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. 000075715 536__ $$9info:eu-repo/grantAgreement/ES/DGA/GPT$$9info:eu-repo/grantAgreement/ES/MINECO/BES-2016-076610$$9info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-65226 000075715 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000075715 590__ $$a5.627$$b2019 000075715 591__ $$aENERGY & FUELS$$b22 / 112 = 0.196$$c2019$$dQ1$$eT1 000075715 591__ $$aTHERMODYNAMICS$$b4 / 61 = 0.066$$c2019$$dQ1$$eT1 000075715 591__ $$aENGINEERING, MECHANICAL$$b8 / 130 = 0.062$$c2019$$dQ1$$eT1 000075715 591__ $$aENGINEERING, CHEMICAL$$b17 / 143 = 0.119$$c2019$$dQ1$$eT1 000075715 592__ $$a2.116$$b2019 000075715 593__ $$aChemical Engineering (miscellaneous)$$c2019$$dQ1 000075715 593__ $$aPhysical and Theoretical Chemistry$$c2019$$dQ1 000075715 593__ $$aMechanical Engineering$$c2019$$dQ1 000075715 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000075715 700__ $$0(orcid)0000-0001-7559-9669$$aAbián, María$$uUniversidad de Zaragoza 000075715 700__ $$0(orcid)0000-0001-5426-6486$$aBallester, M.Y.$$uUniversidad de Zaragoza 000075715 700__ $$aMillera, Ángela 000075715 700__ $$0(orcid)0000-0002-5420-0943$$aBilbao, Rafael$$uUniversidad de Zaragoza 000075715 700__ $$0(orcid)0000-0003-4679-5761$$aAlzueta, Uxue$$uUniversidad de Zaragoza 000075715 7102_ $$15005$$2555$$aUniversidad de Zaragoza$$bDpto.
