The current socio-economic, political and environmental challenges of fossil fuels led to alternative energy sources of bio-fuels like biogas, bio-alcohol, biodiesel etc which are sustainable, renewable and environmentally friendly. Neem biodiesel production involved oil extraction from the seed, moisture/FFA reduction then base transesterification reaction using the oil extracted, methanol (6:1), 1.0% KOH at 60oC, 400 rpm for 2 hours. The physico-chemical and fuel properties of the Neem seed oil biodiesel was analysed using standard analytical methods, and the data statistically using SPSS version 20.0. Most parametric values of the biodiesel were within the ASTM/EN standards except in the oil that requires some pretreatment. This biodiesel can be a major contribution now and in the future by meeting the petroleum diesel expected demand. As a result of this, it can be applied in diesel engines, plants with little or no modification and can also extend the life of diesel engines due to its more lubricating property. Read full PDF
