• How is biodiesel extracted from Jatropha?
  • Biodiesel is the main product from Jatropha, which is obtained from the oil derived from its seeds. Oil is typically extracted using cold press or a mechanical expeller. Steam may be used during the process to maximize the recovery. A high-quality oil is one without any free fatty acids (FFA).
  • Why is jatropha oil important for biodiesel production?
  • This allows a greater exposure of kernels to the press tool in order to increase the extraction efficiency. The quality of the Jatropha crude oil is also an important issue since it can affect the quality of the biodiesel production for use in vehicles , .
  • Why do we need to prepare Jatropha seeds before oil extraction?
  • High production of biodiesel is required to cope with the depletion of current energy sources. Hence, a large amount of Jatropha seeds need to be prepared prior to the oil extraction process in order to meet the demand.
  • Can a screw press extract jatropha oil?
  • Beerens presented one of the first systematic studies on the mechanical extraction of Jatropha oil using a screw press ( Beerens, 2007 ). Under the different evaluated conditions, an average oil recovery of 80% was obtained in a single pass process.
