Abstract

A hydrocarbon reforming catalyst for producing a synthesis gas containing hydrogen and carbon monoxide from a hydrocarbon-based gas, the hydrocarbon reforming catalyst containing a complex oxide having a perovskite structure including at least Ba, Zr, and Ru; and a hydrocarbon reforming apparatus that includes the hydrocarbon-reforming catalyst.

First claim

The invention claimed is:

1. A hydrocarbon reforming catalyst for producing a synthesis gas containing hydrogen and carbon monoxide from a hydrocarbon-based gas, the hydrocarbon reforming catalyst comprising:
a complex oxide having a perovskite structure including at least Ba, Zr, Ru, and Y,
wherein a molar ratio of Y to Ba is 0.1 to 0.5.

2. The hydrocarbon reforming catalyst according to claim 1 , wherein a molar ratio of the Ru to the Ba is 0.07 or more.

3. The hydrocarbon reforming catalyst according to claim 2 , wherein the molar ratio of the Ru to the Ba is 0.07 to 0.41.

4. The hydrocarbon reforming catalyst according to claim 1 , wherein a molar ratio of the Y to the Ba is 0.2 to 0.4.

5. The hydrocarbon reforming catalyst according to claim 1 , wherein a molar ratio of the Y to the Zr is 0.1 or more.

6. The hydrocarbon reforming catalyst according to claim 5 , wherein the molar ratio of the Y to the Zr is 0.1 to 1.

7. The hydrocarbon reforming catalyst according to claim 1 , wherein a molar ratio of the Y to the Zr is 0.25 to 0.67.

8. The hydrocarbon reforming catalyst according to claim 1 , wherein a molar ratio of a total amount of the Zr and the Y to the Ba is 0.68 to 1.5.

9. The hydrocarbon reforming catalyst according to claim 1 , wherein a molar ratio of the Y to the Zr is 0.1 to 1, and a molar ratio of a total amount of the Zr and the Y to the Ba is 0.68 to 1.5.

10. A hydrocarbon reforming apparatus for treating a gas containing at least a hydrocarbon, the apparatus comprising:
a pipe configured such that the gas containing the at least the hydrocarbon can flow;
a heater positioned to heat the gas as the gas flows through the pipe; and
a hydrocarbon-reforming catalyst disposed so as to contact the gas while the gas is inside the pipe, the hydrocarbon-reforming catalyst containing a complex oxide having a perovskite structure including at least Ba, Zr, Ru, and Y, wherein a molar ratio of Y to Ba is 0.1 to 0.5.

11. The hydrocarbon reforming apparatus according to claim 10 , wherein a molar ratio of the Ru to the Ba is 0.07 to 0.41.

12. The hydrocarbon reforming apparatus according to claim 10 , wherein the molar ratio of the Y to the Zr is 0.1 to 1.

13. The hydrocarbon reforming apparatus according to claim 10 , wherein a molar ratio of the Y to the Zr is 0.1 to 1, and a molar ratio of a total amount of the Zr and the Y to the Ba is 0.68 to 1.5.

14. The hydrocarbon reforming apparatus according to claim 10 , further comprising a hydrocarbon supply source that is disposed on an upstream side of the pipe and is constructed to supply the hydrocarbon.

15. The hydrocarbon reforming apparatus according to claim 10 , further comprising a hydrogen extraction outlet disposed on a downstream side of the pipe.
