Production and characterization of biodiesel from coconut extract (Cocos nucifera)
Languages of publication
Oil was extracted from coconut. The extracted oil was used to produce biodiesel and the oil and the biodiesel produced were characterised. Biodiesel are alternative diesel fuels usually obtained from renewable sources, mainly, vegetable and animal oils. Oil was extracted from coconuts bought from a local market in Wukari Taraba State, Nigeria, by solvent method. The extracted coconut oil was characterized. Results obtained showed that the coconut oil has density 0.91 g, viscosity 23mm2/s, saponification value 191 mg KOH/g, iodine value 10 mgl2/g, acid value 14.0 mg KOH/g and flash point 266 °C. Biodiesel of the oil was produced using transesterification process. The biodiesel was also characterized. Results obtained showed that the biodiesel has density 0.89 g, viscosity 2.83 mm2/s, acid value 0.18 mg KOH/g, saponification value 91 mg KOH/g, iodine value 8 mgl2/g, acid value 0.18 mg KOH/g and flash point 110 °C. The physicochemical properties of the biodiesel produce from coconut oil is compared with that of the standard biodiesel in the range of ASTM specifications.
