| Abstract
| - The transesterification of rapeseed oil with methanol was carried out using a novel KF-loaded Eu2O3 catalyst. It was found that the catalyst with 15 wt % loaded KF and calcined at 873 K showed the optimum activity. X-ray diffraction (XRD), Fourier transform infrared (FTIR), CO2-temperature-programmed desorption (TPD), and the Hammett titration method were employed for the catalyst characterization. The results showed that the activity of the catalysts was related with their basicity. The influence of various reaction variables on the conversion was also discussed. The mechanism for the formation of basic sites and the phase change of the KF-loaded Eu2O3 catalyst with different calcination temperatures is proposed.
