摘要: Abstract Biomass-derived materials offer a huge potential as an alternative templating agent for tailoring new pore systems in zeolite to enhance its catalyst properties. Hierarchical ZSM-5 (H-type) was prepared this study with the assistance of alkaline lignin re-assembly alkali-treated parent material. The catalytic performance novel tested co-pyrolysis softwood biomass and LDPE mixture, product distribution optimized varying reaction temperature (˚C) plastic loading (g/g biomass). Results suggested that enlarged openings hierarchical facilitated abundant reactive species, including macromolecule oxygenates derived from fraction softwood, deoxygenated products pass through layer. higher selectivity desirable aromatic hydrocarbons well coke formation inhibition were obtained at 450 ˚C compared zeolite. Thus, synergy blending intensified acid-catalyzed cracking aromatization during upgrading.
