The influence on the oxidation process of the oxygen inlet concentration (determined by the air excess ratio, λ) and the amount of ethanol (0-200 ppm) present in the reactant mixture has also been evaluated. In general, the predictions obtained with the proposed model are in satisfactory agreement with the experimental data. For a given pressure, the onset temperature for acetylene conversion is almost the same independent of the oxygen or ethanol concentration in the reactant mixture but is shifted to lower temperatures when the pressure is increased. Under the conditions of this study, the ethanol presence does not modify the main reaction routes for acetylene conversion, with its main effect being the modification of the radical pool composition. info:eu-repo/grantAgreement/ES/DGA/GPT info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-65226 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.021 2018 ENGINEERING, CHEMICAL 46 / 138 = 0.333 2018 Q2 T2 ENERGY & FUELS 52 / 103 = 0.505 2018 Q3 T2 1.035 2018 Chemical Engineering (miscellaneous) 2018 Q1 Fuel Technology 2018 Q1 Energy Engineering and Power Technology 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Fuster, Miguel (orcid)0000-0001-5426-6486 Millera, Ángela Universidad de Zaragoza (orcid)0000-0002-5420-0943 Bilbao, Rafael Universidad de Zaragoza (orcid)0000-0003-4679-5761 Alzueta, María U.
