Abstract
Biodiesel was successful produced in a microwave irradiation reactor using homogeneous and heterogeneous catalysis. The reaction time was significantly reduced compared to the conventional process. In only one minute of reaction, the methyl ester (FAME) conversion obtained was 98.9% with the homogeneous catalyst and within 15 minutes, the heterogeneous catalysis accomplished 100%. In addition, a heterogeneous catalyst was developed based on wasted eggshells. The results indicated that the eggshells treated with KOH presented great potential to be used for microwave-assisted transesterification reactions of oils. The physico-chemical properties of the catalysts were characterized by XRD and TGA-DTG.
