitration

which is different from reduction denitration technologies. It has been widely used in NOx emission control of catalytic cracking and industrial boiler flue gases. The technological characteristics and reaction kinetics of ozone oxidation denitrification technology were discussed

the oxidation selectivities of NO in complex flue gases were analyzed

and the effects of ozone and NO molar ratio

reaction temperature and residence time on the composition of oxidation products were studied. After that

the influence of absorbents

absorption gas compositions and additives on absorption efficiencies was analyzed by elaborating the principle of synergistic absorption of sulfur dioxide and nitrogen oxides in both wet and semi dry desulfurization processes. Based on the above discussion

the deficiencies in the research of ozone oxidation denitration technology were put forward and the future development of this technology was proposed.
