The study was made using a constant concentration of ethylene and different inlet concentrations of H2S, in a temperature range from 1075 to 1475 K. The light gases produced were quantified by a chromatographic method. The soot amount formed was also quantified at the outlet of the reactor. The speciation of the individual EPA-PAH compounds was made by a combination of Soxhlet extraction, extract concentration by a rotary evaporator, and gas chromatography coupled to mass spectrometry. The present study shows that, under pyrolysis conditions, there is an effective interaction between H2S and hydrocarbons, forming significant amounts of CS2 and bonding sulfur to soot. The presence of H2S in the pyrolysis of ethylene contributes to slightly decrease the formation of soot and EPA- PAH, which indicates a positive effect of the sulfur compound under pyrolysis conditions. info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-65226 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 3.091 2016 ENGINEERING, CHEMICAL 27 / 135 = 0.2 2016 Q1 T1 ENERGY & FUELS 33 / 92 = 0.359 2016 Q2 T2 1.258 2016 Chemical Engineering (miscellaneous) 2016 Q1 Fuel Technology 2016 Q1 Energy Engineering and Power Technology 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sánchez, Adrián (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.
