Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is often hydrogen production , although syngas has multiple other uses such as production of ammonia or methanol .
As the steam reforming of methanol is more simple and efficient (catalyst bed temperature below 280°C) compared to reforming of other fuels and because of the low cost and high purity of conventional methanol and renewable methanol (e.g. made from waste or renewable power) as well as because of the simple storage of methanol, most HT-PEM fuel ...
The fuel cartridge stores the methanol fuel. Depending on the system design either 100% methanol (IMPCA industrial standard) or a mixture of methanol with up to 40 vol% water is usually used as fuel for the RMFC system. 100% methanol results in lower fuel consumption than water-methanol mixture (Premix) but goes along with higher fuel cell system complexity for condensing of cathode moisture.
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
Natural gas and other methane-rich gases, including those produced from municipal waste, are converted into syngas through methane reforming technologies such as steam methane reforming and auto-thermal reforming. Biomass gasification technologies are less established, though several systems being developed utilize fixed bed or fluidized bed ...
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 ...
The methanol economy is a suggested future economy in which ... The conventional route to methanol from methane passes through syngas generation by steam reforming ...
