Protection of apricot Biodiesel from Thermal Degradation by using natural antioxidants of Fagopyrum tataricum (L.) Gaertn

The present study aims to improve the oxidation stability of wild apricot kernel oil biodiesel (WAKOB) by using natural antioxidants of Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn). Biodiesel was synthesized at different catalyst (NaOH) concentrations, reaction temperatures, reaction time int...
