Gas production equipment, gas production system and gas production method

摘要

PROBLEM TO BE SOLVED: To provide a gas production apparatus and a gas production system capable of continuously and stably producing a produced gas containing carbon monoxide from a raw material gas containing carbon dioxide. A gas production apparatus 1 is an apparatus for producing a produced gas containing carbon monoxide by bringing a raw material gas containing carbon dioxide into contact with a reducing agent containing a metal oxide that reduces carbon dioxide. It is provided with a plurality of reactors 4a and 4b and a reducing agent arranged in the reactors 4a and 4b, and has a reaction unit 4 capable of switching between a raw material gas and a reducing gas supplied to each of the reactors 4a and 4b. Then, when a predetermined amount of raw material gas is supplied to the reactors 4a and 4b, or when the conversion efficiency of carbon dioxide to carbon monoxide falls below a predetermined value, the raw material to be supplied to the reactors 4a and 4b. It was configured to switch between gas and carbon dioxide. [Selection diagram] Fig. 1
