Abstract

A gas production device that makes it possible to raise the temperature of a reaction unit by separating a removal unit from a reactor. The device has at least two reactors and a removal unit. The two reactors are connected in series and are configured to supply an oxidizing gas containing carbon dioxide, and a reducing gas containing a reducing substance. Each of the reactors accommodates a metal and/or a metal oxide which promotes reduction of the carbon dioxide or the reaction between the carbon dioxide and the reducing substance, thereby generating a valuable carbon substance. The removal unit is connected between the two reactors and has a phase separation mechanism that carries out phase separation of a gaseous component and a separated component including at least one of a liquid component and a solid component produced through cooling, thereby removing products derived from the gas supplied to the reactors.
