Abstract
Heterogeneous transesterification of Waste Cooking Palm Oil (WCPO) to biodiesel over ion exchange resin solid acid catalyst, Indion-140 in a batch reactor and the optimization of the process conditions have been investigated. The reaction is conducted under various parameters like temperature in the range of 40 °C–80 °C, catalyst loading in the range of 1 g/cc – 5 g/cc based on volume of reaction mixture and mole ratios of reactants in the range of 1:1 – 1:10. The experimental design of the influencing parameters is modeled by using Central Composite Design (CCD) with Response Surface Methodology (RSM). The experiments are performed as per the combinations of influencing parameters designed by aforementioned CCD methodology. The experimental data used the power law regression in a quadratic model. An ANN was trained on the experimental data. ANOVA is used to test the regression model for biodiesel yield. The maximum biodiesel yield achieved was 86.63 % experimentally, while the model predicted a yield of 79.243 % under optimal conditions.
