Gas production apparatus, gas production system, and gas production method

Abstract

Provided are a gas production apparatus (that is, an industrially advantageous gas production apparatus), a gas production system, and a gas production method that can easily and accurately determine the timing to end a reaction and can operate stably. A gas production apparatus 1 includes: reactors 4a and 4b each of which includes a container 41 through which a substrate gas is capable of passing and a reducing agent layer (packed bed) 42 with which the container 41 is filled and which includes a metal oxide that exchanges oxygen elements with the substrate gas by an exothermic reaction or an endothermic reaction; and a plurality of temperature sensors 4T1 to 4T4 that are connected to each of the reactors 4a and 4b and measure temperatures of a plurality of measurement points of the packed bed 42 along a passage direction of the substrate gas, respectively. When a length of the packed bed 42 along the passage direction of the substrate gas is H, an interval between adjacent measurement points is equal to or less than H/3.
