“…As the most abundant plant biomass resource, lignocellulosic biomass is recognized as the most promising renewable carbon feedstock for liquid fuels and chemicals production. − Biomass-derived furanic compounds, such as furan, furfural, 2-methylfuran, and 5-hydroxymethylfurfural, are important platform molecules that can be obtained from lignocellulose and have attracted significant interest for aromatics production over acidic zeolite catalysts. − In this process, furan undergoes a series of Diels–Alder condensation, decarbonylation, oligomerization, and alkylation reactions to form various olefins and aromatics comprising an active hydrocarbon pool (HCP) within zeolite channels. − The HCP, originally proposed to explain methanol-to-hydrocarbon reactions, describes organics trapped in the zeolite scaffold that reactant molecules interact with, and products are released from a catalytic cycle. − Similar HCP processes have been established for the transformation of methyl halides, methanethiol, biomass pyrolysis, light alkenes, and alkanes , into higher hydrocarbons. A recent study on the co-aromatization of furan and methanol over ZSM-5 zeolite found that furanic compounds can form highly proton-deficient intermediates as HCP species through dehydration or decarbonylation reactions.…”
