Technical Abstract: Fatty acid methyl esters of lard, beef tallow, and chicken fat were prepared by base-catalyzed transesterification for use as biodiesel fuels. Selected fuel properties of the fat-derived methyl esters were determined and found to meet ASTM specifications. The cold-flow properties of the B100 fat derived fuels were measured. Nitrogen oxide (NOx) emission tests also were conducted with the animal fat-derived esters and compared to soy oil biodiesel as 20 vol% blends in petroleum diesel. In general, the cold temperature properties of the fat-based biodiesel fuels were less desirable than those of soy-based biodiesel. However, the data indicated that all three animal fat-based biodiesel fuels had lower NOx emission levels than did the soy-based biodiesel.
