Abstract
A method for producing diene in which diene can be produced in a high yield by using a raw material including a branched olefin and a straight chain olefin is provided. The method for producing diene comprises: a step 1 of obtaining an internal olefin by removing a branched olefin from a raw material including at least the branched olefin and a straight chain olefin; a step 2 of isomerizing the internal olefin to a terminal olefin by using an isomerization catalyst; and a step 3 of producing diene from the terminal olefin obtained in the step 2 by oxidative dehydrogenation using a dehydrogenation catalyst.
