摘要

Synthesizing a biodiesel from natural lipid source containing lipids, comprises introducing the natural lipid source in an enclosure, rapidly heating the natural lipid source at a temperature (To), by water vapor to a total pressure (Po), for a treatment time (tr), successively making a relaxation to a pressure lowered by instant controlled relaxation to texture the natural lipid source and performing an in-situ transesterification to convert at least a portion of lipid contained in the natural lipid source in esters. Independent claims are included for: (1) use of microalgae as natural lipid source for carrying out the above method; and (2) the biodiesel obtained by the above method.
