Experiments and kinetic modeling simulationART-2021-126373The present work is focused on the analysis of the ammonia oxidation process and the formation of main nitrogen oxides (NO, NO2 and N2O) over a wide range of temperatures and O2 reaction environments. Experiments are performed at atmospheric pressure in a laboratory quartz tubular flow reactor, covering the temperature range of 875 to 1450 K and for different air excess ratios (from pyrolysis to very oxidizing conditions). The experimental results are simulated and interpreted in terms of a detailed chemical-kinetic mechanism. Reaction path and sensitivity analyses are used to delineate the NH3 oxidation scheme.2021http://zaguan.unizar.es/record/15131410.1016/j.fuel.2021.120979http://zaguan.unizar.es/record/151314oai:zaguan.unizar.es:151314info:eu-repo/grantAgreement/ES/DGA-FEDER/E22-17Rinfo:eu-repo/grantAgreement/ES/MCIU-FEDER/RTI2018-098856-B-100Fuel 300 (2021), 120979 [7 pp.]by-nc-ndhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.esinfo:eu-repo/semantics/openAccess
