臭氧氧化脱硝技术研究进展
Research progress of ozone oxidation denitrification technology
摘要
Abstract
Ozone oxidation denitrification technology first oxidizes NO into water-soluble nitrogen oxides such as NO2and N2O5, followed by absorption process for denitration, which is different from reduction denitration technologies. It has been widely used in NOxemission 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.关键词
