Biodiesel, an alternative renewable fuel made from transesterification of vegetable oil with alcohol, is becoming more readily available for use in blends with conventional diesel fuel for transportation applications. Soybean and Rapeseed are common feedstocks for Biodiesel production in USA and Europe, respectively. However, Asian countries are not self sufficient in edible oil and exploring non-edible seed oils, like Jatropha and Pongamia as biodiesel raw materials. However there is a gestation period of few years before these crops start yielding seeds and oil. On the other hand, South Eastern countries like Malaysia and Thailand have surplus Palm crops. But due to substantial amount of saturated fats in Palm, the Palm biodiesel has poor low temperature properties. In order to exploit the proximity of South Asian and South-East Asian countries, blends of Jatropha and Palm biodiesel have been examined to study their physico-chemical properties and to get an optimum mix of them to achieve better low temperature properties, with improved oxidation stability.
