Abstract
ZnO nanorods synthesized via a wet chemistry approach were used as catalysts for the production of biodiesel via methanolysis of olive oil. Conversions of the oil to biodiesel as high as ~95 % were observed at 150 °C. A kinetic study was conducted to evaluate the reaction rate parameters. Interestingly, at short reaction times, the overall rate was dominated by mass transfer limitations. Then, reaction kinetics dominated at moderate to longer times. In the reaction kinetics regime, a pseudo-first order reaction rate constant with respect to the oil of ~0.51 h−1 was observed.
