This study presents a novel method for recycling polyolefin plastic waste into light olefins (C2-C4) using Rapid Pulse Joule Heating (RPH) over an H-ZSM-5 catalyst. The process enables efficient deconstruction of polyolefin waste into light olefins in milliseconds with high productivity and selectivity, achieving over 90% product fraction towards C2-C4 hydrocarbons. The RPH approach offers significant advantages over traditional methods, including higher polymer-to-catalyst ratios, reduced catalyst deactivation, and enhanced selectivity. The study demonstrates that pulsed operation and steam co-feeding improve the efficiency of the process, minimizing coking and enhancing product yield. The catalyst is essential in producing a narrow distribution of light olefins, and the process is resilient to additives and impurities in real-world plastic waste. The RPH method is compared to Continuous Joule Heating (CJH), showing that RPH achieves higher product fractions and better catalyst reusability. Co-feeding steam further enhances the process by reducing coking and increasing monomer production. The study also evaluates the performance of the RPH method with various feedstocks, including real-world plastics, demonstrating its versatility and effectiveness in converting polyolefin waste into valuable monomers. The RPH approach offers a promising solution for the circular management of polyolefin plastic waste, with potential for sustainable and energy-efficient recycling. The method is a laboratory-scale framework with potential for further development and commercialization.This study presents a novel method for recycling polyolefin plastic waste into light olefins (C2-C4) using Rapid Pulse Joule Heating (RPH) over an H-ZSM-5 catalyst.
