Indonesia Natural Zeolite as Heterogeneous Catalyst for Biodiesel Production

Abstract

The problem associated with biodiesel production is economic feasibility. The biodiesel cost will reduce when the low cost feedstock was used. Kapok seed oil (KSO) is a promising candidate as raw material for biodiesel synthesis. In this research, the investigation of biodiesel synthesis from KSO was studied using Indonesia Natural Zeolite as heterogeneous catalysts. The catalyst was tested to synthesize biodiesel from KSO. The reaction temperatures, KSO to methanol mole ratio, and catalyst amount were varied to examine their effects on biodiesel synthesis. The highest biodiesel yield of 84% were obtained at 65°C of reaction temperature, 1:16 of KSO to methanol mole ratio, and 10% of catalyst amount.
