Is there a way to separate hydrogen from natural gas (CH4)? The reason I ask is there are a couple of guys who use this combination to produce synthetic diamonds,
Link.
During the process carbon precipitates out of the gas to form diamond which leaves a mixture of more hydrogen and less natural gas than at the start. Separating the two would yield a byproduct of hydrogen which could then be sold. I dont know how much more hydrogen would be produced, I suppose it would be proportional to the size of the diamond being produced. Eventually the 'diamond growers' want to be able to make diamond wafers which could be cut up for semiconductors. At high production rates that could mean a great deal of hydrogen being produced.
Any ideas how to separate gases?
