A methane reformer is a device based on steam reforming, autothermal reforming or partial oxidation and is a type of chemical synthesis which can produce pure hydrogen gas from methane using a catalyst. There are multiple types of reformers in development but the most common in industry are autothermal reforming (ATR) and steam methane ...
Partial oxidation (POX) is a type of chemical reaction. It occurs when a substoichiometric fuel-air mixture is partially combusted in a reformer, creating a hydrogen-rich syngas which can then be put to further use, for example in a fuel cell. A distinction is made between thermal partial oxidation (TPOX) and catalytic partial oxidation (CPOX).

These metal oxides have a high oxidizing tendency and can be used as oxygen carriers for the chemical looping combustion, gasification or partial oxidation processes. The metal oxides in Section E, the small section between the reaction lines 1 and 2, can be used for CLR and CLG, although a significant amount of H 2 O may present in the syngas ...
Steam methane reforming (SMR) produces hydrogen from natural gas, mostly methane (CH 4), and water. It is the cheapest source of industrial hydrogen, being the source of nearly 50% of the world's hydrogen. [34] The process consists of heating the gas to 700–1,100 °C (1,300–2,000 °F) in the presence of steam over a nickel catalyst.
Partial oxidation In chemistry, a partial oxidation (POX) reaction occurs when a substoichiometric fuel-air mixture is partially combusted in a reformer. Partial pressure In a mixture of ideal gases, each gas has a partial pressure which is the pressure which the gas would have if it alone occupied the volume.
Most methane is stranded, i.e. not located near metropolitan areas. Consequently, it is flared (converted to carbon dioxide). One challenge is that methanol is more easily oxidized than is methane. [3] Catalytic oxidation with oxygen or air is a major application of green chemistry. There are however many oxidations that cannot be achieved so ...
Syngas is produced by steam reforming or partial oxidation of natural gas or liquid hydrocarbons, or coal gasification. [6] C + H 2 O → CO + H 2 [1] CO + H 2 O → CO 2 + H 2 [1] C + CO 2 → 2CO [1] Steam reforming of methane is an endothermic reaction requiring 206 kJ/mol of methane: CH 4 + H 2 O → CO + 3 H 2
