Sintesis Kulit Telur Ayam/Serbuk Besi Menjadi Katalis Cao/Serbuk Besi Untuk Reaksi Transesterifikasi Minyak Sawit Off GradeMenjadi Biodiesel

Biodiesel is a biodegradable and biorenewable fuel. Biodiesel can be produced from off grade palm oil and heterogeneous solid base catalyst. It is expected that by modifying this catalyst, it will improve the performance of the catalyst produced so that it can increase the biodiesel yield. Heterogeneous solid base catalyst by modificated Eggshells through calcination, hydration, dehydration methods with iron powder through impregnation method to load calcium oxide with eggshells as precursor. The catalyst with the highest activity is obtained when the calcination temperature of 900 °C and the calcination time of 2 hours under transesterification reaction conditions of a molar ratio of methanol/oil 10:1, catalyst dosage of 1% by weight, temperature of 70 °C for 2 hours with yield biodiesel results reached 91,72%. CaO, Fe3O4 and Ca(OH)2 materials was found in the catalyst through x-ray diffraction (XRD) analysis with a catalyst alkalinity values of H_ > 9.3 through alkalinity analysis using hammet indicator phenolphthalein. Some methyl ester such as methyl palmitate and methyl oleate was found in the biodiesel through Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Keywords: biodiesel, calcination, calcium oxide, catalysts, iron powder
