TY - JOUR AB - The present study investigates the effectiveness of three commercial synthetic (AO1, AO2 and AO3) and one natural (AO4) antioxidants to improve the oxidation stability of various biodiesel fuels produced from different vegetable oils: soybean methyl ester (SBME), rapeseed methyl ester (RME), high oleic sunflower methyl ester (HOSME) and palm methyl ester (PME) and prepared by two different purification steps, using distilled water and acidified distilled water (0.1 M citric acid solution) wash methods. The results of this study have shown that different biodiesel samples have different levels of oxidative stability. Antioxidants can improve the oxidation stability and the antioxidant effect increases as a function of its concentration.
