Hydrotalcite was prepared by co-precipitation of magnesium and aluminum nitrate solution. After calcination, the hydrotalcite was converted to Mg-Al composite oxides. The transesterification of rapeseed oil was carried out by using treated Mg-Al composite oxides as catalyst. Through orthogonal analysis, the optimum reaction conditions obtained for the transesterification were set at temperature 65 °C , mole ratio of methanol to rapeseed oil 6 ! 1, reaction time 3 h, and catalyst dosage 2% (on rapeseed oil mass). The yield of fatty acid methyl ester (biodiesel fuel) was 95. 7%. The fluidity of the biodiesel fuel at low temperature was much better than that of No. 0 diesel fuel and the flash point was as high as 170 °C with a sound oxidation stability. Other principal physicochemical properties of the biodiesl fuel were similar to that of No. 0 diesel fuel. The biodiesel fuel could be blended with No. 0 diesel fuel at any ratio. |
