REFORMING CATALYST FOR OXYGEN-CONTAINING HYDROCARBON, METHOD FOR PRODUCING HYDROGEN OR SYNTHESIS GAS USING SAME, AND FUEL CELL SYSTEM

摘要

Disclosed is a reforming catalyst for oxygen-containing hydrocarbons which contains copper, a metal oxide having a spinel structure and a zeolite. Preferably, the reforming catalyst further contains alumina, a group VIII metal or a rare earth element. Also disclosed is a method for producing hydrogen or a synthesis gas by subjecting an oxygen-containing hydrocarbon to (1) steam reforming, (2) autothermal reforming, (3) partial oxidation reforming or (4) carbon dioxide reforming, while using the above-described reforming catalyst. Further disclosed is a fuel cell system using the reforming catalyst. The reforming catalyst has a high activity and excellent heat resistance. When the reforming catalyst further contains alumina, a group VIII metal or a rare earth element, the amount of coke generation is suppressed, thereby further improving durability of the catalyst. Consequently, hydrogen or a synthesis gas can be efficiently produced by subjecting an oxygen-containing hydrocarbon to various reforming using such a reforming catalyst, and thus the reforming catalyst is used in a fuel cell system or the like.
