![]() The above reaction is highly endothermic it consumes energy from the surrounding. ![]() The reaction that is taking place in this reformer is as follows: Syngas is a mixture of hydrogen gas and carbon dioxide gas. The purpose of this reforming reaction is the production of pure hydrogen gas. In this technique, the most common feedstock is natural gas. Steam reforming is the technique of producing syngas through the reaction of hydrocarbons with water. Side by Side Comparison – Steam Reforming vs Autothermal Reforming in Tabular Form There are many different reformers in industries, and autothermal reformer and steam methane reformer are the most common ones. This device uses two main reactions: steam reforming, autothermal reforming or partial oxidation. Reformers are devices useful in chemical synthesis of pure hydrogen gas from methane in the presence of a catalyst. The key difference between steam reforming and autothermal reforming is that steam reforming uses the reaction of hydrocarbons with water, whereas autothermal reforming uses the reaction of methane with oxygen and carbon dioxide or steam to form syngas.
