相当于用NO2作为催化剂,O2将SO2氧化为SO3,这是过去工业上制取硫酸的一种重要方法的基本原理,叫做“铅室法制硫酸”。 但实际上,真正的反应要复杂一些,部分NO2与SO2反应后,生成NO和SO3,那么只要混合气体不十分干燥,也就是混有水蒸气,就会发生下列反应:
SO2/NO2 Separation Driven by NO2 Dimerization on SSZ-13 …
2022年4月6日 · Herein, we report a NO 2 dimerization facilitated high performance SO 2 /NO 2 separation on a SSZ-13 zeolite membrane. The NO 2 dimerization is triggered by temperature and pressure to form N 2 O 4 with big molecular size, and N 2 O 4 diffusion into the zeolite pore is inhibited on the basis of size exclusion, leading to high separation ...
Fast sulfate formation from oxidation of SO2 by NO2 and HONO ... - Nature
2020年6月5日 · Here we show evidence from field observations of a haze event that rapid oxidation of SO 2 by nitrogen dioxide (NO 2) and nitrous acid (HONO) takes place, the latter producing nitrous oxide...
Oxidation of sulfur dioxide by nitrogen dioxide accelerated at …
2021年9月30日 · Our results indicate that oxidation of SO 2 by NO 2 at aerosol surfaces may be an important source of sulfate aerosols under polluted haze conditions. Atmospheric sulfate aerosol formation from...
Sulfate formation through copper-catalyzed SO2 oxidation by NO2 …
2025年2月18日 · Here, using an aerosol optical tweezer and Raman spectroscopy, we show that the multiphase SO2 oxidation by NO2 is accelerated for two-order-of-magnitude by a copper catalyst.
Separation of SO2 and NO2 with the Zeolite Membrane: …
2022年2月22日 · The separation of NO 2 and SO 2 is a key process step to enable practical deployment. This work proposes SO 2 separation from NO 2 using chabazite zeolite (SSZ-13) membranes and provides insights into the feasibility and advantages of this process using molecular simulation.
Synergistic reaction between SO2 and NO2 on mineral oxides: a …
A new sulfate formation pathway via synergistic reactions between SO 2 and NO 2 on mineral oxides was proposed. The heterogeneous reactions of SO 2 and NO 2 on CaO, α-Fe 2 O 3, ZnO, MgO, α-Al 2 O 3, TiO 2, and SiO 2 were investigated by in situ Diffuse Reflectance Infrared Fourier Transform Spectroscopy (in situ DRIFTS) at ambient temperature.
Synergistic Reaction of SO2 with NO2 in Presence of H2O and …
In this paper, we researched the gas-phase reaction of SO 2 with NO 2 using the density functional theory (DFT) method. The different number of water molecules is added to the reaction so as to investigate the role of water molecules in the oxidation reaction. In addition, the effect of NH 3 in the oxidation reaction also is considered. 2.
