Abstract

The objective of this research is to study optimization for biodiesel production from transesterification with electric fields. The catalyst in this reaction is potassium hydroxide (KOH) at 1% weight (wt). The molar ratio is 6:1. Two factors at three levels are considered using the response surface method. The first factor, the intensity of the electric field, is set at 85 volts/centimeter (V/cm), 170 V/cm, and 255 V/cm. The second factor, the retention time of the electric fields, is set at 2 minutes (min), 6 min, and 10 min. In the experiments, the best yields are produced from an electric fields intensity of 85 V/cm, with the electric field’s retention time of 2 min. The calculated and experimental results are 98.26% and 98.41%, respectively.
