Waste Peel of Durian as Solid Cataysts for Biodiesel Production

Abstract

Abstract In this study, peel durian ash was used as a solid catalyst to convert rubber seed oil into biodiesel production via transesterification reaction. The catalyst was fabricated by simple burning and calcined at 600°C for 8 h. The morphology of particles was confirmed by Scanning Electron Microscopy (SEM). The Energy-dispersive X-ray Analysis (EDX) was used to obtain the atomic composition and percentage of the catalyst. The reaction was carried out at 65°C for 1 h. Whereas, the catalyst loading were varied of 1.0%, 2.5%, 5.0%, 10% and 15% wt.%. From EDX data was confirmed that the ash catalyst composes of the potassium oxide (K2O) as the dominant compound. The performance of the catalyst was evaluated from a transesterification reaction for biodiesel production. The highest biodiesel yield of 96.5% was obtained in the reaction using a catalyst of 10 wt.%. The density obtained was 0.865 gr/cm3 confirming the produced biodiesel complies with the SNI standard.
