Abstract
En 中文
• Green aromatics can be produced from biomass pyrolysis oil model compounds. • Zn/ZSM-5 catalysts synthesized by ion-exchange outperform impregnated ones. • A balanced Brønsted/Lewis (B/L) acidity ratio is key for tuning BTX selectivity. • High B/L ratios promote xylenes, while lower ratios favor toluene formation. • A total BTX yield of 65% was achieved at 500 °C using ion-exchanged Zn-80 catalyst.
