Nitrogen is a by-product of Oxygen. Oxygen is compressed and extracted at Air Bases for air-crews to breathe at high altitude.
Benefits of Dry Nitrogen include: No corrosion to wheels (oxidation is caused by oxygen), zero moisture means no condesation, and Nitrogen will not add oxygen to a fire, should the tire burn through.
Sorry but nitrogen and oxygen are both elemental gases. That means that one can't be made from the other. Nitrogen and oxygen are distilled from air through some rather complex expansion/compression operations. As others have noted both here and in other posts on this topic, nitrogen doesn't add any benefit in bicycling. Just expense.
