Polycyclic aromatic hydrocarbons (PAHs) and soot formation in the pyrolysis of the butanol isomers 2017 Access copy available to the general public Unrestricted The formation of polycyclic aromatic hydrocarbons (PAHs) and soot from the pyrolysis of the four butanol isomers: 1-butanol, 2-butanol, iso-butanol and tert-butanol, at three reaction temperatures (1275, 1375 and 1475 K) has been studied. The identification and quantification of the sixteen PAHs, classified by the Environmental Protection Agency (EPA) as priority pollutants, were done using the gas chromatography–mass spectrometry (GC–MS) technique. The soot formed was collected at the reactor outlet. Light gases formed were also quantified. The harmful potential of the PAHs through the benzoa]pyrene equivalent, Ba]P-eq amount, has been evaluated. The main results show that the highest formation of light gases was obtained from the pyrolysis of iso-butanol at 1275 K. The formation of H2 increases significantly as the temperature increases, following the Hydrogen abstraction carbon addition (HACA) route that leads to form PAHs which subsequently form soot. The tendency to soot formation, under the experimental conditions of the present study, is ranked as follows: tert-butanol, 2-butanol, 1-butanol and iso-butanol. The highest PAHs amount and the highest toxic potential, expressed as Ba]P-eq amount, were found in the pyrolysis of all butanol isomers at 1275 K. info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-65226 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 654623-WASTE2FUELS info:eu-repo/grantAgreement/EC/H2020/654623/EU/Sustainable production of next generation biofuels from waste streams/WASTE2FUELS info:eu-repo/grantAgreement/ES/DGA/GPT info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.908 2017 ENGINEERING, CHEMICAL 13 / 137 = 0.095 2017 Q1 T1 ENERGY & FUELS 19 / 97 = 0.196 2017 Q1 T1 1.891 2017 Chemical Engineering (miscellaneous) 2017 Q1 Organic Chemistry 2017 Q1 Fuel Technology 2017 Q1 Energy Engineering and Power Technology 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Gracia, S.
