Catalytic fast pyrolysis (CFP) of bagasse and bio-plastic (chicken feather keratin) and their mixtures were conducted to produce aromatic hydrocarbons over a HZSM-5, USY, and dual-catalysts layout. The effects of temperature, co-feeding ratios, feed-to-catalyst ratios and dual catalysts on hydrocarbon yields and selectivities were investigated. The results show a general improvement in the aromatic hydrocarbons yields in all cases compared to non-catalytic and pure biomass pyrolysis. The aromatic hydrocarbons increased by 10 fold with the increase of temperature from 400 °C to 700 °C. The aromatic yields increased 1.5 times at co-feeding, 2.0 greater at feed/HZSM-5 ratio of 1:6, 1.2 times at feed/USY ratio of 1:16, and 2.66 times at USY/HZSM-5 scenario. The selectivities towards benzene increased, at higher co-feeding ratios, while that of toluene shows an opposite trend. Xylenes selectivities were less sensitive to the changes of co-feeding ratios. In contrast, the USY catalyst only produced little amount of toluene and xylenes. The dual catalyst design (USY/HZSM-5) resulted in the highest aromatic yields, than other catalyst design scenarios. The pyrolysis temperature is a significant parameter for hydrocarbon production. Co-feeding bagasse and bio-plastic enhanced biomass conversion to aromatic compounds. For any type of zeolite catalyst, there was an optimum feed-to-catalyst ratio that generated maximum hydrocarbons. Dual catalyst layout shows a new opportunity for efficient conversion of biomass materials into hydrocarbons. [ABSTRACT FROM AUTHOR]
