摘要： [Problem] To provide a gas production device that makes it possible to raise the temperature of a reaction unit by separating a removal unit from a reactor and that can efficiently generate a valuable carbon substance.
[Solution] Provided according to one aspect of the present invention is a gas production device. This gas production device has at least two reactors and a removal unit. The two reactors are connected in series and are configured to be capable of supplying an oxidizing gas that contains carbon dioxide and a reducing gas that contains a reducing substance. Each of the reactors accommodates a metal and/or a metal oxide. The metal and/or metal oxide promotes the 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.-

摘要： 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.-

摘要： Provided are a reactor that can operate stably without being subject to restrictions on heating temperature, a gas production apparatus (that is, an industrially advantageous gas production apparatus) having the reactor, a gas production system, and a gas production method.
Each of reactors 4a and 4b includes a container 41 having a single internal space 410 through which gas is capable of passing and a reducing agent layer 42 with which the internal space 410 is filled and which is configured by a reducing agent 4R reducing carbon dioxide to carbon monoxide. When the container 41 is cut in a direction orthogonal to a passage direction of the gas, a proportion of a cross-sectional area of the reducing agent layer 41 to a cross-sectional area of the internal space 410 is equal to or greater than 60%.-

摘要： A gas production device 1 comprises a connection unit 2 for supplying an exhaust gas including carbon dioxide CO 2 , a reducing gas supply unit 3 that supplies a reducing gas including H 2 that reduces a reducing agent 4R that has been brought into an oxidized state by contact with the carbon dioxide CO 2 , the reducing agent including a metal oxide that generates CO by reducing the carbon dioxide CO 2 , and a reaction unit 4 provided with a plurality of reactors 4a to 4d connected respectively to the connection unit 2 and the reducing gas supply unit 3, and with the educing agent 4R that is contained in each of the reactors 4a to 4d, in which the reaction unit 4 being capable of switching between the oxidizing gas and the reducing gas to be supplied to each of the reactors 4a to 4d. The plurality of reactors 4a to 4d include first reactors and second reactors to which the reducing gas is supplied when the oxidizing gas is supplied to the first reactors, and the number of the first reactors is two or more and/or the number of the second reactors is two or more.
