SO2 which is usually emitted at high temperature one of the most important air pollutants. It great significance to develop adsorbent with efficiency and low cost. In this work, a series hydrotalcite-like compound-derived CaAlO CaXAlO(X = Ce, Co) were prepared by coprecipitation calcination method, employed as adsorbents for adsorption (700 °C). The structure surface properties these characteri...

Chicken eggshell (ES) is a waste from the food industry with high calcium content produced in substantial quantity very limited recycling. In this study, eco-friendly sorbents raw ES and calcined were tested for sulfur dioxide (SO2) hydrogen sulfide (H2S) removal. The was SO2 H2S adsorption at different particle size, without membrane layer. Raw then subjected to calcination temperatures (800 °...

SO2 emissions lead to various harmful effects on environment and human health. The SO2 emission in China has significant contribution to the global SO2 emission, so it is necessary to employ various methods to study SO2 emissions in China with great details in order to lay the foundation for policymaking to improve environmental conditions in China. Network analysis is used to analyze the SO2 e...

BACKGROUND The proximity of capillaries, arterioles, and venules provides complex spatial relationships that lead to oxygen transfer among microvessels. Although a conceptual image of complex oxygen transfer among microvessels has been hypothesized, in vivo mapping of oxygen saturation (SO2) levels in microvessels had never been performed. METHODS AND RESULTS The oxygen profile of the arterio...

Identifying the main byproducts of SF6 decomposition proves to be an effective strategy for determining nature and severity internal discharge faults in gas-insulated switchgears (GISs). In this research, it was suggested utilize coordination polymer Zr-MOF-808 as a sensor decomposition. This study examined adsorption its products (CF4, CS2, SO2, SO2F2, SOF2) on Zr-MOF-808, utilizing Gaussian16...

We have carried out an ab initio molecular dynamics study on the sulfur dioxide (SO2) solvation in 1-ethyl-3-methylimidazolium thiocyanate for which we have observed that both cations and anions play an essential role in the solvation of SO2. Whereas, the anions tend to form a thiocyanate- and much less often an isothiocyanate-SO2 adduct, the cations create a "cage" around SO2 with those groups...

China continues its strategy of total emissions control (TEC) or total load control for SO2 in the Tenth Five Years (2001~2005). This paper will analyze the status of SO2 TEC in China during the Ninth Five-Years (1996~2000). Based on the results of the analysis and the theory of divisional air resources, this paper will study the target of total SO2 emissions nationwide and its allocation for d...

The oxidation of sulfur dioxide to sulfur trioxide over supported vanadium oxide catalysts occurs as both a primary and secondary reaction in many industrial processes, e.g., the manufacture of sulfuric acid, the selective catalytic reduction of NOx with ammonia and the regeneration of petroleum re®nery cracking catalysts. This paper discusses the fundamental information currently available con...

Coal-fired power plants provided between 45% and 50% of the United States net energy generation in the years between 1999 and 2010 and will continue to be a primary source of electricity into the future. Among the major environmental concerns of coal utilization is the release of mercury (Hg), which was recently regulated by the US EPA in the Mercury and Air Toxics Standards (MATS) ruling in De...

BACKGROUND Inhalation of sulphur dioxide (SO2) provokes bronchoconstriction in asthmatic subjects. Cholinergic mechanisms contribute, but other mechanisms remain undefined. The effect of morphine, an opioid agonist, on the cholinergic component of SO2-induced bronchoconstriction was investigated, and the effect of indomethacin, a cyclooxygenase inhibitor, on SO2-induced bronchoconstriction and ...
