UV/ H2O2 Advanced Oxidation Process for Simultaneous Removal of NO and SO2: A Review

This study presents a review on advanced oxidation processes (AOP) for simultaneous removal of NO and SO2. AOP is based on using a strong oxidant such as ozone and H2O2 which is able to generate highly reactive intermediates. The pollutant will be oxidized and removed by these intermediates. In recent years, AOP has been considered as an effective and attractive technology in the field of flue ...

A Global Climatology of O2⋅O2, O2⋅N2, and (H2O)2 Abundance and Absorption

Recent experimental and theoretical results show that the collision pairs, O2⋅O2 and O2⋅N2, absorb a small but significant fraction of the globally incident, solar radiation (Pfeilsticker et al. 1997, Solomon et al. 1998, Mlawer et al. 1998). The contribution of the water vapor dimer to shortwave (SW) absorption, however, remains speculative due to uncertainties in both its abundance and its ab...

Measurements of HONO, NO, NOy and SO2 in aircraft exhaust plumes at cruise

[1] Measurements of gaseous nitrogen and sulfur oxide emissions in young aircraft exhaust plumes give insight into chemical oxidation processes inside aircraft engines. Particularly, the OH‐induced formation of nitrous acid (HONO) from nitrogen oxide (NO) and sulfuric acid (H2SO4) from sulfur dioxide (SO2) inside the turbine which is highly uncertain, need detailed analysis to address the clima...

The effect of H2O on the reduction of SO2 and NO by CO on La2O2S

The effect of H2O on the catalytic reduction of SO2 and NO on La2O2S was studied using temperature-programmed reaction coupled with fast mass spectrometry, powder X-ray diffraction and X-ray photoelectron spectroscopy. It is found that La2O2S can be completely and irreversibly deactivated in the presence of H2O at 700°C when NO/SO2 is sufficiently high (~1.0). This is caused by the formation of...
