摘要：
A method for producing a conjugated diene according to one aspect of the present invention comprises a step of contacting a raw material gas containing an alkane with a first catalyst and a second catalyst in this order to obtain a product gas containing a conjugated diene. In the production method, the first catalyst contains Sn and Pt, and a content of Sn in the first catalyst is less than 12% by mass based on the total mass of the first catalyst; and the second catalyst contains Sn and Pt, and a content of Sn in the second catalyst is 12% by mass or more based on the total mass of the second catalyst.
