New Technologies for Hydrogen Production from Natural Gas in Natural Gas Hydrogen Production Units
2020.12.29
SuZhou Jiarui Gas, a supplier of natural gas hydrogen production units, hereby introduces new technologies for hydrogen production from natural gas:
Adiabatic Reforming of Natural Gas for Hydrogen Production
The most prominent feature of this technology is that most raw material reactions are essentially partial oxidation reactions, and the rate-controlling step has become a fast partial oxidation reaction, which greatly improves the production capacity of natural gas hydrogen production units.
This process uses low-cost air as the oxygen source. The specially designed reactor with an oxygen distributor can solve the problem of hot spots in the catalyst bed and ensure reasonable energy distribution. The reaction stability of catalytic materials is also greatly improved due to the reduction of bed hot spots.
It better demonstrates its strong production capacity in small-scale on-site hydrogen production at hydrogen refueling stations. With the advantages of a short process flow and simple operation units, this new technology can significantly lower the investment of small-scale on-site hydrogen production facilities and the cost of hydrogen generation.
Partial Oxidation of Natural Gas for Hydrogen Production
Compared with traditional steam reforming, the catalytic partial oxidation of natural gas to syngas features lower energy consumption, and reactors can be built using extremely low-cost refractory materials.
However, catalytic partial oxidation of natural gas for hydrogen production requires large amounts of pure oxygen, leading to increased investment in expensive air separation units and oxygen production costs.
By using high-temperature inorganic ceramic oxygen-permeable membranes as reactors for catalytic partial oxidation of natural gas, low-cost oxygen production and hydrogen production via catalytic partial oxidation of natural gas are integrated and carried out simultaneously.
Preliminary techno-economic assessment shows that compared with conventional production processes, equipment investment can be reduced by about 25%–30% and production costs by 30%–50%.
High-Temperature Pyrolysis of Natural Gas for Hydrogen Production
High-temperature pyrolysis of natural gas catalytically decomposes natural gas into hydrogen and carbon at high temperatures. Since this process produces no carbon dioxide, it is regarded as a transitional technology connecting fossil fuel utilization and renewable energy applications.
Liaohe Oilfield has carried out extensive research on high-temperature catalytic pyrolysis of natural gas for hydrogen production. The carbon produced has special important applications and broad market prospects.
Autothermal Reforming of Natural Gas for Hydrogen Production
Compared with conventional reforming processes, this technology changes external heating to self-heating, achieving more rational utilization of reaction heat.
Its principle lies in the coupling of exothermic natural gas combustion and highly endothermic natural gas steam reforming reactions within the reactor, enabling the reaction system to achieve self-heating.
In addition, since the highly exothermic and highly endothermic reactions proceed separately in the autothermal reforming reactor, the reactor still requires high-temperature-resistant stainless steel tubes, resulting in disadvantages such as high equipment investment and low production capacity.
