Abstract

A butadiene production system and a butadiene production method are provided in which butadiene can be produced with a high yield. The butadiene production system () includes: a gas preparation device () that heats raw materials to prepare a mixed gas including hydrogen and carbon monoxide; an ethanol production device () that is provided downstream of the gas preparation device () and brings the mixed gas including hydrogen and carbon monoxide into contact with a first catalyst to obtain ethanol; a butadiene production device () that is provided downstream of the ethanol production device () and brings the ethanol into contact with a second catalyst to obtain butadiene; and return means () for returning hydrogen, which is produced as a by-product in the butadiene production device (), to the ethanol production device (). In addition, in the butadiene production method, the butadiene production system () is used.
