A method for producing a structure catalyst and a method for producing hydrogen using a structure catalyst.

摘要

Provided is a method for producing a structure catalyst for generating a high-concentration hydrogen gas by a water-gas shift reaction from a gas containing hydrogen and carbon monoxide. The method for producing the structure catalyst includes an anoxidation step (S1) in which the surface of the aluminum substrate is annotated to form an alumina carrier, and a first immersion step in which the alumina carrier is immersed in an aqueous solution containing a catalyst component. (S4), the first firing step (S5) in which the alumina carrier on which a partial amount of the catalyst component is supported in the first immersion step is fired in a temperature range of 120 to 500 ° C. in an oxidizing atmosphere, and the above. A second dipping step (S6) in which the alumina carrier that has undergone the first firing step is immersed in an aqueous solution containing the catalyst component, and the alumina in which the final amount of the catalyst component is supported in the second dipping step. The second firing step (S7) of firing the carrier in a temperature range of 120 to 500 ° C. in an oxidizing atmosphere is performed.
