摘要

研究了以具有分级孔系统的沸石为原料制备的4.0% Mo/ZSM-5催化剂的理化性能和催化性能。研究了附加介孔结构沸石的合成条件对其结构和酸性特性的影响。采用x射线衍射分析和高分辨率扫描透射电子显微镜对合成的沸石及其催化剂的晶体结构和形貌进行了表征。结果表明，介孔分子筛制备的4.0% Mo/ZSM-5催化剂在甲烷脱氢芳构化过程中表现出较高的活性和稳定性。

Study of Methane Aromatization over Mo-Containing Zeolite Catalysts with a Hierarchical Pore System

Physicochemical and catalytic properties of 4.0% Mo/ZSM-5 catalysts manufactured on the basis of zeolites with a hierarchical pore system are investigated. The effect of the conditions of synthesis of zeolites with an additional mesoporous structure on their textural and acidic characteristics is studied. The structure and morphology of crystals of synthesized zeolites and catalysts produced from them are determined by the methods of X-ray diffraction analysis and high-resolution scanning transmission electron microscopy. It is shown that 4.0% Mo/ZSM-5 catalysts produced from zeolites with a mesoporous structure exhibit higher activity and stability in the course of methane dehydroaromatization.
