Abstract

This paper presents the effect of high blending ratio (HBR) biodiesel storage on the acid value and flash point temperature. The samples used, standard diesel (STD), B80, B90 and B100 were stored at temperature24 ˚C for nine weeks in a box. The acid value and flash point temperature were measured according to the American Society for Testing and Materials (ASTM) procedure. The results show that, the acid value and flash point temperature of the samples were increased almost 10% with the rise of10% biodiesel blending ratio. Under long storage duration, the acid value and flash point temperature for all the samples are nearest to constant. Consequently, there are no significant effect to the acid value and flash point temperature when all the samples were stored in the dark place at room temperature (24˚C) for long period.
