Abstract
The compositions of saturated and unsaturated fatty acids in biodiesel feedstocks are important factors for biodiesel properties including low-temperature fluidity and oxidative stability. This study was conducted to improve low-temperature fluidity of biodiesel by reducing total saturated FAME (fatty acid methyl ester) in animal fat biodiesel fuels via urea-based fractionation and by mixing plant biodiesel fuels (rapeseed-FAME, waste cooking oil-FAME, soybean-FAME, and camellia-FAME) with enriched-polyunsaturated FAME derived from animal fat biodiesel. Our results showed that the reduction of total saturated FAME in animal fat biodiesel lowered CFPP (Cold Filter Plugging Point) to $-15^{\circ}C$. Mixing plant biodiesel fuels with the enriched-polyunsaturated FAME derived from animal fat biodiesel lowered CFPP of blended biodiesel fuels to $-10{\sim}-18^{\circ}C$.
