Pengaruh Penggunaan Katalis Bentonite Clay Pada Pirolisis Sampah Plastik Jenis Low Density Polyethilene (Ldpe) Sebagai Bahan Bakar Alternatif

ABSTRACT
Pyrolysis is the heating of plastic waste at high temperatures, with little or no oxygen, producing products such as oil, gas, and carbon residue. The use of catalysts in the pyrolysis process can accelerate the conversion of plastics, resulting in oil of higher quality. This study aims to investigate the potential of oil from the pyrolysis of Low Density Polyethylene (LDPE) with the addition of bentonite clay as an alternative fuel. The pyrolysis process was conducted experimentally at a temperature of 450 °C with a holding time of 60 minutes, and variations in catalyst composition of 0%, 5%, 10%, 15%, and 20% were tested to determine the optimum conditions. The composition that yielded the highest oil production was then tested at lower temperatures, namely 350 °C and 400 °C, with the same holding time. The most optimal bentonite clay catalyst composition was 15% at 450 °C. Without using a catalyst (0% composition), the oil yield was 54.2%, which increased to 66% with a total feedstock of 500 g; compared to the plastic mass of 425 g, the oil yield reached 82.5%. The oil density ranged around 0.766 g/mL, viscosity at 1.53 cP, calorific value reached 11,302.33 cal/g, and pure hydrocarbons accounted for 94.35%. LDPE pyrolysis oil with bentonite clay as a catalyst exhibited properties closer to diesel and kerosene. Therefore, LDPE pyrolysis oil has the potential to be used as an alternative fuel in energy applications.
