WebCommon processes of transforming fats and oils into biodiesel are based on transesterification chemical processes, in which triglycerides in the oil or fat are reacted with alcohols, typically methanol, in order to obtain fatty acid methyl esters (FAME), which constitute the biodiesel. Web14 dec. 2011 · In biodiesel production, the vegetable oil used as raw material for transesterification should be free of water and free fatty acids (FFAs), which may consume catalyst and reduce catalyst efficiency. In this work biodiesel was prepared from acidified oils (AO) through a supercritical methanol route, in which the esterification of FFAs and …
