In plasma reforming the overall reforming reactions are the same as conventional reforming; however, energy and free
radicals used for the reforming reaction are provided by a plasma typically generated with electricity or heat .
When water or steamis injectedwith the fuel, H, OH, and O radicals in addition to electrons are formed, thus creating conditions for both reductive and oxidative reactions to occur .
Proponents maintain that plasma reforming overcomes many limitations of conventional techniques such as cost and deterioration of the catalysts, size and weight requirements, sluggish response, and limitations on hydrogen production from heavy hydrocarbons.
In addition, they can also be configured to operate at lower temperatures than traditional reforming .
In the cases where no catalysts are used to assist the reforming, the process is highly sulfur tolerant .
The main reported disadvantages include the electrical requirements and high electrode erosion at elevated pressures . Plasma reforming technologies have been developed to facilitate POX, ATR and steam reforming, with the majority of the reactors being POX and ATR .
There are essentially two main categories of plasma reforming: thermal and non-thermal .
