An experimental and modeling study of the oxidation of acetylene (C2H2, considered as an important soot precursor) and DME mixtures has been performed under well-controlled flow reactor conditions. The influence of temperature, air excess ratio (¿) and presence of NO on the oxidation process has been analyzed. Under fuel-rich conditions, the presence of DME in these mixtures modifies the radical pool delaying the acetylene consumption. C2H2 and DME, and the radicals generated in their conversion, interact with NO achieving different levels of NO concentration diminution depending upon the operating conditions. Under fuel-lean conditions, the presence of DME in the mixtures increases the NO diminution, whereas for the other values of ¿ considered, the maximum NO decrease reached is lower than that obtained in the case of pure acetylene. info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-65226 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.601 2016 ENGINEERING, CHEMICAL 13 / 135 = 0.096 2016 Q1 T1 ENERGY & FUELS 16 / 92 = 0.174 2016 Q1 T1 1.736 2016 Chemical Engineering (miscellaneous) 2016 Q1 Organic Chemistry 2016 Q1 Fuel Technology 2016 Q1 Energy Engineering and Power Technology 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Berdusán, Laura Aranda, Verónica (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.
