Therefore, the addition of antioxidants is usually required to meet the quality standards for biodiesel commercialization. Synthetic sterically-hindered phenols have been usually employed for this purpose as free radical scavenging antioxidants. However, naturally occurring phenolics are also available, for example, in the bio-oil produced in the pyrolysis of lignocellulosic biomass. In this work, the antioxidant potential of extracted fractions of lignocellulosic bio-oil has been evaluated. Different organic solvents were tested as extraction agents, acetate esters being the best ones for incorporating bio-oil antioxidant compounds into biodiesel. In the best case, the incorporation of a small concentration of bio-oil compounds (< 4 wt.%) led to an improvement of the biodiesel oxidation stability of 475% which, in our case, was enough to meet the European standard requirement. info:eu-repo/grantAgreement/ES/DGA/GPT info:eu-repo/grantAgreement/ES/MINECO/ENE2013-41523-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.956 2017 CHEMISTRY, APPLIED 8 / 71 = 0.113 2017 Q1 T1 ENGINEERING, CHEMICAL 21 / 137 = 0.153 2017 Q1 T1 ENERGY & FUELS 29 / 97 = 0.299 2017 Q2 T1 1.453 2017 Chemical Engineering (miscellaneous) 2017 Q1 Fuel Technology 2017 Q1 Energy Engineering and Power Technology 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-8553-265X Botella Abad, Lucía (orcid)0000-0002-8704-9274 Gil-Lalaguna, Noemí (orcid)0000-0002-5959-3168 Arauzo Pérez, Jesús Universidad de Zaragoza (orcid)0000-0001-8960-2689 Gonzalo Callejo, Aberto Universidad de Zaragoza (orcid)0000-0002-9705-2207 Sánchez Cebrián, José Luis Universidad de Zaragoza 5005 555 Universidad de Zaragoza Dpto.
