Biomass and agriculture derived materials are alternative sources of energy for the production of biodiesel. Renewable energy attracts wide attention due to its profound contribution to the ecosystem and its role as a sustainable energy source in substitution to diesel and the other petroleum based fuels. This study was conducted to synthesize biodiesel from Citrillus lantanus seed oil. The oil was extracted and characterized having a yield of 49%, density 0.92 g/cm3, acid value 2 mgKOH/g and viscosity of 26 cSt. The oil was characterized to get a high fuel quality in conformity with the American Standard for Biodiesel Testing Materials (ASTM-D6751) and the European Norm (EN-14214) standards. The experiment was designed and analyzed consisting of 28 number of runs by Response Surface Methodology—RSM technique. Four parameters that were studied and varied are temperature and time of reaction, catalyst concentration and methanol-oil ratio, and. The highest triglyceride conversion of 85% was achieved at 55 0C temperature, 30 mins reaction time, 0.5 g NaOH catalyst concentration, and 1:4 methanol-oil ratio. The optimal operating conditions while maximizing desirability was found to be 59.1 oC, 75min, 1.0 g/g, 1:3 of temperature, reaction time, catalyst loading, and methanol-oil molar ratio respectively to give a corresponding yield of 77.13% of biodiesel. The biodiesel produced was in conformity with ASTM standards.
