FIELD: chemistry. ^ SUBSTANCE: invention relates to petrochemical and chemical industry, particularly a method of preparing moulded catalysts for conversion of methane into aromatic hydrocarbons and hydrogen in nonoxidative conditions. The invention describes a catalyst for a nonoxidative methane conversion process, containing high-silica zeolite H-ZSM-5, a binding additive - calcium form of montmorillonite, modifying elements - molybdenum and cobalt, where content of the binding additive in the catalyst is not more than 40.0 wt %, while content of molybdenum and cobalt is not more than 3.0 wt % and 1.0 wt %, respectively. Described is a method of preparing a catalyst, involving modification of zeolite with promoting elements through successive wetness impregnation of zeolite H-ZSM-5 with molybdenum and cobalt salt solutions, followed by calcination, and then mixing the zeolite modified with metals with a binding additive suspension in a given proportion to obtain a moulding mass and moulding said mass into granules in a moulding device. The invention also describes a method for nonoxidative conversion of methane in the presence of the catalyst described above. ^ EFFECT: high efficiency of the nonoxidative methane conversion process owing to high activity and stability of the catalyst. ^ 4 cl, 7 ex, 1 tbl |
