Reduction of sulfur dioxide by carbon monoxide to elemental sulfur over composite oxide catalysts
The catalyst activity of fluorite-type oxide, such as ceria and zirconia, for the reduction of sulfur dioxide by carbon monoxide to elemental sulfur can be significantly promoted by active transition metals, such as copper. More than 95% elemental sulfur yield, corresponding to almost complete sulfur dioxide conversion, was obtained over a Cu-Ce-O oxide catalyst with a feed gas of stoichiometri...
متن کاملSelective catalytic reduction of sulfur dioxide by carbon monoxide over iron oxide supported on activated carbon
The selective reduction of sulfur dioxide with carbon monoxide to elemental sulfur was studied over ACsupported transition-metal oxide catalysts. According to the study, Fe2O3 /AC was the most active catalyst among the 4 AC-supported catalysts tested. By using Fe2O3 /AC, the best catalyst, when the feed conditions were properly optimized (CO/SO2 molar ratio = 2:1; sulfidation temperature, 400 ◦...
متن کاملThe carbon dioxide leakage from chambers measured using sulfur hexafluoride
In plant chamber studies, if CO2 leaking from a chamber is not quantified, it can lead to an overestimate of assimilation rates and an underestimate of respiration rates; consequently, it is critical that CO2 leakage be determined. Sulfur hexafluoride (SF6) was introduced into the chambers as a tracer gas to estimate leakage rates. Chamber leakage constants were determined by measuring the rate...
متن کاملSulfur Dioxide Internal and External Adsorption on the Single-Walled Carbon Nanotubes: DFT Study
Density-functional theory is used to investigate sulfur dioxide physisorption inside and outside of single-wall carbon nanotube of (5,0) and (5,5). This study is conducted at B3LYP/6-31G* level of theory. Sulfur dioxide molecule is studied with axis oriented parallel or perpendicular to the nanotube wall. Both internal and external adsorption on nanotubes is increased with the angle of interact...
متن کاملSulfur Dioxide
The ubiquity of sulfur dioxide as an air pollutant combined with reports of effects of the gas and its blood metabolite on DNA and chromosomes, prompted a study of possible mutagen action on mammalian oocytes. Utilizing in vitro and in vivo systems, mouse, ewe, and cow oocytes were examined for cytologic evidence of structural or numerical damage in meiosis. Fragmentation with rearrangement see...
