Transesterification of Pangium Edule Reinw oil to biodiesel using durian rind ash as heterogeneous catalysts

The purpose of this research is to know the effect of addition durian rind ash as a catalyst for biodiesel production. Waste of Durian rind ash containing potassium oxide compound can be used as a novel heterogeneous catalyst for the transesterification process. Potassium oxide in durian rind ash catalyst has been synthesized by the simple burning method. In this research, durian rind ash catalyst was potentially for biodiesel production from Pangi (Pangium Edule Reinw) oil. The optimum biodiesel yield of 96.24% can be achieved over durian rind ash catalyst of 5 wt.% of catalyst, reaction temperature 65°C at 1 hour, and a methanol-to-Pangi oil ratio of 8:1. The characterization was also conducted using X-ray diffraction (XRD) and Scanning electron microscopy (SEM).
