Steam reforming catalyst for hydrocarbon and method for manufacturing the same.

摘要

In the steam reforming catalyst for hydrocarbon according to the present invention, catalyst metal is supported on or in the surface layer of zirconia carrier containing yttria and having crystal structure primarily consisting of tetragonal system or tetragonal and cubic systems. Compared with conventional type steam reforming catalyst, it has higher reaction efficiency and suppresses carbon deposition extensively even when steam/carbon ratio is low and exhibits higher hydrogen generation efficiency and higher catalyst strength. Particularly, it is suitable as a catalyst for internal reforming type fuel cell. In the steam reforming catalyst of hydrocarbon of this invention, metal catalyst can be effectively utilized by supporting metal catalyst only on surface layer of zirconia carrier.
