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.
