Description

TECHNICAL FIELD

[0001] The utility model relates to hydrogen production equipment technical field, especially a small -size hydrogen production purification device. BACKGROUND

[0002] Hydrogen production is a process of converting different raw materials into hydrogen. The main methods include pyrolysis, electrolysis of water, photochemical decomposition of water and biological method. Pyrolysis decomposes hydrogen by heating water-containing substances (such as fossil fuels, biomass), but produces a large amount of pollutants. Electrolysis of water uses electrolytic cell to decompose water, which has high energy consumption but high hydrogen purity. Photochemical decomposition of water uses photocatalyst to decompose water, which does not produce pollutants but requires expensive equipment. Biological method uses microorganisms to combine carbon and hydrogen in water into hydrogen under specific environmental conditions, which has the characteristics of low energy consumption and renewable, but requires suitable environmental conditions. In the process of hydrogen production, attention should be paid to the selection of raw materials, reactor type, reaction conditions and catalyst dosage to ensure safety and optimal hydrogen production effect.
