Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production, in particular to a hydrogen purification device. Background Art

[0002] Production of hydrogen from natural gas is currently one of the simplest, most efficient and least costly methods. Under a certain pressure, high temperature and catalyst action, alkanes and water vapor in natural gas undergo a chemical reaction, and the converted gas undergoes heat exchange in a boiler and enters a conversion furnace, where it is finally converted into hydrogen and carbon dioxide.
