Abstract

Biodiesel has been introduced as an alternative fuel to replace the depletion of diesel oil and environmental pollution. Thus, the production of biodiesel is in demand and usually, conducted through base catalysed transesterification reaction towards the low grade cooking oil. In this research, bimetallic oxide cerium-calcium catalyst supported on activated carbon (AC) was prepared using impregnation method. Optimum catalytic parameter was observed with 30 wt.% of cerium loading on Ce/Ca/AC catalyst calcined at 500 °C and gave the highest free acid methyl ester (FAME) yield of 73.5% with fixed reaction conditions (65 °C, 1:18 wt.% oil to methanol ratio, 6 wt.% catalyst loading and 3 hours of reaction time). The enhanced activity of Ce/Ca/AC catalyst can be ascribed to the uniform needle-like morphology and well dispersion of the Ce-Ca on the support surface as indicated by FESEM images. XRD showed that the Ce/Ca/AC catalyst was in amorphous phase with BET surface area of 149.18 m2/g. These results showed Ce/Ca/AC catalyst has promising potential to be used for production of FAME from low grade cooking oil.
