Its ability to resist deactivation by sulfur and coking appears linked to the mixed conductor's enhanced catalytic activity for sulfur oxidation and hydrocarbon cracking and reforming, as well as enhanced water adsorption capability. 展开 关键词: colon cancer min mouse proteomics differential mass ...
However, due to the presence of molecular oxygen, water vapor, metallic materials, and solid insulation materials, SFx further reacts with impurities to form stable by-products (SO2F2, SOF2, SO2, HF, H2S, and other gases) [97]. The formation of major decomposition products is shown in Fig...
Sulfur is mined by the recovery method known as the Frasch process, which was inventedby Herman Frasch in Germany in the early 1900s. This process forces superheated water,under pressure, into deep underground sulfur deposits. Compressed air then forces the moltensulfur to the surface, where it...
Alternatively, homocysteine can be replaced by cysteine or by water, forming lanthionine or serine, respectively, and eliminating H2S [46]. The H2S-forming reactions catalyzed by CBS are discussed in greater detail in Chapter 20. In addition, CBS can catalyze the β-elimination of cystine, ...
sup> dry mass) and the highest calculated inventories of 'excess' sulfur (20–180 g S m−2) are found in southern Sweden and around one industrial area along the northeastern coast where sulfur deposition rates and lake-water concentrations have been highest. For many lakes in the central...
Columns of soil samples were saturated with solutions of 100 meq (NaCl+ CaCl2)L1 with sodium adsorption ratios (SARs) of 5, 10, 15, and 20, and subsequently leached with distilled water. The "Sensitivity Index" or SI concept was used to obtain a very general index of the magnitude of ...
Therefore, it is important that the subducted-slab derived fluids carry significant S and Cl into the mantle wedge, but higher than average initial water concentrations in primitive arc magmas are not favourable for magmatic-hydrothermal ore genesis. Methods...
which proceeds readily in the presence of water vapor. For the complete reduction of sulfur dioxide, however, a large excess of sulfuretted hydrogen is required (H2S:SO2 = 2.2:1). Owing to possible water losses in this case, it is unlikely that the process can be used for the flow refl...
formation of surficial standing liquid water, there are potential sources of liquid water in the Martian subsurface. Recent evidence suggests the presence of hypersaline lakes below Mars’ southern ice cap [13]. Another possible source of liquid water is the recurring slope lineae; recent modeling ...
