Abstract
Provided are a non-pyrophoric water gas shift reaction catalyst including: an oxide carrier composed of zirconium oxide (ZrO2) and at least one selected from yttrium oxide (Y2O3) and cerium oxide (CeO2); and platinum (Pt) and cerium (Ce) that are supported on the oxide carrier, a method of preparing the same, and a fuel processor including the non-pyrophoric water gas shift reaction catalyst.
Claims8
A non-pyrophoric water gas shift reaction catalyst comprising:
- an oxide carrier consisting of zirconium oxide (ZrO2) and cerium oxide (CeO2);
- and platinum (Pt) and cerium (Ce) oxide that are supported on the oxide carrier, wherein the amount of the zirconium oxide (ZrO2) is in a range of 50 to 95 parts by weight based on 100 parts by weight of the oxide carrier, and wherein a molar mixing ratio of the Ce supported on the oxide carrier to Pt supported on the oxide carrier is in a range of 10:1 to 15:1 such that an activity of the non-pyrophoric water gas shift reaction catalyst at a temperature in a range of 230° C. or lower in a reformer of a fuel processor is improved in comparison to the activity of a non-pyrophoric water gas shift reaction catalyst at a temperature in a range of 230° C. in a reformer of a fuel processor in which the molar mixing ratio of Ce to Pt is not in a range of 10:1 to 15:1.
