Abstract
A gas production device and a gas production system capable of efficiently manufacturing a produced gas containing carbon monoxide from a raw material gas containing carbon dioxide are provided. The gas production device manufactures a produced gas containing carbon monoxide by bringing a raw material gas containing carbon dioxide into contact with a reductant that reduces the carbon dioxide. The device includes a connecting portion supplying the raw material gas, a reducing gas supply section supplying a reducing gas for reducing the reductant oxidized by contact with the carbon dioxide, a reaction section including a plurality of reactors, to which the connecting portion and the reducing gas supply section are respectively connected, and the reductant arranged in the reactors, and a concentration adjustment section provided between the connecting portion and the reactors and adjusting a concentration of oxygen contained in the raw material gas to less than 1% by volume.
