The impact of temperature, pressure, oxygen stoichiometry and presence of NO has been analyzed on the concentrations of NH3 and N2 obtained as main products of ammonia oxidation. The main results obtained indicate that increasing either pressure or stoichiometry results in a shift of NH3 conversion to lower temperatures. The effect of pressure is particularly significant in the low range of pressures studied. The main product of ammonia oxidation is N2, while NO, NO2 and N2O concentrations are below the detection limit for all the conditions considered. The experimental results are simulated and interpreted in terms of a literature detailed chemical kinetic mechanism, which, in general, predicts satisfactorily the experimental results. 000126803 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/T22-17R$$9info:eu-repo/grantAgreement/ES/MCIU-FEDER/RTI2018-098856-B-100$$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-124032OB-I00$$9info:eu-repo/grantAgreement/ES/MINECO/PRE2019-090162 000126803 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000126803 590__ $$a6.7$$b2023 000126803 592__ $$a1.451$$b2023 000126803 591__ $$aENGINEERING, CHEMICAL$$b23 / 170 = 0.135$$c2023$$dQ1$$eT1 000126803 591__ $$aENERGY & FUELS$$b46 / 171 = 0.269$$c2023$$dQ2$$eT1 000126803 593__ $$aEnergy Engineering and Power Technology$$c2023$$dQ1 000126803 593__ $$aOrganic Chemistry$$c2023$$dQ1 000126803 593__ $$aFuel Technology$$c2023$$dQ1 000126803 593__ $$aChemical Engineering (miscellaneous)$$c2023$$dQ1 000126803 594__ $$a12.8$$b2023 000126803 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126803 700__ $$0(orcid)0000-0002-2126-2232$$aUruén, M.$$uUniversidad de Zaragoza 000126803 700__ $$0(orcid)0000-0001-7559-9669$$aAbián, M.$$uUniversidad de Zaragoza 000126803 700__ $$0(orcid)0000-0003-4679-5761$$aAlzueta, M.U.$$uUniversidad de Zaragoza 000126803 7102_ $$11009$$2773$$aUniversidad de Zaragoza$$bDpto.
