【Abstract】 Focusing on three key conversion pathways of waste polyolefin plastics including production of olefins, aromatics, and oxygen-containing compounds, the latest advances on chemical upcycling technologies were reviewed from the perspectives of catalyst structure design, reaction pathway regulation, energy input modes, and product distribution patterns, and future development trends were proposed. It was pointed out that, with the continuous integration of catalytic material design, novel energy-driven technologies, multiscale computational simulation, and scale-up studies in reaction engineering, a more efficient, controllable, and greener system for the high-value recycling and reusing for waste polyolefin plastics would be achieved in the future.更多还原
