Processo de produção de biodiesel etílico em banho ultrassônico utilizando cossolvente: uma revisão sistemática

Abstract

The present study presents a Systematic Literature Review (SLR) based on the PRISMA, multicriteria, and snowball methods, aiming to analyze the application of ultrasonic bath and cosolvent in the production of ethyl biodiesel. The research analyzes the current scientific landscape to identify the main advances, the raw materials employed, and the contribution of both technologies to the reaction, in comparison with traditional transesterification methods. The low miscibility between alcohol and triglycerides acts as the main limiting factor of the process, compromising mass transfer. As an alternative identified in the SLR, different cosolvents proved capable of increasing the homogenization of the reaction system, reducing reaction time, and increasing biodiesel yield. It was concluded that the combination of ultrasonic bath and cosolvent remains scarcely explored in the literature, indicating an opportunity for expanding future research focused on the development of more efficient and sustainable routes for biodiesel production.
