Biodiesel Production from Jatropha Seed Oil: Chemical Engineering Project

The .Team.9:.Oil.from.[the].Soil project aims to extract seed oil from Jatropha plants and convert it to biodiesel using a two-step process involving extraction and transesterification. The team outlines the original mechanical extraction approach and the revised chemical approach, which includes solvent extraction and transesterification conversion using common chemicals like NaOH and methanol in a batch reactor. They have completed preliminary design work, research, and chosen equipment and chemicals. Future plans involve continuing research, sourcing seeds, chemical ordering, and prototype construction in the upcoming semester.
