Pemanfaatan Abu Tulang Ayam sebagai Katalis Heterogen (CaO) dalam Proses Pembuatan Biodiesel dengan Menggunakan Pelarut Etanol

Abstract

Biodiesel is one of the most potential of alternative energy as a renewable and environmentally friendly. Processing biodiesel is generally made by transesterification using heterogeneous base catalyst. Chicken bone ash (CaO) is a heterogeneous base catalyst non-corrosive and environmentally friendly, can be easily separated from the product by filtration and disposal issues fewer than homogeneous catalysts. This catalyst was isolated from chicken bones made by milling chicken bones and do calcination process. Some other important variables other than the selection of the catalyst is the catalyst dosage, molar ratio and the reaction temperature. The highest yield of biodiesel produced was 90.052 % with the molar ratio is 17: 1, reaction temperature is 70 ° C and 7% catalyst (w / w) with reaction time of 7 hours and stirring speed of 500 rpm as a constant variable.
