    摘要: The present invention provides a method for producing a catalyst for use in preferential carbon monoxide oxidation, which catalyst has a high preferential carbon monoxide oxidation activity and a high methanation activity with respect to the carbon monoxide contained in hydrogen gas, can thus stably reduce the carbon monoxide concentration to an extremely lower level and comprises porous inorganic oxide support particles and, on the basis of the mass thereof, 0.01 to 10 percent by mass of ruthenium and 0.01 to 1 percent by mass of platinum, loaded on the support. The method comprises (1) a step of loading 30 to 70 percent of the total amount of ruthenium to be loaded, on the support particles by a competitive adsorption method and (2) a step of loading the rest of the total amount of ruthenium to be loaded and the total amount of platinum to be loaded, on the ruthenium-loaded support particles produced in step (1) without using a competitive adsorption agent.

    摘要: The present invention provides a hydrogen production method capable of producing hydrogen with good efficiency while solving problems such as separation, lower-temperature reaction and heat supply in production of hydrogen by dehydrogenation reaction of raw material oil. Within a reaction tube of a double-tube structure comprising an inner tube composed of a hydrogen separating membrane, a metallic outer tube having a plurality of internal fins, and a metal oxide layer and further a catalyst supported on the fins, hydrocarbon having cyclohexane ring is dehydrogenated to produce hydrogen and aromatic hydrocarbon, and selective membrane separating operation of hydrogen is performed within the reaction system while conducting the dehydrogenation to remove mainly the hydrogen on a permeating side and obtain mainly the aromatic hydrocarbon on a non-permeating side. The other method comprises absorbing at least part of the resulting hydrogen flow to a hydrogen absorbing (storing) alloy to make the pressure on the hydrogen permeating side of the hydrogen separating membrane lower than that on the non-permeating side.
