- Abstract
One of the important factors in biodiesel production is a catalyst. The purpose of this research is to characterize sulfated montmorillonite and its application as catalyst for synthesis of biodiesel from waste cooking oil. Synthesis of sulfated montmorillonite using sulfuric acid as activator and its characterization were performed by using X-Ray Diffraction (XRD), and FTIR analysis. Biodiesel synthesis was carried out by reacting methanol and waste cooking oil with a molar ratio (1: 9) and 1.74 g of catalyst at 65oC for 2 hours. The percentage of methyl ester was analyzed by Gas Chromatography-Mass Spectrometer (GC-MS). Based on XRD analysis data, the addition of sulfuric acid (H2SO4) to montmorillonite does not change the basal spacing d001 on the diffractogram but occurs slight shift toward higher angle (2θ). The FTIR analysis results of sulfated montmorillonite show that the sulfated montmorillonite has functional groups, namely –OH, ≡Si-O-Si≡, Al-Al-OH in the tetrahedral and octahedral sheet structures which are the constituents of the mineral montmorillonite. The percentage of methyl ester produced by sulfated montmorillonite were 6.83% methyl palmitate and 24.17% methyl oleate. Based on the results, it can be concluded that sulfated montmorillonite can be used as catalyst for synthesis of biodiesel.
