PROBLEM TO BE SOLVED: To obtain ethylene in a high selectively and in a high yield without using an expensive element and without adding a halogen, etc., to the reaction system, by bringing ethane into contact with a molecular oxygen-containing gas in the presence of a catalyst containing a specific composite metal oxide at a high temperature. SOLUTION: This method for producing ethylene comprises bringing ethane into contact with a molecular oxygen-containing gas at a temperature of 250-500 deg.C in the presence of a catalyst containing a composite metal oxide containing Mo, V and Sb as essential components and having a powder X-ray diffraction mainly having a characteristic pattern of the table. The composite metal oxide is obtained by adding a Mo-containing compound and a compound containing an element such as Ti or Zr to an aqueous solution containing a V-containing component and a Sb-containing component, drying the aqueous solution and subsequently calcining the obtained catalyst precursor. |
