Abstract

Heterogeneous catalysts in transesterification has been used to biodiesel production because have many advantages. This research aims to synthesize heterogeneous base catalyst Na2O/Fe3O4 which will be used in transesterification reaction for production of biodiesel. Catalyst Na2O/Fe3O4 was synthesized from sodium hydroxide (NaOH) and iron powder using wet impregnation method. The independent variables of this research are molar ratio of WCO/methanol 1:6, 1:8, 1:10, and loading catalyst Na2O/Fe3O4 3%, 4%, 5%-w WCO. These variables are to determine the yield crude biodiesel. Reaction temperature is 60°C (±2) for 2 hours, under stirring 300 rpm. The highest yield of biodiesel is 95.45% under the transesterification methanol/WCO molar ratio 1:10, loading catalyst 3%-w.Keywords: Biodiesel, esterification, catalyst, heterogeneous, transesterification, WCO
