Burn, baby, burn! A new bifunctional catalyst (Ga/ZSM-5) displays increased selectivity for the production of aromatic compounds during the catalytic fast pyrolysis of biomass. With this Ga-promoted ZSM-5 catalyst, olefins such as ethylene and propylene, which are produced as intermediates, are more efficiently converted into aromatic compounds, especially benzene. Ga/ZSM-5 also promotes decarbonylation and olefin-aromatization reactions.
