Steam reforming catalyst structure, reforming apparatus provided with the steam reforming catalyst structure, and method for producing steam reforming catalyst structure

摘要

A steam reforming catalyst structure capable of efficiently generating a reformed gas containing hydrogen from a reforming raw material containing hydrocarbons by maintaining good catalytic activity by suppressing agglomeration of catalyst particles, and a modified structure using the same. Provides quality equipment. The steam reforming catalyst structure (1) of the present invention is a steam reforming catalyst structure (1) used for producing a reformed gas containing hydrogen from a reforming raw material containing a hydrocarbon, A passage (11) comprising a carrier (10) having a porous structure composed of a zeolite type compound and at least one catalyst substance (20) contained in the carrier (10), wherein the carrier (10) communicates with each other. And the catalyst substance (20) is metal fine particles, and is present in at least the passage (11) of the carrier (10).
