Due to the environmental problems caused by the use of fossil fuels, considerable attention has been given to biodiesel production as an alternative to petrol diesel. Biodiesel is ecofriendly, alternative diesel fuel prepared from domestic renewable sources that is, from vegetable oils and animal fats. It is a renewable source of energy which seems to be an ideal solution for global energy demand. In this study, the biodiesel production from kapok (Ceiba pentandra) seed oil with methanol has been considered in the presence of catalyst that is, CaO derived from snail shell. Optimum yield conditions were determined experimentally by changing certain parameters such as reaction time and temperature, at the end of the experiment, the maximum yield of 56.7 % was obtained at 60°C and reaction time of 60 minutes. The physicochemical properties of the produced biodiesel were determined by ASTM procedures and were found to be comparable to ASTM standards for diesel fuel except for acid value which was above the recommended standard. Gas Chromatography-Mass Spectroscopy (GC-MS) demonstrated the presence of hydrocarbons. |
