Effect of calcination temperature on the activity of solid Ca/Al composite oxide-based alkaline catalyst for biodiesel production

- A solid base catalyst based on Ca12Al14O33 and CaO was developed.
- The catalyst showed excellent catalytic activity with biodiesel yields >94%.
- The effect of calcination temperature on the catalytic activity was investigated and optimal temperature was determined.
- Structure and properties of the catalyst were studied.
- The synergistic mechanism between crystalline Ca12Al14O33 and CaO of the catalyst was revealed.
