Abstract: A gas adsorption system includes a plurality of gas adsorption units each including an electrochemical device configured to adsorb and release a predetermined gas. The plurality of gas adsorption units include: a first adsorption unit to which the predetermined gas is supplied; and a second adsorption unit to which the gas having passed through the first adsorption unit is supplied.

Abstract: A reactor includes a second flow path on a permeation side of a separate membrane. The second flow path includes an inflow port open to a first space between a first seal portion and a flow stop unit, and an outflow port open to a second space between a second seal portion and a flow stop unit. A housing includes a sweep gas supply port for supplying a sweep gas to the first space and a sweep gas exhaust port for discharging the sweep gas from the second space. In a side view of the reactor, a direction in which the sweep gas flows through the second space is opposite to a direction in which the sweep gas flows through the second flow path.

Abstract: A reactor includes a second flow path on a permeation side of a separation membrane. The second flow path includes an inflow port open to a first space between a first seal portion and a flow rate adjustment unit, and an outflow port open to a second space between a second seal portion and a flow rate adjustment unit. A housing includes a sweep gas supply port for supplying a sweep gas to the first space and a sweep gas exhaust port for discharging the sweep gas from the second space. In a side view of the reactor, a direction in which the sweep gas flows from the first space to the second space via the flow rate adjustment unit is the same as a direction in which the sweep gas flows through the second flow path.

Abstract: A liquid fuel synthesis system includes a liquid fuel synthesis unit and a sweep gas supply unit. The liquid fuel synthesis unit is permeable to a product of a conversion reaction of a raw material gas containing at least hydrogen and carbon dioxide to a liquid fuel. The sweep gas supply unit for supplying a sweep gas for sweeping the product has permeating through the separation membrane to the liquid fuel synthesis unit. The sweep gas contains hydrogen or carbon dioxide as a main component.

Abstract: A membrane reactor includes a catalyst layer, a separation membrane, and a buffer layer. The catalyst layer contains a catalyst for promoting a conversion reaction from a feed gas containing hydrogen and carbon oxide to a liquid fuel. The separation membrane is permeable to water vapor which is a byproduct of the conversion reaction. The buffer layer is disposed between the separation membrane and the catalyst layer, and permeable to the water vapor toward the separation membrane.

Abstract: A liquid fuel synthesis system includes a liquid fuel synthesis portion and a sweep gas supply unit. The liquid fuel synthesis portion is partitioned into a non-permeation side space and a permeation side space by the separation membrane. A temperature of the sweep gas flowing into the permeation side space is higher than at least one of a temperature of the raw material gas flowing into the non-permeation side space and a temperature of a first outflow gas flowing out of the non-permeation side space. A temperature of a second outflow gas flowing out of the permeation side space is higher than at least one of the temperature of the raw material gas flowing into the non-permeation side space and the temperature of the first outflow gas flowing out of the non-permeation side space.
