Abstract

A chemically-modified mixed fuel has been produced, wherein at least part of the fuel is a) cost-efficient, b) renewable and/or a consistent resource (e.g. biogenic fuels), c) easy to use, d) easy to transport and e) relatively “clean” with respect to the amount of time/resources it requires to convert the fuel to a “useable” form. Specifically, a chemically-modified mixed fuel has been developed that comprises methane gas from at least two methane-production sources. In addition, this chemically-modified mixed fuel can be utilized in any process that incorporates a Kellogg Primary Reformer. A method for producing the chemically-modified mixed fuel described herein comprises a) providing a first methane-containing gas from a first methane-production source, b) providing a second methane-containing gas from a second methane-production source, c) blending the first methane-containing gas with the second methane-containing gas at a suitable pressure to form a chemically-modified mixed fuel. In additional embodiments, 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 two methane-production sources.

2. The chemically-modified fuel of claim 1, wherein the at least two sources comprises at least one fossil source, at least one biogenic source, at least one abiogenic source or a combination thereof.

3. The chemically-modified fuel of claim 2, wherein the at least two sources comprises at least one fossil source and at least one biogenic source.

4. The chemically-modified fuel of claim 3, wherein the at least two sources consists of at least one fossil source and at least one biogenic source.

5. The chemically-modified fuel of claim 2, wherein the at least one biogenic source comprises landfill gas.

6. The chemically-modified fuel of claim 1, wherein at least one of the methane-production sources comprises natural gas, Area-6 gas, landfill gas or a combination thereof.

7. The chemically-modified fuel of claim 1, wherein the percentage of methane in each of the at least two methane-production sources is greater than about 40%.

8. The chemically-modified fuel of claim 1, wherein the percentage of methane in each of the at least two methane-production sources is greater than about 50%.

9. The chemically-modified fuel of claim 1, wherein the percentage of methane in at least one of the at least two methane-production sources is greater than about 70%.

10. A fuel-burning process, comprising:

a Kellogg Primary Reformer System, and

a chemically-modified mixed fuel, wherein the fuel comprises methane gas from at least two methane-production sources.

11. The chemically-modified fuel of claim 10, wherein at least one of the methane-production sources comprises natural gas, Area-6 gas, landfill gas or a combination thereof.

12. A method for producing the chemically-modified mixed fuel, comprising:

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.

13. The method of claim 12, further comprising at least one additional methane-containing gas which is provided from at least one additional methane-production source and blended with the chemically-modified fuel.

14. The method of claim 12, wherein the first methane-production source and the second methane-production source comprise at least one fossil source, at least one biogenic source, at least one abiogenic source or a combination thereof.

15. The method of claim 14, wherein the first methane-production source and the second methane-production source comprise at least one fossil source and at least one biogenic source.

16. The method of claim 15, wherein the first methane-production source and the second methane-production source comprise consists of at least one fossil source and at least one biogenic source.

17. The method of claim 14, wherein the at least one biogenic source comprises landfill gas.

18. The method of claim 13, wherein the percentage of methane in each of the at least two methane-production sources is greater than about 40%.

19. The method of claim 13, wherein the percentage of methane in each of the at least two methane-production sources is greater than about 50%.

20. The method of claim 13, wherein the percentage of methane in at least one of the at least two methane-production sources is greater than about 70%.
