Optimization by response surface methodology of biodiesel production from Podocarpus falcatus oil as Cameroonian novel non-edible feedstock
Operating conditions for the production of biodiesel
Steps to reproduce
transesterification reaction was carried out in a 100 mL three-necked round-bottomed flask. The device consists of a hot plate fitted with the magnetic stirrer. For each experiment, 50 g of oil Podocarpus falcatus oil was carefully transferred to the flask and preheated to its reaction temperature. After preheating, a solution of potassium methoxide was freshly prepared and added to the preheated oil. The mixture was heated to reflux and with stirring for a specified reaction time and temperature. After the transesterification reaction, the mixture underwent separation in a separating funnel for 6 h. The upper phase containing the biodiesel was washed several times with hot water to remove the catalyst and traces of soap formed during the reaction. After washing, the biodiesel phase was dried in an oven at a temperature of 110 ° C for 4 hours to evaporate the traces of water and methanol.
