Abstract

A chemically-modified mixed fuel includes methane gas from at least two methane-production sources and can be utilized in any process that incorporates a Kellogg Primary Reformer. A method for producing the chemically-modified mixed fuel described herein includes providing a first methane-containing gas from a first methane-production source, providing a second methane-containing gas from a second methane-production source and blending the first methane-containing gas with the second methane-containing gas at a suitable pressure to form a chemically-modified mixed fuel. In some cases, at least one additional methane-containing gas can be provided from at least one additional methane-production source and blended with the chemically-modified fuel.

Claims

1. A chemically-modified mixed fuel, wherein the fuel comprises methane gas from at least one fossil source, at least one biogenic source, and at least one abiogenic source.

2. The chemically-modified fuel of claim 1, wherein the biogenic source comprises landfill gas.

3. The chemically-modified fuel of claim 1, wherein the percentage of methane in each of the at least one fossil methane-production source and at least one biogenic methane-production source is greater than about 40%.

4. The chemically-modified fuel of claim 1, wherein the percentage of methane in each of the at least one fossil methane-production source and at least one biogenic methane-production source is greater than about 50%.

5. The chemically-modified fuel of claim 2, wherein the percentage of methane in the at least one fossil source is greater than about 70%.

6. The chemically-modified fuel of claim 2, wherein the landfill gas is at least about 40% methane.

7. The chemically-modified fuel of claim 2, wherein the ratio by volume of the at least one fossil source to the at least one biogenic source is from about 9430:

3000 to about 6500;

3000.

8. The chemically-modified fuel of claim 1, wherein the at least one abiogenic methane-production source comprises about 17% to about 25% methane.

9. The chemically-modified fuel of claim 8, wherein the ratio by volume of the at least one fossil source to the at least one biogenic source to the at least one abiogenic methane-production source is from about 9430:

3000;

2900 to about 6500;

3000;

2000.

10. The chemically-modified fuel of claim 1, wherein the ratio by volume of the at least one fossil source to at least one biogenic source to the at least one abiogenic methane-production source is from about 9430:

3000;

2900 to about 6500;

3000;

2000.

11. The chemically-modified fuel of claim 1, wherein the at least one abiogenic methane-production source comprises about 43% hydrogen.

12. The chemically-modified fuel of claim 1, wherein the at least one fossil source comprises about 70 to about 90% methane, the at least one-biogenic source comprises about 45% to about 50% methane, and the at least one abiogenic methane-production source comprises about 17% to about 25% methane.

13. The chemically-modified fuel of claim 1, wherein the at least one fossil source comprises about 70 to about 90% methane, the at least one-biogenic source comprises about 45% to about 50% methane, and the at least one abiogenic methane-production source comprises about 17% methane.

14. The chemically-modified fuel of claim 13, wherein the at least one abiogenic methane-production source comprises about 43% hydrogen and about 40% nitrogen.
