Technical Field
[0001] The utility model belongs to the technical field of metal cracking steam to produce hydrogen, and specifically relates to a system for producing hydrogen by directly cracking metal using steam. Background Art
[0002] Steam metal cracking hydrogen production technology is a "green" hydrogen production process with advantages such as free-energy hydrogen production, safety, efficiency, and low production costs. This technology generates hydrogen through the reaction of metals with water vapor. The device can produce hydrogen on-site, ready for immediate use, effectively reducing the costs and risks of hydrogen storage and transportation. This technology innovatively develops a new high-energy-density composite metal (zero-carbon) hydrogen-producing material that produces hydrogen through a series of reactions with water vapor. This material not only improves reactivity but also significantly reduces aluminum powder usage, lowering hydrogen production costs and making it commercially viable. Specific application scenarios include hydrogen blending and pure hydrogen combustion in boilers and oil and gas field heaters in the petroleum and petrochemical industries, green hydrogen production in the petroleum refining industry, hydrogen metallurgy, and integrated hydrogen production and refueling stations. This technology can effectively utilize surplus heat from oil and gas fields, wind power, photovoltaic power, solar thermal power, and other multi-energy sources for hydrogen production, as well as waste heat from refining plants, and is widely applicable in various hydrogen-intensive applications.
