Process intensification of biodiesel production catalyzed by low-cost liquid lipase using ultrasound technology

This research investigates a more efficient method for biodiesel production using low-cost liquid lipase and ultrasound technology. It addresses critical challenges, such as high enzyme costs and low reaction reaction efficiency. By optimizing ultrasound parameters, the research demonstrates improved reaction rates while maintaining enzyme activity. The addition of additives such as sorbitol and ionic liquid DACARB could enhance enzyme stability, further increase biodiesel yield and reduce reaction time. A biodiesel content of 91.3 wt% is achieved within 12 h, using only 0.2 wt% of enzyme. This approach offers a cost-effective and sustainable solution for biodiesel production.
