【 摘 要 】

The depleting reserves of petroleum and attendant environmental issues haveled to the search for more eco - friendly and renewable fuels. Biodiesel obtained fromvarious renewable sources have been recognized as one of the alternative fuels due to itsbiodegradability, high cetane number, no sulphur emissions and low volatility. In this paper,biodiesel was obtained from waste frying oil (WFO) by esterification to reduce the free fattyacid (FFA) content (determined by standard titration methods) and then transesterified usingbase catalyzed transesterification method. The WFO had an FFA content of 11.3%. TheWFO was esterified hourly (1, 2, 3, 4) for reduction in %FFA until about < 1% FFA wasachieved prior to transesterification. The esterified oil was transesterified in batches toestablish optimum conditions for the reaction by varying; time, temperature, stirring speedand methanol to oil molar ratio respectively. The methyl ester yield from the efficient basedcatalyzed transesterification of WFO were found to be 50oC, 6:1 methanol-to-oil molar ratio,1% w/v catalyst concentration and a reaction time duration of 40 minutes, 96% optimum yieldand the result of the FTIR analysis confirms the formation of methyl ester having wavelengthof absorption at 2959.475nm, 2784.153nm, 1747.191 and 1469.005 respectively. The fuelproperties of the methyl ester produced were compared with set ASTM standards and werefound to be in line with the standards.
