Autothermal Reforming

In autothermal reforming two different reactions are coupled: the exothermic reaction, represented by the fuel oxidation, and the endothermic reaction, represented by the steam­reforming.

Generally, the oxidation reaction, which is exothermic, releases much more energy than the steam-reforming reaction, which is endothermic, absorbs. This implies that less fuel is needed to be oxidized than reformatted.

The small amount of fuel which is oxidized generates heat to the fuel that will be reformatted. The temperature is similar to that of steam-reforming process.
