| Summary: | Biodiesel is becoming more important as it is chosen to be one of the alternative fuels to replace fossil fuel nowadays, as well as waste materials also play a significant role in cheaper and greener fuels. In this research, waste fish bones modified with potassium hydroxide (KOH) were utilized as a cost-effective catalyst in the
transesterification of RBD palm oil with methanol. The waste fish bones were calcined at 900 ℃ for 2 h and then added with different concentration of KOH to form K+ impregnated calcined fish bones (K-CFB). The prepared catalysts were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy-energy dispersive X-ray (FESEM) and thermogravimetric analysis (TGA). The characterization results showed that K+ was successfully impregnated on calcined fish bones (CFB). Methyl ester was yielded at the highest content of 96.14 wt. % when the conditions are optimized at 5 wt. % catalyst loading, methanol to oil ratio of 12:1 and reaction time of 3 h. The CFB loaded with 10 wt. % KOH (10K-CFB) was found to be a potential heterogeneous base catalyst for transesterification due to its high catalytic activity. |
