Biodiesel Production from Reutealis trisperma Oil Using Conventional and Ultrasonication through Esterification and Transesterification

The limitation of fossil fuel sources and negative environmental impact persuade scientists around the world to find a solution. One possible solution is by using renewable replace with an inexpensive, fast, effective production process. objective this study investigate biodiesel from crude Reutealis trisperma oil conventional ultrasonic bath stirrer method through esterification transesterification result shows that most reaction time optimum condition for at 2 h 30 min method. conditions temperature 55 °C 60 2% (v/v) sulphuric acid catalyst concentration 0.5 wt.% were methanol-to-oil ratio 60%, agitation speed 1000 rpm. This gives highest yield 95.29% biodiesel. results showed had more effect on needed than reduced half time. Finally, properties fulfilled ASTM D6751 EN 14214 standards density, 892 kg/m3; pour point, ?2 °C; cloud ?1 flash 206.5 calorific value, 40.098 MJ/kg; 0.26 mg KOH/g.
