Production of biodiesel fuel by transesterification of different vegetable oils with methanol using Al2O3 modified MgZnO catalyst

► Versatile heterogeneous MgZnAlO catalyst used for synthesis of FAME. ► Catalyst shows high activity on different types of vegetable oils. ► Preparation procedure and treatment conditions resulted in stable composite oxide. ► Optimum conditions of FAME synthesis were determined for the oils. ► The catalyst has good recoverability and able to use in five successive cycles with stable conversions.
