The use of H-ZSM-5 with various binders (Al₂O₃, SiO₂, and kaolinite, 10 wt% on catalyst formulation) for the catalytic conversion of glycerol to bio-based aromatics (GTA) was investigated in a continuous bench-scale unit at a pyrolysis temperature of 450 °C, catalytic upgrading temperature of 500 °C, WHSV of pure glycerol of 1 h⁻¹, and atmospheric pressure, and their performance was compared to H-ZSM-5 (SiO₂/Al₂O₃ molar ratio of 28). The latter gave a peak BTX carbon yield of ca. 31.1C.%, a life-time of ca. 220 min, and a total BTX productivity of ca. 312 mg BTX g⁻¹H-ZSM-5. The introduction of binders affects catalyst performance, which is the most profound and promising for the H-ZSM-5/Al₂O₃ catalyst. It shows a prolonged catalyst life-time of ca. 320 min and a higher total BTX productivity of ca. 518 mg BTX g⁻¹H-ZSM-5, compared to the H-ZSM-5 without a binder. Catalyst characterization studies show that the addition of the binder does not have a major effect on the specific surface area, total pore volume, and total acidity. Other relevant properties were affected, though, such as micropore volume (SiO₂), a reduced Brønsted acidity (Al₂O₃, and SiO₂), and reduced crystallinity (SiO₂). Coke formation causes severe catalyst deactivation, ultimately leading to an inactive catalyst for BTX formation. Catalyst characterization studies after an oxidative regeneration showed that the textural properties of the regenerated catalysts were close to those of the original catalysts. However, some dealumination of H-ZSM-5 occurs, resulting in decreased crystallinity and acidity, causing irreversible deactivation, which needs attention in future catalyst development studies.

在连续工作台上研究了 H-ZSM-5 与各种粘合剂（Al ₂ O ₃、SiO ₂和高岭石，占催化剂配方重量的 10%）用于将甘油催化转化为生物基芳烃 (GTA) 的用途热解温度为 450 °C、催化升级温度为 500 °C、纯甘油的 WHSV 为 1 h ^-1和大气压下的规模单元，并将其性能与 H-ZSM-5 (SiO ₂ /Al ₂ O ₃摩尔比为28)。后者给出了大约的峰值 BTX 碳产率。31.1C.%，使用寿命约。220 分钟，总 BTX 生产力约为。312 毫克 BTX 克^-1H-ZSM-5。粘合剂的引入影响了催化剂的性能，这对H-ZSM-5/Al ₂ O ₃催化剂来说是最深刻和最有前途的。它显示出延长的催化剂寿命约。320 分钟和更高的总 BTX 生产力约。与不含粘合剂的 H-ZSM-5 相比，518 mg BTX g ^-1 H-ZSM-5。催化剂表征研究表明，粘合剂的添加对比表面积、总孔体积和总酸度没有主要影响。但是，其他相关特性也受到影响，例如微孔体积 (SiO ₂ )、布朗斯台德酸度降低（Al ₂ O ₃和 SiO ₂）和结晶度降低（SiO ₂）。焦炭的形成会导致催化剂严重失活，最终导致 BTX 形成的催化剂失活。氧化再生后的催化剂表征研究表明，再生催化剂的结构特性接近原始催化剂的结构特性。然而，H-ZSM-5 会发生一定程度的脱铝，导致结晶度和酸度降低，导致不可逆的失活，这在未来的催化剂开发研究中需要注意。
