Biodiesel Production from Waste Cooking Oil Using Different Heterogeneous Catalysts Support on Alumina

This paper explores the using of waste cooking oil (WCO) as an attractive option to reduce the raw material cost for the biodiesel production. This can be achieved by using two different heterogeneous catalysts Ceria-Magnesium support on Alumina and Ceria-Cobalt support on Alumina. Full characterization have been carried out of the produced catalyst using XRD, SEM and Surface area. The optimum conditions for ceria cobalt are 0.3% catalyst (weight % of oil), and methanol/oil molar ratio 6:1, with temperature 60°C for 1.5 hrs with yield 97% while the same conditions applied for ceria magnesium as methanol/oil molar ratio 6:1, with temperature 60°C for 2 hrs using 0.5% catalyst (weight % of oil), the yield is 90%.
