Method for producing catalyst for dehydrogenation aromatization reaction of methane and aromatic compound

摘要

PROBLEM TO BE SOLVED: To select a catalyst for dehydrogenation aromatization reaction of methane, a method for producing the catalyst, and an aromatic compound (particularly benzene), which achieve a high conversion rate and selectivity for the dehydrogenation aromatization reaction of methane. Provide a method of manufacturing. Tungsten carbide M-WCx (formula) doped with at least one metal M selected from the group consisting of Group 4 metals (Ti, Zr, Hf) and Group 5 metals (V, Nb, Ta). Among them, x represents a numerical value of 0.82 to 1.00.) A catalyst for dehydrogenating aromaization reaction of methane, which comprises a metallosilicate carrying (), and metallosilicate at least one metal M compound. A method for producing the catalyst, which comprises a step of forming a composite oxide of tungsten and metal M and a step of heat-treating the catalyst precursor at a temperature of 500 to 900 ° C. in the presence of methane to carbonize the catalyst precursor. A method for producing an aromatic compound that decarbides and aromaticizes methane using a catalyst. [Selection diagram] None
