Interpretive Summary:

Technical Abstract: The cold flow properties of biodiesel are an ongoing concern for industry and consumers. Development of new feedstocks often yields lipids with high concentrations of high-melting long-chain saturated fatty acids. Conversion of such lipids to fatty acid methyl esters (FAME) results in biodiesel with high cloud point (CP) and cold filter plugging point (CFPP) values. Measurement of these properties takes time and often requires expensive instrumentations. This study develops saturated chain factors as indices for correlating the cold flow properties of biodiesel (FAME). Results showed that the saturated chain factor indices may be used to calculate the CP and CFPP of biodiesel within 1.2°C, with respect to measured properties. These indices and their associated correlation models offer a cost-effective means for determining the cold flow properties and performance of biodiesel derived from diverse lipid feedstocks.
