According to raising demand and study of biodiesel, I have undertaken studies on stability of biodiesel from tree borne non-edible and edible oil seeds. European biodiesel standard EN-14214 calls for determining oxidation stability at 1100C with a minimum induction time of 6 h by the Rancimat method (EN-14112). Research was conducted to investigate influence of presence of transition metals, likely to be present in the metallurgy of storage tanks and barrels, on oxidation stability of biodiesel and influence of other factors like light and darkness. It was found that influence of metal was detrimental to oxidation stability and catalytic. Even small concentrations of metal contaminants showed nearly same influence on oxidation stability as large amounts. Copper showed strongest detrimental and catalytic effect. The dependence of the oxidation stability on the type of metal showed that the biodiesel storage should be very careful. The effect of light and darkness was also compared.
