| Biodiesel is an environmental-friendly substitute for fossil fuel. Research on the production of biodiesel from vegetable oils has concentrated on Jatropha, soybean, palm kernel, sunflower and rapeseed oils with scarce information on groundnut oils. This study focussed on the production of biodiesel from groundnut oil. Oil was mechanically extracted from groundnut seeds that were bought from Sabo market in Ogbomoso, Nigeria. The extracted oil was trans-esterized with ethanol using potassium hydroxide as catalyst in a two-step trans-esterification process to yield ethyl esters and glycerol. The fuel properties of groundnut oil and its ethyl ester were determined according to American Society for Testing Materials (ASTM) standard methods and compared... |
