Hydrogen from Methane: Is it Possible?

[elixer akm]

Is there any possibility of getting hydrogen from methane,since it contain 4 hydrogen atom per molecule...

 

[Drakkith]

Certainly. See here: https://energy.gov/eere/fuelcells/hydrogen-production-natural-gas-reforming

Yes ...involves the use of steam at high temperatures ,an industrial process , not suited for home production
CH4 + H2O → CO + 3 H2
CO + H2O → CO2 + H2

An easy way to produce at home is the reaction of aluminium and sodium hydroxide , both easily obtained.

So my questio is why its not used for industrial production of hydrogen...we can use it as propellant in rocket

 

[Borek]

why its not used

Where did you got the information that it is not used from?

Did you not read the link I gave?

Sorry i didnt see that ...and that's what i looking for thanks...

the link says "Today, 95% of the hydrogen produced in the United States is made by natural gas reforming in large central plants" ...

There's not a big demand for H as a rocket fuel , not many people have rockets ...used in industry to make ammonia hydrochloric acid ...

There are other ways to extract hydrogen from natural gas, with solid carbon as the waste product. One way is called methane pyrolysis.
Fossil fuels are a potentially abundant source of hydrogen, which can be separated from natural gas with solid carbon as the waste product. The process is called methane pyrolysis. Can also work on any other hydrocarbon including waste plastic. Chemical company BASF has a pilot plant in Germany, see https://tinyurl.com/2hk8tzzv Another approach is to heat catalysts with microwave energy in the presence of natural gas. Go to the 29:10 mark in the following video: There are other approaches as well. Finally, it appears that hydrogen is trapped in the Earth's crust and can be drilled out. If such natural hydrogen is abundant, this would probably be the cheapest source of hydrogen. See Cheers !
