- Abstract
- The production process of waste oil based biodiesel was introduced in experimental manner. Ultrasonic energy was irradiated to induce the trans-esterification of the waste oil. The ultrasonic irradiation had two effects, those were heating and mixing of the reactants. We performed the experiment under various production parameters, viz., the ultrasonic irradiation time, sonic power, methanol/waste oil mole ratio, and reaction temperature. The optimum condition was determined at an ultrasonic irradiation time = 30 min, sonic power = 500 W, methanol/waste oil mole ratio = 7 when the reaction temperature was 55oC. We suggest that new biodiesel production processes using ultrasonic energy would alter the conventional process of heating and mixing.
