(b) methane in an amount in a range of 5 to 70 volume percent based on a total volume of the gaseous fuel mixture; and
wherein the gaseous fuel mixture comprises less than 1000 parts per million (volume/volume) carbon monoxide; and
a refillable gas cylinder comprising a non-corrosive container and a valve that is connected to the non-corrosive container and that is suitable for use with a hydrogen-containing gas, wherein the gaseous fuel mixture is positioned within the non-corrosive container;
wherein the gaseous fuel micture burns without creating soot or carbon buildup.
2. The article of claim 1 , wherein the gaseous fuel mixture comprises 75 to 95 volume percent hydrogen and 5 to 25 volume percent methane.
3. The article of claim 1 , wherein the gaseous fuel mixture comprises 85 to 95 volume percent hydrogen and 5 to 15 volume percent methane.
4. The article of claim 1 , wherein the gaseous fuel mixture further comprises a mercapto-containing compound.
5. The article of claim 4 , wherein the mercapto-containing compound is methyl mercaptan.
6. The article of claim 1 , wherein the non-corrosive container comprises aluminum or an aluminum alloy.
7. The article of claim 1 , wherein the gas cylinder further comprises polymeric sleeve arranged on a portion of container.
8. The article of claim 1 , wherein the fuel mixture is free or essentially free of acetylene, acetone, dimethyl formamide, N-methylpyrrolidinone, or mixtures thereof.
9. The article of claim 1 , wherein the fuel mixture is free or essentially free of a solid filler material.
10. The article of claim 1 , further comprising a protective guard surrounding the valve, wherein the protective guard is configured for use as a handle for carrying the gas cylinder.
11. The article of claim 1 , wherein the valve is suitable for discharging the fuel mixture and for refilling the gas cylinder with additional fuel mixture after discharging.
12. The article of claim 1 , further comprising a gas regulator and a torch suitable for cutting metal, brazing metal, or soldering metal, wherein the regulator has a first end connected to the valve and a second end connected to the torch.
13. The article of claim 12 , further comprising a gas cylinder containing an oxygen-containing gas connected to the torch.
14. The article of claim 1 , wherein at least 99.3 volume percent of the gaseous fuel mixture is hydrogen and methane.
15. The article of claim 1 , wherein the gaseous fuel mixture comprises less than 500 parts per million carbon monoxide.
16. An article comprising:
a gaseous fuel mixture comprising
(a) hydrogen in an amount in a range of 70 to 95 volume percent based on a total volume of the gaseous fuel mixture;
(b) methane in an amount in a range of 5 to 30 volume percent based on a total volume of the gaseous fuel mixture; and
(c) a mercaptan compound in an amount in a range of 0.1 to 100 parts per million (volume/volume); and
wherein the gaseous fuel mixture comprises less than 1000 parts per million (volume/volume) carbon monoxide; and
a refillable gas cylinder comprising a non-corrosive container comprising aluminum and a valve that is connected to the non-corrosive container and that is suitable for use with a hydrogen-containing gas, wherein the gaseous fuel mixture is positioned within the non-corrosive container;
wherein the gaseous fuel mixture burns without creating soot or carbon buildup.
17. The article of claim 16 , wherein the gaseous fuel mixture comprises 85 to 95 volume percent hydrogen and 5 to 15 volume percent methane.
18. The article of claim 16 , further comprising a gas regulator and a torch suitable for cutting metal, brazing metal, or soldering metal, wherein the regulator has a first end connected to the valve and a second end connected to the torch.
19. The article of claim 18 , further comprising a gas cylinder containing an oxygen-containing gas connected to the torch.
20. The article of claim 16 , wherein the gaseous fuel mixture comprises less than 500 parts per million carbon monoxide.
21. A gaseous fuel mixture suitable for use in a refillable gas cylinder comprising a non-corrosive container and a valve that is connected to the non-corrosive container,
the gaseous mixture comprising:
(a) hydrogen in an amount in a range of 30 to 95 volume percent based on a total volume of the gaseous fuel mixture; and
(b) methane in an amount in a range of 5 to 70 volume percent based on a total volume of the gaseous fuel mixture;
wherein the gaseous fuel mixture comprises less than 1000 parts per million (volume/volume) of carbon monoxide;
wherein the gaseous fuel mixture burns without creating soot or carbon buildup.
22. The gaseous fuel mixture of claim 21 , wherein the gaseous fuel mixture comprises less than 500 parts per million carbon monoxide.
