The main aim of this study was to investigate the catalytic properties of Al2O3-supported Sn02 for the conversion of waste vegetable oil into biodiesel. The effect of support pore size on waste oil conversion was investigated at 100 and 200 °C by using a-Alumina (with larger pore size) and γ-Alumina (with smaller pore size) respectively as support for Sn02. The effect of pore-size on conversion was found to depend on the operating temperature. At low temperature, i.e. 100 °C, higher conversion for waste vegetable oil was measured on Sn02 catalyst supported on α-Al2O3 than the catalyst supported by γ-Al2O3. This effect became less significant at 200 °C. It was also observed that the oil conversion increased with an increase in reaction temperature and reaction time.
