The influences of oxidative variables on the various property of palm biodiesel were investigated experimentally in this study. Biodiesel, which is composed of mono alkyl esters of long-chain fatty acids, generally has an inferior oxidative stability than petroleum diesel. Hence, the long term oxidative stability of palm biodiesel has received much industry attention because it is used widely as an alternative to pure diesel fuel. Palm biodiesel and its various blends were stored in an atmospheric condition continuously for 1344 h to observe the variation in its oxidative degradation of property. Such as calorific value, kinematic viscosity, density and Flash point. The experimental results reveal that the palm biodiesel suffered greater oxidative degradation and in the absence of an antioxidant, which resulted in a faster decrease in the amount calorific value as the storage time elapsed. The oxidative stability of the palm biodiesel was worst at a longer storage time, which caused the more extensive formation of sediments of oxidative products and hence a larger carbon residue after burning. The greater oxidative degradation also caused the more extensive decomposition of unsaturated fatty acids into oxidative products, which decreased the flash point, kinematic viscosity, density and cloud point the of the.
