Partial Oxidation

A sub-stoichiometric quantity of oxygen, or air, is used in the partial oxidation fuel reaction. This small amount of oxidant produces some heat and water that reacts with the non-oxidized fuel to generate hydrogen and carbon dioxide, considering theoretical approach showed in Eq. (3).

However, practical systems, based on partial oxidation technology, generate syn­gas with less hydrogen than other methods such as autothermal or steam-reforming. A large amount of carbon monoxide is yielded. The process temperature is also higher, around 1000°C.
