Elemental sulfur (S(0)) is an important intermediate in the biogeochemical cycle of sulfur that is formed by chemical or biological oxidation of more reduced sulfur species. Given the restricted geochemical conditions under which S(0) should persist, the mechanisms whereby S(0) can be stabilized...
Hydrogen plays a particularly important role in acid–base reactions because these reactions usually involve the exchange of protons between soluble molecules. In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) where it is known as a hydride, or as a positively...
The densities of the planets can be divided into two broad categories: Planets with a density consistent with an Earth-like composition (30% metallic core, 70% silicate mantle) and planets where the density is consistent more with a Mercury-like composition (70% metallic core, 30% silicate ma...
The elemental sulfur reaction can utilize lower hydrogen content gases to drive the reaction compared to the HDS reaction and if used in a recycle arrangement the H2S can be removed from the loop and the majority of the hydrogen in the loop recycled. If reformate gases are used as the ...

3.1. Deacon Reaction Because of the importance of the halogen species, it is proposed that the Hgel oxidation in flue gases could be enhanced by chlorine atoms (Cl•) or molecules (Cl2) produced by the Deacon reaction [14]. Vosteen et al. [15,16] pointed out that the bromine species...
