When carbon byproducts are produced from these kinds of reactions, are they "pure" carbon, or will there be residues from the impurities in the methane?
The reason I ask is I wonder if the carbon could be used as a soil amendment to help replenish top soils in agriculture, or as a growing medium generally. But this would only be conceivable if it's just carbon.
It extremely depends on the exact reactions. I'm not a chemist but AFAIK carbon nanotube production doesn't like taking in non-carbon atoms.
Things like crystallization reactions will produce very pure products, some other reactions will absorb more contaminants.
