Production of Biodiesel from Jatropha Curcas: A Review

Biodiesel has received a lot of attention and is gaining popularity as a green alternative to fossil diesel all over the world as fossil diesel have a negative impact on the environment, producing global warming, air pollution, and fossil fuel depletion. One of the most promising alternatives to conventional fossil fuels is the use of liquid fuels such as biodiesel made from Jatropha oil through a transesterification process. Because biodiesel has low emission profiles and environmentally favourable characteristics, as well as being non-toxic and non-flammable, it can readily be used as a substitute for fossil diesel. The generation of biodiesel from jatropha oil is the subject of this study. Biodiesel can be made from both edible and non-edible vegetable oils, as well as animal fat. The extraction of oil, pretreatment, transesterification, and separation processes in the manufacturing process of biodiesel from jatropha seeds are all described in this paper. The qualities of jatropha oil, such as flash point, specific gravity, and boiling point, and the parameters related to the jatropha plant, such as genetics, growth factors, plant nutrition, site parameters, botanical features, flowering and fruiting habits, and ecological requirements, are all studied. Transesterification is the process of reacting alcohol and oil to give biodiesel and glycerol. This process is also affected by some of the parameters, like reaction time, the molar ratio of alcohol and oil, reaction temperature, and moisture content
