Abstract: The effect of raw material (fatty acid) composition of tung oil methyl ester (TME) and jatropha oil methyl ester (JME) on their fuel properties was investigated. TME and JME contain high amount of unsaturated fatty acids. TME consists of larger amount of elaeostearic acid while JME contains higher amount of oleic and linoleic acids. The quality characteristics of feedstocks were also investigated. The allylic and bis-allylic position equivalents were calculated and related with oxidation stability. The measured properties were compared with EN 14214, ASTM D6751, and IS 15607 standard specifications. Results showed that JME met more of the standard specifications than TME. From the study, it was found that the biodiesel properties are significantly influenced by the fatty acid composition of parent oils. [Received: May 24, 2014; Accepted: November 18, 2014]
