Abstract
A catalyst for synthesizing a conjugated diene from a raw material including an alcohol, which includes at least Ce and Zn as metal elements constituting the catalyst. An apparatus for producing a conjugated diene, including: a reaction tube () provided with the catalyst; a supply means for supplying a raw material gas containing the raw material into the reaction tube (); and an outlet means for releasing a product from the reaction tube (). A method for producing a conjugated diene, including contacting a raw material gas containing a raw material with the catalyst to obtain a conjugated diene. The amount of the raw material is preferably 10 to 50% by volume (in terms of gas volume) with respect to 100% by volume (in terms of gas volume) of the raw material gas.
