Effect of Metal on Stability and Cold Flow Property of Pongamia Biodiesel

Abstract

Due to rise in prices of petroleum product the Indian economy is facing burden on the economic front to meet the fuel supply demand. There is large imbalance between the demand and supply of petroleum products. So the government and various research organizations are working on the development of alternative fuel to diesel. Among the various prospective source of alternative fuel Pongamia oil is being identified as one of the important source of biodiesel production in India. But the poor stability and cold flow property associated with the Pongamia biodiesel make it difficult for using it as alternative fuel to diesel. The storage of biodiesel is the major research area for its long term use. The present paper aims to study the effect of metal on the stability and cold flow property of Pongamia biodiesel. The result of investigation show that stability of various metal varies in order of Iron> Aluminium> Zinc while all these material deteriorate the cold flow property of Pongamia biodiesel and make it unsuitable for its long term use.
