Currently, hydrogen is mainly produced from natural gas by three different chemical processes: steam reforming, partial oxidation, and autothermal reforming [1], [2], [3], [4], [5], [6] and [7]. Steam reforming involves the endothermic conversion of methane and water vapor into hydrogen and carbon monoxide. The high temperature requirement (700 to 1000 °C) is often achieved by the combustion of some of the methane feed gas. Partial oxidation of natural gas, on the other hand, is the process whereby partial combustion of methane with oxygen gas yields carbon monoxide and hydrogen. Heat is produced in an exothermic reaction; therefore, a more compact design is possible because external heating of the reactor is not required. Finally, autothermal reforming is a combination of both steam reforming and partial oxidation. The total reaction is exothermic; hence, heat is released. The outlet temperature of the reactor is in the range of 600 to 900 °C [3].
