Solid liquid extraction of Jatropha seeds by microwave pretreatment and ultrasound assisted methods

Jatropha curcas has a variety of uses which are of great economic significance. Jatropha oil can be used as fuel alternative and for making biodiesel that is supposed to overcome the source limitation problem. In this study, conventional, ultrasound assisted and microwave pretreatment solid liquid e...
