Hydrocarbon-based fuel reforming catalyst and production method therefor

Abstract

A hydrocarbon-based fuel reforming catalyst that suffers less capability deterioration and has excellent heat resistance and excellent durability is disclosed. The reforming catalyst includes CuOx/ZnO/ZrO2/MnOx or CuOx/ZnO/ZrO2/Y2O3 formed by adding manganese or yttrium to a reforming catalyst composed of copper, zinc and zirconium. If manganese is added, the ratio of manganese to the sum of manganese and zirconium (n/(Mn+Zr)) is from about 0.1 to about 0.62 and, preferably, about 0.17 to about 0.5, and the ratio of copper to the sum of copper and zinc (Cu/(Cu+Zn)) is from about 0.2 to about 0.6 and, preferably, about 0.3 to about 0.48. The reforming catalyst exhibits less capability deterioration and good durability in the steam reforming reaction of methanol.
