摘要：

To increase the activity of the CaO catalyst for biodiesel synthesis, CaO-MgO-Al2O3 was prepared by coprecipitation. CaO, CaO-MgO, and CaO-MgO-Al2O3 were investigated with regard to their dispersibility, hydrophobicity, and thermal stability. The additions of MgO and Al2O3 had a beneficial effect on the activity of the resulting CaO-MgO-Al2O3 catalyst, showing a biodiesel yield of 97.7% because of the improvements in dispersibility and hydrophobicity. CaO-MgO-Al2O3 gave better acid resistance and better reusability, which is important for potential application in biodiesel production.
