Preliminary study of pellets Refuse Derived Fuel (RDF-5) based on Durian waste for feedstock in fast pyrolysis

The abundance of durian waste in Indonesia encourages the energy potential analysis of waste as a renewable source of energy. Fast pyrolysis had employed to convert the durian waste into gas and bio-oil. Peel and seed of durian (durian waste) was processed into pellets RDF-5 with the natural adhesive material. The RDF-5 in this study was cylindrical with 15 mm diameter and 50 mm length. The analysis of the energy potential of RDF-5 based on durian waste was conducted in different variations of the composition by using bomb calorimeter. Meanwhile, to explore the optimum parameters that affected on the fast pyrolysis process had conducted experiments in different variations of temperature 4000C-6000C. The results showed that the composition ratio between durian waste and natural adhesive material affected to the caloric value of RDF-5. Similarly, the quality and quantity of bio-oil and gas were affected by the temperature. When the temperature increases, the quality and quantity of bio-oil and gas also increases. This paper will be discussed the pyrolysis parameters on the fast pyrolysis process of RDF-5 based on durian waste in detail. (paper)
