Highlights
•
Calcination temperature is an important influencing factor in catalytic activity.
•
The optimum calcination conditions were determined to be 850 °C for 2 h.
•
Maximum yield of 79.8% and FAME conversion of 97.1% was achieved.
•
Kinetic data fitted the pseudo-first order model and the Ea was 42.56 kJ mol−1.
•
The novel catalyst can be reused for 3 cycles with a final biodiesel yield of 60%
