Palm biodiesel production using by heterogeneous catalyst based corn cobs

In this research, heterogeneous solid base catalysts were derived from corn cobs. the solid base catalyst was obtained which was then used for the production of palm oil biodiesel with a transesterification reaction. The catalyst prepared corn cobs with impregnation of NaOH then calcined temperature 400°C at 2 hours. The optimum conditions for the function of duration reaction time and catalyst amount obtained catalyst amount 3% at 60 minutes, temperature 65°C, ratio methanol to oil 12:1 obtained yield of biodiesel 93.10% while the function of reaction temperature and catalyst amount obtained catalyst amount 2.5%, ratio methanol to oil 12:1, at duration time is 60 minutes and temperature 60°C obtained yields 97.35%. The catalyst was easily separated from the reaction mixture by filtration and able to reuse for 2 times. The biodiesel product is specified with EN14214. Heterogeneous catalysts derived from corn cobs that show high-cost potential and produce easy ones as solid catalysts for the transesterification reaction of biodiesel production.
