摘要

<span style="font-family:Verdana;">In the efforts to reduce effects of climate change, biodiesel fuels from plant oils such as </span><i><span style="font-family:Verdana;">Jatropha curcas</span></i><span style="font-family:Verdana;"> have been proposed as alternative fuels which can be used in the transportation sector in diesel engines. The current study investigates the effects of fatty acids composition on fuel properties of biodiesel derived from </span><i><span style="font-family:Verdana;">Jatropha curcas</span></i><span style="font-family:Verdana;"> seeds obtained from selected regions of Botswana. The physicochemical fuel properties investigated include kinematic viscosity, flash point, energy content, density, pour point and cloud point from derived </span><i><span style="font-family:Verdana;">Jatropha curcas</span></i><span style="font-family:Verdana;"> biodiesel. Results of the study showed that </span><i><span style="font-family:Verdana;">Jatropha curcas</span></i><span style="font-family:Verdana;"> biodiesel samples for all regions under review are dominated by unsaturated fatty acids which are desirable for cold flow properties and kinematic viscosity of the biodiesel fuel. The major fatty acids in</span><i><span style="font-family:Verdana;"> Jatropha curcas</span></i><span style="font-family:Verdana;"> biodiesel fuels from all the regions range </span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;">from</span></span></span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;"> 69.00% to 77.81% of unsaturated fatty acids. The overall results conclude that fatty acids composition has influence on the fuel properties of the biodiesel under investigated.</span></span></span>
