| Abstract: | The supported solid base catalyst Na2CO3/Kaolin was prepared by impregnation, and methyl ester biodiesel was prepared from soybean oil and methanol by transesterification with this catalyst. Factors that affected the conversion like reaction time, catalyst dosage, reaction temperature, molar ratio of methanol to oil were investigated, and the optimal reaction condition were analyzed by single-factor experiments. The results showed that under these conditions reaction time 4 h, reaction temperature 60 ℃, catalyst rate 3 %, molar ratio of methanol to oil 12;1, the esterification rate reached 90.5 %. |
