Method for improving catalytic property of methane aromatization catalyst

The invention relates to a method for improving the catalytic property of methane aromatization catalyst, belonging to the technical field of molecular sieve catalysis. The invention is characterized in that on the condition of no-second template, the crystal growth of zeolite molecular sieve is controlled by reasonablely controlling zeolite molecular sieve synthesis conditions such as synthesis formulation, charging sequence, ageing time, crystallization temperature, crystallization time and the like, small molecular sieve crystal is used for assembly and intergrowth to form MCM-22 and ZSM-5 molecular sieve assembly with multi-stage pore path structure, Mo or Re used can be adopted as active component to perform loading and modification to the prepared molecular sieve assembly, and the invention provides Mo-based MCM-22 and ZSM-5 molecular sieve assembly catalysts and an application thereof in methane non-oxidative aromatization reaction. The effects and the benefits of the invention is that the operation is simple, the cost is low and in methane non-oxidative aromatization reaction, the multi level structure assembly catalyst prepared by the method of the invention has better catalytic performance compared with the traditional catalyst.
