Biodiesel Production Using CaO/Fe۳O۴ Nanocatalysts Derived from Shrimp Shells

In this study, a CaO/Fe۳O۴ nanocomposite catalyst was synthesized using shrimp shells for biodiesel production from cooking oil. The effects of different Fe۳O۴ percentages (۳%, ۵%, and ۷%) on the catalyst performance were evaluated under fixed reaction conditions, including a temperature of ۶۲°C, reaction time of ۳ hours, a methanol-to-oil molar ratio of ۱۲:۱, a frequency of ۴۵ kHz, and a catalyst loading of ۳ wt%, under ultrasonic waves. The results indicated that the catalyst with ۳% Fe۳O۴ achieved the highest biodiesel yield (۸۸%), while higher Fe۳O۴ contents resulted in reduced yields. This study demonstrates that the CaO/Fe۳O۴ nanocatalyst with ۳% Fe۳O۴ is an efficient and cost-effective option for biodiesel production and underscores the importance of optimizing process parameters.
