To increase the activity of the CaO catalyst for biodiesel synthesis, CaO–MgO–Al 2 O 3 was prepared by coprecipitation. CaO, CaO–MgO, and CaO–MgO–Al 2 O 3 were investigated with regard to their dispersibility, hydrophobicity, and thermal stability. The additions of MgO and Al 2 O 3 had a beneficial effect on the activity of the resulting CaO–MgO–Al 2 O 3 catalyst, showing a biodiesel yield of 97.7 % because of the improvements in dispersibility and hydrophobicity. CaO–MgO–Al 2 O 3 gave better acid resistance and better reusability, which is important for potential application in biodiesel production.
