Modelling of the Homogeneous Transesterification of Jatropha Curcas Seed Oil
Authors: Akhihiero ET, Odisu T
Transesterification of Jatropha seed oil with methanol using sodium hydroxide as a catalyst was carried out in an improvised batch reactor. Molar ratio of methanol to oil of 8:1 was used for the reaction. From the start of the reaction, aliquots of the reaction mixture were withdrawn at every 15 minutes interval of time for Gas Chromatographic analysis to determine percentage fatty acid methyl ester formed. Kinetic equations were used to model the system in the LabView software environment. The rate constants were computed by directly evaluating the system of first-order differential equations using mole concentration values obtained during the experiment. The rate constants (k1, k2 and k4) at 60 oC were found to be 3.12, 2.03 and 0.06 L mol-1min-1 respectively.
