Abstract
The effect of added hydrogen on the appearance of OH and SO2 during the oxidation of hydrogen sulfide has been studied over the temperature range 1735°—2340°K. Although the hydrogen was present in concentrations comparable with the other reactants, the basic features of the hydrogen sulfide oxidation were preserved although the inductlon times for the appearance of SO2 and of OH were reduced and their temperature dependences altered. The hydrogen thus accelerates the H2S/O2 reaction but the oxidation of hydrogen is inhibited by the presence of H2S. These findings are discussed in terms of the competition between molecular species for the various radicals present, using as a basis the mechanisms for the oxidations of hydrogen and of hydrogen sulfide proposed previously.Keywords
