Isomorphous Substitution of Gallium into MFI-Framework Zeolite Increases 2,5-Dimethylfuran to Aromatics Selectivity and Suppresses Catalyst Deactivation

Abstract The valorization of biomass-derived molecules into commodity chemicals is important for the transition to renewable feedstocks. model platform molecule 2,5-dimethylfuran (2,5-dmf) can be converted value-added aromatics such as benzene, toluene, and xylenes (BTX) over zeolite catalysts. To explore role acid site(s) in BTX selectivity, gallium has been isomorphously substituted framework, resulting a Ga-silicate. Compared ZSM-5 counterpart, this modification shows enhanced benzene selectivity well resistance deactivation by coke continuous catalytic performance tests.
