Predicting the Oxidation Stability of Soybean Oil/Coconut Oil Blends as a Function of Feedstock Mass Fraction

摘要

Biodiesel is a cleaner burning, renewable fuel that has noted benefits both in its neat form as well as in blends with diesel, where it adds useful lubricity and other properties. However, a drawback of biodiesel is that after a period of months, significant amounts of peroxides are formed, which cause polymerization in the fuel and may lead to engine damage. Predicting at what point polymerization will occur in storage is performed using accelerated shelf life, or oxidation stability tests.
