Abstract:
Despite the environmental friendly properties of biodiesel, its widespread use as an alternative fuel to fossil diesel has been limited by both economic and technical issues. Poor oxidation stability of biodiesel is one of these technical barriers, so the addition of antioxidants is usually required to meet the quality standards for biodiesel commercialization. Sterically hindered phenols are known to be free radical scavenging antioxidants. Such compounds are naturally present in the bio-oil produced in the pyrolysis of lignocellulosic biomass. In this work, the antioxidant potential of lignocellulosic bio-oil has been evaluated after different extraction stages with organic solvents. By incorporating small dosages (< 4 wt. %) of the extracted fractions of bio-oil to biodiesel, the oxidation stability of this latter was clearly improved up to reach the limit defined by the European Standard.
