Transesterification process of Moringa oleifera oil to biodiesel

Transesterification process of Moringa oleifera oil to biodiesel

Biodiesel has become one of the leading options to replace fossil fuels as a source of energy. However, biodiesel production traditionally uses edible plants as it has high acid values, which in turn produce high quality oil. Moreover, current methods of producing biodiesel generate toxic waste as a...

description Biodiesel has become one of the leading options to replace fossil fuels as a source of energy.
