Steam reforming - Wikipedia

Steam reforming or steam methane reforming is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is hydrogen production.The reaction is represented by this equilibrium: CH 4 + H 2 O ⇌ CO + 3 H 2. The reaction is strongly endothermic (consumes heat, ΔH r = 206 kJ/mol).
