The experiments have been carried out in a tubular flow reactor, in the 700-1400¿K temperature range. The concentrations of H2S, SO2 and H2 have been determined and the experimental results have been simulated with a detailed chemical mechanism compiled in the present work. The experimental results obtained indicate that H2S consumption is shifted to lower temperatures as the stoichiometry increases, starting at 925K for reducing conditions and at 700K for the most oxidizing ones. The model reproduces well, in general, the experimental data from the present work, and those from the literature at high pressures. Supported by theoretical calculations, the isomerization of HSOO to HSO2 has been determined as an alternative and possible pathway to the final product SO2, from the key SH+O2 reaction. info:eu-repo/grantAgreement/ES/DGA/GPT info:eu-repo/grantAgreement/ES/MINECO/BES-2016-076610 info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-65226 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.627 2019 ENERGY & FUELS 22 / 112 = 0.196 2019 Q1 T1 THERMODYNAMICS 4 / 61 = 0.066 2019 Q1 T1 ENGINEERING, MECHANICAL 8 / 130 = 0.062 2019 Q1 T1 ENGINEERING, CHEMICAL 17 / 143 = 0.119 2019 Q1 T1 2.116 2019 Chemical Engineering (miscellaneous) 2019 Q1 Physical and Theoretical Chemistry 2019 Q1 Mechanical Engineering 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-7559-9669 Abián, María Universidad de Zaragoza (orcid)0000-0001-5426-6486 Ballester, M.Y.
