Abstract • Catalytic treating of biomass fast pyrolysis vapors offers a promising route to convert many different types of lignocellulosic biomass into biofuels. Considerable research efforts have focused on using zeolite catalysts, especially the microporous HZSM-5 zeolite. Unfortunately, the zeolite’s initial high activity in forming coke and light gases reduces the overall oil yield. In this contribution, we synthesized conventional HZSM-5 zeolite, mesoporous HZSM-5 zeolite, and a core-shell catalyst consisting of mesoporous HZSM-5 zeolite coated with a thin layer (

介孔 HZSM-5 和 Silicalite-1 包覆的介孔 HZSM-5 催化剂用于秸秆快速热解蒸气脱氧的性能

摘要 • 生物质快速热解蒸汽的催化处理为将许多不同类型的木质纤维素生物质转化为生物燃料提供了一条有前景的途径。大量的研究工作集中在使用沸石催化剂上，尤其是微孔 HZSM-5 沸石。不幸的是，沸石在形成焦炭和轻质气体方面的初始高活性降低了总油产量。在这一贡献中，我们合成了传统的 HZSM-5 沸石、介孔 HZSM-5 沸石和由薄层涂覆的介孔 HZSM-5 沸石组成的核壳催化剂（
