Evidence Details
When the catalyst was used for one, two, three, and four cycles, the yield of FAME was 90.05%, 89.95%, and 87.75% to 85.25%.
The experimental results showed that a 2.0:1 volume ratio of methanol to oil, 65 °C reaction temperature, 30 min reaction time and 10 wt.% catalyst amount gave the highest the yield of biodiesel.
Additional source evidence: source values include 2.0:1, 65°C, 30 min, 94.75%.
The yield of biodiesel achieved by the conventional water-bath was only 42.33%. On the contrary, the yield of biodiesel obtained by microwave irradiation was significantly higher, being 94.75%.
The flask was rested on the Xianghu microwave reactor XH-100A (Beijing Xianghu Science and Technology Development Co., Ltd) which controlled the whole reaction conditions including reaction temperature, stirring speed and reaction time.
The catalyst has the highest total basicity amount (B = 3.980) when the mole ratio of Na/Zr of the catalyst is 2.0 at the same calcination temperature and the best yield of biodiesel (92.06%) was obtained.
Additional source evidence: source values include 2.0:1, 600°C.
Composition evidence: source values include 1%, 5%.
27.45% → 92.06%
300°C：60.44%
400°C：69.11%
500°C：92.06%
600°C：93.51%
700°C：77.89%
Mechanism / Method Highlights
- Effective solid-base sites formed on the doped zirconia surface are the core catalytic basis for efficient methanol-oil transesterification.
- Microwave irradiation directly provides faster and more uniform heating, improving transesterification efficiency while the doped zirconia catalyst supplies the active basic sites.
