Abstract: An improved metal gas separation membrane for separating hydrogen from a gas steam includes a quantity of metal particles that are bonded together to form a porous body. The porous body may have a porosity that increases from a first surface to an opposite second surface and may additionally include a coating of ceramic particles on the first surface. The metal gas separation membrane may include a coating of a dense precious metal applied thereto that is permeable by hydrogen via chemisorption-dissociation-diffusion. The porous body may include a catalytic enhancement. Also disclosed are three gas separation modules that employ the metal gas separation membrane disposed within a core of the gas separation module for separating hydrogen from a gas stream. The gas separation membranes are each supported on a first mounting member and a second mounting member. The gas separation modules may also include a catalytic enhancement.

Abstract: A ceramic honeycomb structure includes a plurality of through-holes surrounded by partition walls, wherein a thermal expansion coefficient of an outer circumferential wall portion in the ceramic honeycomb structure is larger than a thermal expansion coefficient in a direction of a diameter of an inside partition wall portion 5 in the ceramic honeycomb structure, and stress is applied to the inside partition wall portion from the outer circumferential wall portion. An outer circumferential wall portion of the ceramic honeycomb structure is reinforced, and the ceramic honeycomb structure does not hinder a flow of gas in a circumferential partition wall portion of the ceramic honeycomb structure, and thermal shock resistance of the ceramic honeycomb structure is enhanced profitably.

Abstract: A metal carrier for a catalyst having a cylindrical case with an excellent high temperature oxidation resistance. A metal carrier for the catalyst includes a honeycomb structure which is in a cylindrical form and has plural air vents extending in an axial direction. The cylindrical case covers the periphery of the honeycomb structure. The cylindrical case is made of ferritic stainless steel containing Mo. The present invention makes it possible to avoid the occurrence of abnormal oxidation of the cylindrical case at high temperature.
