    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: In a first step of a method for producing a transparent AlN sintered body, first, a formed body is prepared by forming a mixture obtained by mixing a sintering aid with an AlN raw-material powder containing a plate-like AlN powder whose plate surface is a c-plane and which has an aspect ratio of 3 or more. At this time, the mixture is formed such that the plate surface of the plate-like AlN powder is disposed along a surface of the formed body. In a second step, an oriented AlN sintered body is obtained by subjecting the formed body to hot-press sintering in a non-oxidizing atmosphere while applying a pressure to the surface of the formed body. In a third step, a transparent AlN sintered body is obtained by sintering the oriented AlN sintered body at normal pressure in a non-oxidizing atmosphere to remove a component derived from the sintering aid.

    IPC: B01D65/00

    Abstract: A separation membrane module includes a tubular housing, a columnar membrane structure housed in the housing, an annular first flange surrounding a first end portion of the membrane structure, and a first bonding material interposed between the first flange and the first end portion. The housing has a first facing surface and an inner circumferential surface, the first facing surface facing an end surface of the first flange, and the inner circumferential surface facing an outer circumferential surface of the first flange. A coefficient of thermal expansion of the first bonding material is smaller than a coefficient of thermal expansion of the first flange. A coefficient of thermal expansion of the membrane structure is smaller than the coefficient of thermal expansion of the first flange.

    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.
