| Abstract: | A solid base nanocatalyst Zr-0. 5-550 was prepared by ZrO2 loaded with Na2CO3. The optimal conditions for the catalyst preparation were investigated： nzr/nNa of 0. 5 and calcining temperature of 550 ℃. The transesterification of soybean oil and methanol to biodiesel catalyzed by Zr-0. 5-550 was studied. The results showed that the optimal reaction conditions were as following. molar ratio of methanol to oil 12 ： 1, mass ratio of catalyst to soybean oil 5.0%, reaction time 4. 0 h and reaction temperature 60 ℃. The yield of biodiesel reached 97. 9% under the optimal reaction conditions. The catalyst for transesterification of biodiesel has higher catalytic activity and good reusability. |
