H-ZSM5 Catalyzed Co-Pyrolysis of Biomass and Plastics

Abstract: This study aims to address two important problems vital to agriculture: disposal of agricultural plastics and production of drop-in fuels from biomass via co-pyrolysis of both feedstocks. Mixtures of biomass (switchgrass, cellulose, xylan, and lignin) and plastic (polyethylene terephthalate (PET), polypropylene (PP), high density polyethylene (HDPE), low density polyethylene (LDPE), and polystyrene (PS)) were subjected to catalytic fast pyrolysis (CFP) at 650 °C in the presence of H-ZSM5. A micro-pyrolyzer cou… Show more

“…In addition, it is proved that the endothermic pyrolysis event accompanied by the depolymerisation of polymeric chains and the formation of volatile low molecular products was detected for chitin. Catalysts play a fundamental role in the pyrolysis process to steer the selectivity of targeted compounds and promote the quality of pyrolysis oil (Ben & Ragauskas, 2013;Dorado et al, 2014;Xu et al, 2015). In this study, the catalytic pyrolysis of chitin biomass was examined with GlcNH 2 as the model substrate and the mesoporous molecular sieves, SBA-15 and MCM-22, as the catalysts.…”

“…It is commonly accepted that the acidic catalysts, such as, H 2 SO 4 , ZnCl 2 and zeolite (H-Y, H-ZSM5 and ZSM-5), show the decarboxylation ability from the biomass. This additional de-oxygenation reaction brought by the catalysts is responsible for the low char collection (Ben & Ragauskas, 2013;Carlson, Jae, Lin, Tompsett, & Huber, 2010;Dorado et al, 2014;Taarning et al, 2011).…”

“…Co-pyrolysis of polymers with biomass resulted in upgraded bio-oil by reducing the acidity, density, and oxygen content (Bhattacharya et al, 2009;Martínez et al, 2014). Catalytic copyrolysis of polymers with biomass also significantly improved the quality of bio-oils (Dorado et al, 2014). Studies on char produced from co-pyrolysis of biomass and polymers were also conducted.…”

“…In the commercial plants, the mineral-based catalysts such as Al 2 O 3 and zeolites have attracted more attentions for the waste oils upgrading [25][26][27]. For example, ZSM-5 is considered to be a promising zeolite-based catalyst for pyrolysis vapor upgrading to produce considerable petrochemicals (e.g., aromatics and olefins) [28][29][30][31]. In our previous work, the zeolite catalysts (e.g., natural zeolite, ZSM-5) were used for the fuel oil production from two-stage pyrolysis-catalytic reforming of brominated high impact polystyrene [32,33].…”
