In this study, biodiesel production process of oil transesterification was designed with the ultrasonic induction. The ultrasonic induction enforced improving the transesterification process. Ultrasonic induction results in molecular activation effects in the reaction medium. Because the excited molecular motion has the heating effects of reaction medium, then the temperature of reactor increased. It makes to increase rate of reaction because of improving mixed effect by high pressure and heating effects. The experimental variable was ultrasonic intensity from 50 to 90 percent in 300, 360, 420, 480, 540W. And biodiesel's production yield was estimated with 5, 10, 15, 20, 25 min interval. |
