“…The SO2 conversion into sulfuric acid in the Earth's atmopshere includes two stages [16,[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. The first stage is the sulfur dioxide oxidation to sulfur trioxide [16,[24][25][26][27][28][29][30][31][32][33][34][35][36].…”

“…The second stage is the sulfur trioxide hydrolysis to sulfuric acid [37][38][39][40][41][42]. The conversion of SO2 into SO3 and H2SO4 has been investigated using experimental and theoretical methods in the past [16,[24][25][26][27][28][29][30][31][32][33][34][35][36]. For example, the reviews of experiments relevant to the gas-phase conversion SO2 into the sulfuric acid has been presented in [16,30].…”

“…Starik with co-workers have investigated the concentrations of sulfate aerosol precursors and chemiions in the aircraft engines using advanced numerical models [34]. Ozone injection methods used to simultaneously remove NOx and SO2 in the flue gas have been investigated by Mok and Lee [35,36]. Davis with co-workers [32] have employed stop-flow time-of-flight mass spectrometry to study the reaction of SO2 and O3 and obtained the rate constant of 2 × 10 at 300 K for the same reaction.…”

“…Therefore the performance of NO oxidation with ozone is important, because NO x cannot be effectively captured in an absorber without conversion of NO into higher oxides. Currently numerous publications describing chemical process of nitrogen monoxide oxidation with ozone are available (Jakubiak and Kordylewski, 2011;Jaroszyńska-Wolińska, 2009;Mok and Lee, 2006;Nelo et al, 1997;Puri, 1995;Skalska et al, 2011;Wang et al, 2006).…”

A process capable of NO x control by ozone injection gained wide attention as a possible alternative to proven post combustion technologies such as selective catalytic (and non-catalytic) reduction. The purpose of the work was to develop a numerical model of NO oxidation with O 3 that would be capable of providing guidelines for process optimisation during different design stages. A Computational Fluid Dynamics code was used to simulate turbulent reacting flow. In order to reduce computation expense a 11-step global NO -O 3 reaction mechanism was implemented into the code. Model performance was verified by the experiment in a tubular flow reactor for two injection nozzle configurations and for two O 3 /NO ratios of molar fluxe. The objective of this work was to estimate the applicability of a simplified homogeneous reaction mechanism in reactive turbulent flow simulation. Quantitative conformity was not completely satisfying for all examined cases, but the final effect of NO oxidation was predicted correctly at the reactor outlet.

With the acceleration of industrialization and the increasing prominence of environmental pollution problems, the emission of nitrogen oxides (NOx) in the atmosphere has become a global concern. These emissions are not only hazardous to human health, but also one of the main factors leading to acid rain, photochemical smog and global climate change. Therefore, the development and implementation of efficient denitrification technologies are an important issue for environmental protection. The present review focuses on the research progress of the denitrification technology in the recent years, including the traditional denitrification methods and common technologies. At the same time, the advantages, limitations and application prospects of each method are analyzed. The mechanisms, influencing factors, advantages and disadvantages of the denitrification catalysts are also discussed. In addition, the future research trends and potential challenges of denitrification technology are discussed. It is expected that this review will provide useful references for promoting the development and application of denitrification technology, which may help researchers to choose high‐performance and cost‐effective methods.
