FIELD: zeolite catalysts. SUBSTANCE: spherical granules are formed basing on zeolite ZSM and aluminum hydroxide after preliminarily treatment of zeolite with alcoholic solution of salt containing 0.5 to 5.0 wt % gallium or zinc at zeolite- to-solution weight ratio (0.5-3.0):1 and drying. Treated zeolite is extruded with binder and aluminum hydroxide, after and wet extruded material is processed on disk granulator, after which dried and calcined in air flow at 110-150 C. EFFECT: increased mechanical strength of catalyst granules and essentially raised (to 80-90%) content of zeolite using simplified technology. 2 cl, 2 tbl, 9 ex
