Abstract

The present study juxtaposes for the first time the heterogeneous methanolysis of gmelina oil over KNO 3 activated MgO-ZnO with a NaOH base methanolysis for biodiesel production. The conditions for biodiesel production such as temperature, reaction time, NaOH (or KNO 3 dose) and methanol-gmelina oil ratio were optimised. The 4%w/w KNO 3 activated MgO-ZnO afforded high biodiesel yield (71.5 %) at 65 o C predominantly consisting of C13-C25 cuts of linear fatty acid methyl esters (FAME). This heterogeneous catalyst was characterized using X-ray diffraction (XRD), energy dispersive X-ray (EDX) analyser, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Gas-chromatography-mass spectrometry (GC-MS) revealed the selectivity to petroselinic acid methyl est er. The fuel properties of the biodiesel and its blends were consistent with standards. Relatively, the NaOH process yielded higher biodiesel (96.8%) at 60 o C, 90 min, 1.2 % NaOH and 9:1 methanol-oil ratio.
