In this paper, palm olein oil was used to produce biodiesel by reducing the percentage of free fatty acids in the oil and then performing a transesterification reaction. biodiesel is one of the sources of alternative fuels. Palm olein oil had treated with sulfuric acid as a catalyst at a ratio of 0.25 wt%. The reaction took place at a methanol-to-oil molar ratio of 3:1 at a temperature of 60 °C and stirred to 250 rpm and for 60 minutes after that, the methanol had separated from the oil. This process reduced the free fatty acid plant by 5%. The transesterification reaction was done by placing 50g of palm olein oil and the reaction had carried out with a methanol-to-oil molar ratio of 6:1, and the catalyst was 1wt%, where the reaction occurred at a temperature of 60 °C for 120 minutes and stirred at 300 rpm. The results of the produced 44.87g of biodiesel and12.34g of glycerin. Test showed an increase in dynamic viscosity, higher biodiesel density, lower calorific value, higher flashpoint, and a higher cetane number compared to fossil diesel. |
