In response to the escalating global challenge of mounting plastic waste and imperative adopt more sustainable practices for resource utilization, our study focuses on utilization solid (PSW) through a two-stage thermal pyrolysis process. This aims demonstrate its potential as high-performance alternative existing catalytic methods. The experimentation involved processing real scrap PSW material in lab-scale batch set-up, emphasizing optimizing residence time cracking reactor maximize gas yield lower heating value (LHV). underscores advantages employed apparatus comparative analysis with established set-up dedicated maximizing yield. Once operative conditions were explored, resulting products underwent detailed characterization assess their suitability fuel source. also presents practical application produced gaseous fuel, envisioning combustion an internal engine (ICE), known flexibility regarding properties. is demonstrated simulation conducted Unisim Design©. successful experimental showcased optimal achievements (>65 % w/w) LHV (∼41 MJ/kg), comparable that natural gas. emphasizes these alternatives replace fossil fuels, especially context ICE applications. integration plant promising prospects generating electricity transportation sector facilitating power heat reactors.

The benefits of hierarchical zeolites for the conversion bulky molecules like polymeric waste have been reported in literature; however, impact mesopore sizes and connectivities on rates, product selectivities, catalyst deactivation context plastic upcycling has not systematically probed. Here, we synthesized a suite MFI FAU via desilication under varying conditions metal-free polyethylene reactions batch flow (473–523 K). Polyethylene (solid) rates (normalized by Bro̷nsted acid site density) were higher than parent microporous regardless connectivities, i.e., open or constricted, suggesting that incorporation mesopores facilitates diffusion intermediate products to access medium-pore protons successive scission events. Furthermore, branched:linear gaseous ratios produced MFI, since allow egress bulkier without undergoing further secondary events, e.g., isomerization back linear alkanes/alkenes beta scission. Solid with cetyltrimethylammonium bromide (CTABr), FAU, likely because presence CTABr recrystallization leached species form composites (hierarchical ordered mesoporous materials) more isolated mesopores. stagnation despite increased volumes (>0.22 cm3 g–1), highlights importance confinement effects provided micropores cleaving C–C bonds at modest reaction conditions. In situ 1H MAS NMR performed zeolite show PE isomerizes (and potentially deconstructs) temperatures near 450 K, highlighting role sites activating mild Catalyst recyclability studies showed all catalysts undergo during reactions, but extents. Overall, materials better stability materials, although differences between are smaller those MFI. Taken together, these findings demonstrate how from can be controlled fine-tuning identity connectivity
