Abstract

The conversion of plastic waste to fuel is a viable approach to address challenges associated with LDPE waste while enhancing energy utilization in pyrolysis. Elevated olefin levels beyond set standards adversely affect exhaust emissions, underscoring the need for hydrogenation. This study comprises multiple phases, including catalyst formulation from natural zeolites, transition metal deposition, and hydrogenation of pyrolytic oil using these catalysts. Results indicate that the Nickel-based catalyst yields a significantly lower olefin yield of 6.1% with Ni/SNZ and 5.76% with NiMo/SNZ, complying with EN228 standards. In contrast, the CoMo/SNZ catalyst significantly increases carbon content to 87.25%, demonstrating improved deoxygenation and achieving the highest HHV of 39.95 MJ/kg, reflecting enhanced liquid product quality for potential alternative fuel applications.
