    Abstract: A reactor includes a separation membrane, a non-permeation side flow path and a catalyst. The separation membrane is permeable to a product of a conversion reaction in which a raw material gas containing at least hydrogen and carbon oxide is converted to a liquid fuel. The non-permeation side flow path is provided on a non-permeation side of the separation membrane, the raw material gas flowing through the non-permeation side flow path. The catalyst is provided in the non-permeation side flow path and configured to promote the conversion reaction. The catalyst includes catalyst particles each constituted by a carrier and a supported catalytic component, and filler particles softer than the catalyst particles.

    Abstract: A monolith-type reactor includes a porous support body, a plurality of first cells through which a raw material gas flows, a plurality of second cells through which the sweep gas flows, separation membranes, and a catalyst. The first cells pass through the porous support body in a first direction. The second cells extend in the porous support body in the first direction. The separate membranes are respectively formed on inner peripheral surfaces of the first cells and permeable to a product of the conversion reaction. The catalyst is arranged inside the separation membranes, and promotes the conversion reaction. In a cross section taken along a second direction perpendicular to the first direction, the average cross-sectional area of the first cells is larger than the average cross-sectional area of the second cells.

    Abstract: A reactor includes a separation membrane permeable to a product of a conversion reaction of a raw material gas containing at least hydrogen and carbon oxide to a liquid fuel, a non-permeation side flow path extending in an approximately vertical direction on a non-permeation side of the separation membrane, the raw material gas flowing through the non-permeation side flow path, and a catalyst configured to fill the non-permeation side flow path and promote the conversion reaction. The catalyst includes a first layer and a second layer disposed upward of the first layer, and a mean equivalent circle diameter of catalyst particles included in the first layer is larger than a mean equivalent circle diameter of catalyst particles included in the second layer.

    Abstract: A methane production system includes a co-electrolysis/reforming cell and a control unit that controls operating temperatures of the co-electrolysis/reforming cell. The co-electrolysis/reforming cell includes a first electrode, a second electrode, and an electrolyte disposed between the first electrode and the second electrode. The co-electrolysis/reforming cell operates in either a co-electrolysis mode in which H2 and CO are produced at the first electrode from CO2 and H2O, or a reforming mode in which CH4 is produced at the first electrode from the H2 and CO produced in the co-electrolysis mode. The control unit makes an operating temperature of the co-electrolysis/reforming cell in the reforming mode lower than an operating temperature of the co-electrolysis/reforming cell in the co-electrolysis mode.

    Abstract: A reactor module includes a pre-reactor and a membrane reactor disposed downstream of the pre-reactor. The membrane reactor includes a separation membrane. In the pre-reactor, an intermediate gas is generated from a source gas containing hydrogen and carbon oxide. The intermediate gas contains a liquid fuel, water vapor, and residual source gas. In the membrane reactor, the liquid fuel and water vapor are generated from the residual source gas. The separation membrane allows the water vapor contained in the intermediate gas and a product generated from the residual source gas to pass therethrough.
