Fe‐modified ZSM‐5 (Fe/ZMS‐5) catalysts were prepared and used during catalytic fast pyrolysis of biomass (CFP) to achieve high yields of monocyclic aromatic hydrocarbons (MAHs) and inhibit the formation of polycyclic aromatic hydrocarbons (PAHs). The catalytic effects on the yield and selectivity of aromatic hydrocarbons (aromatics) under various reaction conditions were evaluated. Under the optimal reaction conditions at 600°C and mass ratio of catalyst to biomass (catalyst/biomass) of 10/1, the 15 wt% Fe/ZMS‐5 catalyst displayed the highest productions of MAHs and PAHs with the values of 212.2 mg and 94.5 mg per gram biomass, corresponding to the MAHs selectivity of 69.2%, which were significantly higher than those obtained over ZSM‐5 alone. The origins of aromatic hydrocarbons were explored by CFP of three typical components of biomass. Combined the characterization and reaction performance of catalysts, the catalytic mechanisms of Fe/ZSM‐5 catalyst for biomass pyrolysis to produce aromatic hydrocarbons were put forward.

通过铁改性的ZSM-5催化剂快速生物质热解提高单环芳烃生产

制备了铁改性的ZSM-5（Fe / ZMS-5）催化剂，并将其用于生物质的快速催化热解（CFP）中，以实现单环芳烃（MAH）的高收率并抑制多环芳烃（PAH）的形成。评价了在各种反应条件下对芳烃（芳烃）的产率和选择性的催化作用。在600°C的最佳反应条件下，催化剂与生物质的质量比（催化剂/生物质）为10/1时，Fe / ZMS-5含量为15 wt％的催化剂显示出最高的MAH和PAH生成量，值为212.2 mg每克生物质94.5 mg，对应的MAHs选择性为69.2％，明显高于仅通过ZSM-5获得的MAHs选择性。通过CFP探索了生物质的三种典型组分的芳烃来源。
