To enhance the catalytic performance in coaromatization of hexane and methanol, a hierarchical catalyst, M/AT-HZ ([Zn,5Cr,3P]/AT-HZSM-5) was prepared using alkali treatment. The morphological, textural, and acidic properties were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), N₂ adsorption/desorption and Fourier transform infrared spectroscopy of pyridine adsorption (py-FTIR). The better catalytic performance and longer lifetime in the coaromatization of hexane and methanol, compared to that of the hierarchical M/HZ were ascribed to the formation of mesopores. The hierarchical M/AT-HZ-30 exhibited a longer lifetime of over 160 h, which was three times that of M/HZ. The reasons for the deactivation are discussed in detail.

为了提高己烷和甲醇共芳构化的催化性能，使用碱处理制备了分级催化剂 M/AT-HZ ([Zn,5Cr,3P]/AT-HZSM-5)。通过 X 射线衍射 (XRD)、透射电子显微镜 (TEM)、N ₂吸附/解吸和吡啶吸附的傅里叶变换红外光谱 (py-FTIR)表征了形态、结构和酸性特性。与分级 M/HZ 相比，己烷和甲醇的共芳构化具有更好的催化性能和更长的寿命，这归因于中孔的形成。分层 M/AT-HZ-30 的寿命更长，超过 160 小时，是 M/HZ 的三倍。详细讨论了停用的原因。
