Uittreksel

Aromatization of furan and substituted furans over zeolite catalysts is a promising reaction to convert cellulose-derived compounds into valuable aromatic hydrocarbons and light olefins. A lack of understanding of the reaction mechanism however hinders further development of this process. Here, we present a novel view on the reaction mechanism, underlying the chemistry of furan and methanol co-aromatization over HZSM-5 zeolite catalyst. Applying 13C isotope labelling in a combination with NMR spectroscopy and high temporal resolution GC-MS analysis, we reveal that aromatization of furan and methanol are not mechanistically separated and can be described within the Dual-Cycle hydrocarbon pool mechanism. Co-feeding furan with methanol leads to a significant enhancement of light aromatics selectivity and increased catalyst life-time.
