Intensification and optimization of biodiesel production using microwave-assisted acid-organo catalyzed transesterification process

M. Athar, S. Zaidi, et al.

This groundbreaking research by Moina Athar, Sadaf Zaidi, and Saeikh Zaffar Hassan explores a microwave-assisted acid-organocatalyzed transesterification process for biodiesel production. The study demonstrates how microwave heating dramatically slashes reaction time, achieving near 100% conversion within just 30 minutes while adhering to ASTM D6751 quality standards.

Abstract

This research investigated the intensification and optimization of biodiesel production using a microwave-assisted acid-organo catalyzed transesterification process. The study aimed to reduce reaction time and achieve high conversions under mild conditions using 4-dodecyl benzene sulfonic acid (DBSA) as an organic acid catalyst. Response surface methodology (RSM) was employed to optimize reaction variables. The results showed that microwave heating significantly reduced reaction time (to 30 min for near 100% conversion) compared to conventional heating. A modified polynomial model accurately predicted biodiesel conversion, highlighting the strong influence of catalyst-to-oil ratio and reaction temperature. The produced biodiesel met ASTM D6751 quality standards.
