Hydrogen
Hydrogen can be prepared in several different ways, but economically the most important processes involve removal of hydrogen from hydrocarbons. Commercial bulk hydrogen is usually produced by the steam reforming of natural gas. At high temperatures (1000-1400 K, 700-1100 degC or 1300-2000 degF), steam (water vapor) reacts with methane to yield carbon monoxide and H2.
