| 英文摘要 | PurposeThis work aims to investigate the thermal behavior and kinetic characteristics of polyethylene (PE) pyrolysis over Cu/Ce modified ZSM-5. The influences of metal types, particles size of active center and interaction of Cu-Ce species on products distribution are elucidated.MethodsMetal-modified ZSM-5 catalysts were prepared by negative pressure impregnation method. Catalytic fast pyrolysis and thermogravimetric experiments were conducted using Py-GC/MS and TG/MS for the qualitative and quantitative analysis of pyrolysis products.ResultsMorphology characterization indicated the interaction of Cu-Ce species facilitated the regulation of active center size into a nanoparticle scale. The final products were restricted to a carbon number of less than 9 over CuCe/ZSM-5. Cu-Ce modification increased the aliphatic content from 58.5 to 76.1%. Kinetic analysis revealed a remarkable reduction in activation energies during both the intermediate and final stages, where an average decrease of 30% was achieved.ConclusionThe synergistic effects of Cu0 and CeOx facilitated the formation of more short chain olefins by enhancing C-C bonds cleavage activity. Undesired polycyclic aromatic hydrocarbons (PAHs) were avoided by the optimal steric hindrance of CuCe/ZSM-5. |
