Beschreibung
Zusammenfassung:	The invention relates to a method for producing biodiesel using supercritical fluid extraction and alcoholysis hulled Jatropha seed. More specifically, the method comprises step of firstly usinga supercritical carbon dioxide extraction process to obtain hulled Jatropha seed oil; then performing sub-critical hydrolysis reaction and supercritical alcoholysis reaction to respectively obtain hydrolysis oil and alcoholysis oil; and transforming the hulled Jatropha seed through the two stage reactions of sub-critical hydrolysis and supercritical alcoholysis reaction, thereby obtaining biodiesel with high purity of 98.5% weight percentage.
