Hydrogen sulfide (H2S) and sulfur dioxide (SO2) are two typical decomposition byproducts of hexafluoride (SF6), commonly used as an insulating medium in electrical equipment; for instance, gas circuit breakers insulated switchgears. In our work, fiber-like p-CuO/n-ZnO heterojunction sensing materials were successfully prepared via the electrospinning method to detect SF6 byproducts, H2S SO2 gas...

In this paper, the development of a new potassium carbonateon alumina support sorbent prepared by impregnating K2CO3 with an industrial grade of Al2O3 support was investigated. The CO2 capture capacity was measured using real flue gas with 8% CO2 and 12% H2O in a fixed-bed reactor at a temperature of 65 °C using breakthrough curves. The developed sorbent showed an adsorption capacity of 66.2 mg...

van der Waals cluster (SO2)n is investigated by using single photon ionization of a 26.5 eV soft x-ray laser. During the ionization process, neutral clusters suffer a small fragmentation because almost all energy is taken away by the photoelectron and a small part of the photon energy is deposited into the (SO2)n cluster. The distribution of (SO2)n clusters decreases roughly exponentially with ...

The effect of water vapor on the DeSOx performance regenerable CuO/SBA-15 adsorbent was investigated for different temperatures adsorption/regeneration cycles and CuO loadings. At 400 °C a significant decrease both dynamic total SO2 adsorption capacity compared to ones measured without observed. This could be related faster migration aggregation active phase, an competition between molecules si...

A detailed understanding of the chemical stability metal–organic frameworks (MOFs) in water and acidic basic solutions currently exists; however, there has been comparatively little investigation into MOFs presence acid gas species that may be present industrial settings. MIL-101(Cr), a MOF is stable liquid as well solutions, was tested for its upon exposure to gases sulfur dioxide (SO2) nitrog...

In this work, the interaction of GaN nanotube (GaNNT) with common air pollutants industrialized cities, such as NH3, NO2 and SO2 in different configurations was studied. For study, single-walled (10,0) GaNNT used. The analysis done via density functional theory implemented SIESTA simulation software. results shows that alter properties nanotubes when they interact them. stability most stable ar...
