Abstract
Biodiesel produced from triglyceride which is main component of animal fats and vegetable oils by methanolysis was known for remarkable cetane number. In this study, the derived cetane number of 3 kinds of biodiesel came from vegetable oils such as soybean oil, palm oil, and perilla oil and 2 kind of biodiesel which were produced from beef tallow and pork lard were analyzed using IQT (Ignition quality tester). In IQT test result, the derived cetane number of palm- , beef tallow- and pork lard's biodiesel were more excellent than other biodiesels. After analysis of biodiesel composed molecular by gas chromatography-mass and determination of the derived cetane number of pure biodiesel components using IQT, we have found that the low olefin contented and long alkyl chained biodiesel have excellent derived cetane number.
