Energy crises, depletion of fossil fuel reservoirs, environmental pollution, global warming, green house effect and starvation are becoming very serious problems in the modern world. Biodiesel is a liquid fuel which can be the best alternative for the fossil fuels. In this study, non-edible rubber seed oil (RSO) with high free fatty acid (FFA) content (45%) was used for the production of biodiesel. The process comprises of two steps, in the first step acid esterification was used to reduce the FFA and in the second step base transesterification was employed to convert the treated oil into rubber seed oil methyl esters (RSOMEs). The conversion yield of biodiesel was analyzed using gas chromatography. The fuel properties were tested using the standard procedure of ASTM D6751 and EN14214. All the properties were within the ranges of the biodiesel standards. The result shows that rubber seed oil is a potential non-edible source for biodiesel production.

Hura Crepitans

Oil was extracted from the seed of Hura crepitans using hexane in a soxhlet extractor and analyzed for iodine value, saponification value and free fatty acid content. The dominant fatty acid in the oil was C18:2 (52.8±0.10%) while the iodine value was 120.10±0.70 g iodine/100 g. Biodiesel was produced from the oil using a two-step reaction system involving a first step of pretreatment via esterification reaction and a second step via transesterification reaction. The pretreatment step showed that free fatty acid in Hura crepitans seed oil can be reduced in a one-step pretreatment of esterification using H2SO4 as catalyst. The biodiesel produced from Hura crepitans seed oil had an acid value of 0.21±0.00 mg KOH/g, flash point of 152 ± 1.10°C, copper strip corrosion value of 1A, calorific value of 39.10±0.30 mJ/kg, cetane number of 45.62±0.30, and density of 0.86±0.02 g cm−3. The process gave a biodiesel yield of 98.70±0.40% with properties within the recommended values of EN 14214.

Depending on composition, fatty acids of plant sources are explicitly useful in food, chemical and pharmaceutical industries. The present study characterizes Soxhlet extracted neem seed oil by determination of physicochemical properties and bioactive compounds. Extraction involved the use of solvent semi-continuous extraction method for 6 hours with N-hexane. Percentage Oil yield was at 39. Saponification value (50.490mgKOH/g), Iodine value (50.28g/100g), Acid value (5.610mgKOH/g), Free fatty acid (2.805w/w), Peroxide value (62.75meq/kg) and Specific gravity (0.948) were determined. Density at 250C, Flash point, boiling point, melting point, colour and Odour provided supportive information to the major physicochemical properties analyzed. Gas Chromatography - Mass Spectrometry (GC-MS) of the Soxhlet extracted Neem Seed oil showed different peak values of industrially essential compounds such as 7-Pentadecyne, Glycidyl palmitate, Oleic Acid, 9,12-Octadecadienoic acid and methyl ester (Omega-6 acid). Saponification value was found to be high, suggesting the presence of FFA with low molecular weight, which brands the oil as essential in cosmetic and food industries. Low Iodine value and low total acidity seems to consolidate the usefulness of neem seed oil in cosmetic industries. Conversely, the high peroxide level makes it unsuitable for cooking. It may therefore be inferred that Soxhlet extracted Azadirachta indica seed may be industrially viable but less suitable for consumption.
