The invention discloses a preparation method of an active component non-uniform distribution spherical catalyst for producing aromatic hydrocarbon from methanol, and belongs to the technical field ofmethanol deep processing. According to the reparation method, a method of one-step impregnation method combined with multi-step post-treatment is used to realize control of a distribution situation ofmetal active components on the catalyst, and finally the "yolk type" spherical catalyst is obtained. The catalyst prepared by the method has higher activity, higher aromatic selectivity, and lower CO selectivity in the reaction of producing aromatic hydrocarbon from methanol.
