initially). These changes brought the product within industrial feedstock specifications. These improvements translated into enhanced cracking performance. The hydrotreated pyrolysis diesel blend achieved ethylene yields of up to 32 wt% at 880 °C, surpassing fossil naphtha while suppressing CO and aromatic by-products such as benzene, toluene, and xylenes (BTX). The results establish hydrotreatment as a critical enabler for converting waste-derived pyrolysis oils into cracker-ready feedstocks, supporting their integration into petrochemical infrastructure and advancing a circular economy for plastics.
