Carbon dioxide reforming catalyst, method of manufacture, carbon dioxide reforming carrier of catalyst, reformer, and a manufacturing method of synthesis gas

摘要

PROBLEM TO BE SOLVED: To provide a carbon dioxide reforming catalyst capable of efficiently producing hydrogen and carbon monoxide by making a hydrocarbon-based raw material gas react with carbon monoxide while suppressing carbon deposition and to provide a production method thereof.;SOLUTION: The carbon dioxide reforming catalyst has a composition containing at least one carbonate of an alkaline earth metal selected from the group consisting of Ca, Sr, and Ba, a catalyst metal which promotes the decomposition reaction of a hydrocarbon-based raw material gas, and a complex oxide containing at least one alkaline earth metal selected from the group consisting of Ca, Sr, and Ba and at least one component selected from the group consisting of Al, Zr, Fe, W, and Mo. The complex oxide is AAl₂O₄, AZrO₃, AFe₂O₄, A₃W₂O₉, A₂WO₅, or AMoO₄ (wherein A is at least one alkaline earth metal selected from the group consisting of Ca, Sr, and Ba).;COPYRIGHT: (C)2010,JPO&INPIT
