Abstract
With the increasing global energy demand and growing emphasis on environmental protection, biodiesel as a renewable clean energy has received widespread attention. This study aims to optimize the biodiesel production process and conduct an economic analysis to improve production efficiency and economic benefits. By thoroughly analyzing the existing transesterification reaction process, ultrasonic-assisted technology and ionic liquid catalysts were introduced, significantly enhancing reaction rate and conversion rate. The experimental design employed response surface methodology to optimize process parameters, determining the optimal reaction temperature at 60°C, methanol-to-oil ratio of 12:1, and catalyst dosage of 3%, under which conditions the conversion rate reached 98.5%. Economic analysis indicated that the new technology reduced production costs by 15% and shortened the investment payback period to less than three years. The innovation lies in the first application of combining ultrasonic technology with ionic liquids in biodiesel production, not only improving product quality but also reducing waste liquid emissions. Additionally, a comprehensive life cycle assessment model was established to fully evaluate environmental impacts. The research results provide theoretical basis and technical support for the industrial production of biodiesel, playing a significant role in promoting the development of new energy industries in China.
