Insight of Elementary Steps on the Polyethylene and Polypropylene Co‐Pyrolysis

Carbon and Hydrogen, EarlyView.
Pyrolysis of PP initiates first, accelerating PE cracking via secondary radical transfer, leading to n‐hydrocarbon yield enhancement. Py–GC/MS and nanoreactor computation are in agreement on the elementary step proposal. ABSTRACT Pyrolysis with gas chromatography & mass spectrometry (Py–GC/MS) technique was employed to analyze the yield variation of ...

Upcycling Real‐World Post‐Consumer Polyolefins Plastics Into Light Olefins Via Microwave‐Assisted Processing

Carbon Energy, EarlyView.
Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular
