Abstract
A method for producing a conjugated diene according to an aspect of the present invention comprises a step of contacting a raw material gas containing an alkane with a dehydrogenation catalyst to obtain a product gas containing at least one unsaturated hydrocarbon selected from the group consisting of an olefin and a conjugated diene. In the production method, the dehydrogenation catalyst is a catalyst having a supported metal containing a Group 14 metal element and Pt supported on a support containing Al and a Group 2 metal element; the dehydrogenation catalyst has pores (a) having a pore diameter of 7 nm or more and 32 nm or less; and a proportion of a pore volume of the pores (a) is 65% or more of the total pore volume of the dehydrogenation catalyst.
