| dc.description.abstract | The dwindling resources of fossil fuels coupled with the steady increase in energy consumption have encouraged research interest in alternative and renewable energy sources. Biodiesel is one of the most promising alternatives for fossil fuels. To foster market competitiveness for biodiesel, it is necessary to produce biodiesel from economically viable and environmentally sound feed stocks. This study deals with the biodiesel production from tannery solid waste. The tannery solid wastes, from different sections of processing units, have been characterized for their fat content. The investigation proved that it was the fleshing waste which has a potential fat content (23%) to be used as biodiesel feed stock. The fleshing oil converted to free acid methyl ester (FAME) or biodiesel using a two step acid and base catalyzed esterification and transesterification reactions respectively. The effect of oil to alcohol molar ratio, the amount of catalyst and temperature on biodiesel production was investigated using Design Expert 7.0.0 and optimum reaction conditions were determined. The fuel properties of the biodiesel were also studied according to the ASTM standard. The result showed that fleshing oil can be a very viable and commercially competitive biodiesel feed stock even though some of the properties like cloud point needs further improvement. | en_US |
