|Overview||This patent discloses a process for separation of saturated and unsaturated fatty acids. The unsaturated free fatty acids obtained from this process may be transesterified to form fatty acid alkyl esters for use as a cold-tolerant biodiesel fuel. The process includes, A) saponification or esterification of a blend of long chain saturated and unsaturated fatty acids to form free fatty acids or fatty acid alkyl esters, B) complexing the free fatty acids or alkyl esters with urea and C) separating the urea complexed free fatty acids or fatty acid alkyl esters into a first fraction is enriched with saturated free fatty acids or saturated fatty acid alkyl esters and a second fraction enriched with unsaturated free fatty acids or unsaturated fatty acid alkyl esters.|
