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 (34)

1. A fuel burning process, comprising the steps of:

providing a first methane-containing gas from a first methane production source at a first, relatively higher pressure;

providing a second methane-containing gas from a biogenic methane production source at a second, relatively lower pressure;

pressurizing the second methane-containing gas from the second pressure toward the first pressure;

blending the first methane-containing gas with the second methane-containing gas to form a chemically-modified mixed fuel; and

combusting the chemically-modified mixed fuel in arch burners of a primary reformer of a Kellogg Primary Reformer System.

2. The process of claim 1 , further including, after said blending step and prior to said combusting step, the additional step of:

pressurizing the chemically-modified mixed fuel to a pressure higher than the first pressure.

3. The process of claim 2 , wherein said step of pressurizing the chemically-modified mixed fuel further comprises pressurizing the chemically-modified mixed fuel to a pressure of at least 75 psig.

4. The process of claim 1 , wherein said blending step further comprises blending a third, additional methane-containing gas, provided from at least one additional methane production source, into the chemically-modified mixed fuel.

5. The process of claim 1 , wherein the first methane production source comprises at least one fossil fuel source, at least one abiogenic source or a combination thereof.

6. The process of claim 1 , wherein a percentage of methane in said second gas is greater than about 40%.

7. The process of claim 6 , wherein the percentage of methane in said second gas is between 45-50%.

8. The process of claim 6 , wherein the percentage of methane in said first gas is greater than about 70%.

9. The process of claim 6 , wherein the percentage of methane in said first gas is between 70-90%.

10. The process of claim 1 , wherein the second methane containing gas is landfill gas.

11. A fuel burning process, comprising the steps of:

providing a first methane-containing gas from a first methane production source;

providing a second methane-containing gas from a biogenic methane production source;

blending the first methane-containing gas with the second methane-containing gas at a first ratio to form a chemically-modified mixed fuel;

combusting the chemically-modified mixed fuel in arch burners of a primary reformer of a Kellogg Primary Reformer System to provide an energy output; and

adjusting the first ratio of said blending step based on variations in at least one of pressure and heating value of the second methane-containing gas to maintain the energy output.

12. The process of claim 11 , wherein the second methane containing gas is landfill gas.

13. The process of claim 11 , wherein:

said step of providing a second methane-containing gas further comprises providing the second methane-containing gas at a first, relatively lower pressure; and

said blending step further comprises blending the first methane-containing gas with the second methane-containing gas at a second, relatively higher pressure.

14. The process of claim 11 , wherein said blending step further comprises blending a third, additional methane-containing gas, provided from at least one additional methane production source, into the chemically-modified mixed fuel.

15. The process of claim 11 , further including, after said blending step and prior to said combusting step, the additional step of:

pressurizing said chemically-modified mixed fuel to a pressure of at least 75 psig.

16. The process of claim 11 , wherein the first methane production source comprises at least one fossil fuel source, at least one abiogenic source or a combination thereof.

17. The process of claim 11 , wherein a percentage of methane in said second gas is greater than about 40%.

18. The process of claim 17 , wherein the percentage of methane in said second gas is between 45-50%.

19. The process of claim 17 , wherein the percentage of methane in said first gas is greater than about 70%.

20. The process of claim 17 , wherein the percentage of methane in said first gas is between 70-90%.
