A study has been made of the equilibrium conditions in the reaction between hydrogen gas and dilute solutions of sulphur in liquid iron-carbon alloys. The equation for the reaction may be written as follows: S (in liquid Fe-C alloy) + H 2 (gas) = H 2 S (gas).The carbon content of...
Microbial life below the seafloor has changed over geological time, but these changes are often not obvious, as they are not recorded in the sediment. Sulphur (S) isotope values in pyrite extracted from a Plio- to Holocene sequence of the Peru Margin (Oc
IntroductionHeteroatom oxidation of sulfides to yield sulfoxides is among the most common and facile metabolic steps in eukaryotic and prokaryotic organisms.1–22This reaction has been catalysed by a range of enzyme systems includin... DR Boyd - 《Organic & Biomolecular Chemistry》 被引量: 0发表:...
Sulphur-doped carbon was synthesized using a thiophene-based twin monomer. While tetra(thiophene-2-ylmethoxy)-silane can be converted into sulphur containing nanocomposites, which lead to microporous sulphur-doped carbon, it is possible to produce additional mesopores by the use of templates. Thus, ...
Carbon disulfide is manufactured by heating sulfur vapor with charcoal, and condensing vapors of the compound formed. Alternatively, it may be obtained by heating sulfur with natural gas or petroleum fractions. Instead of sulfur, H2S may be used. The reaction occurs at very high temperatures. The...
Heterogeneous reactions of sulphur dioxide and ja:math mixtures with a carbon soot aerosol 来自 Semantic Scholar 喜欢 0 阅读量: 47 作者:LG Britton,AG Clarke 摘要: The surface reaction rates of SO 2 and SO 2 NO 2 mixtures with a freshly generated carbon soot aerosol have been measured at ...
A study of catalytic reactions of sulphur dioxide and carbon monoxide on perovskite-type compounds of the formula La(1-x)Sr(x)CoO3. This work investigates the use of the perovskite-type compound La1-xSrxCoO3 (x = 0.3, 0.5, 0.6, 0.7) as a catalyst for the reaction1SO2 + 2CO > x...
The carbon framework not only acts as an electronic conduit to the active mass encapsulated within, but also serves as a minielectrochemical reaction chamber. The entrapment ensures that a more complete redox process takes place, and results in enhanced utilization of the active sulphur material. ...
The corrosion behaviour of carbon steel in wet elemental sulphur under both aerobic and anaerobic conditions is reported. The corrosion reaction was studied as a function of the initial pH of the system and the particle size of sulphur. Catastrophic corrosion is observed after an induction period ...
