Abstract

Nowadays, the biodiesel is a biofuel that has been encouraged to increase the production due to it can use to replacethe diesel fuel. However, as the high price of raw materials and catalysts, this research was using the chicken fat as the rawmaterial and CaO from calcined chicken bones as a heterogeneous catalyst. In addition, these materials will be contributed toreduce the cost of the production and eliminate wastes. For the best results, it was compared with the homogeneous catalystwhich was NaOH and reacted with the transesterification of chicken oil. Furthermore, the results showed that the optimumconditions in the reaction is the methanol: oil molar ratio of 12:1, 4 %wt CaO, the reaction temperature of 60oC for 2 hrs whichyield 61 % methyl ester when compared with NaOH yield 93 % methyl ester. Therefore, when compared with the NaOH, it wasproduced 93 % yield of methyl ester because of NaOH was high alkaline leading to the better result in a catalyst. On the otherhand, the reusable for the production of biodiesel was the advantage of the heterogeneous catalyst.
