The mainstream hydrogen production mode in the current market is to obtain hydrogen by reforming natural gas, coal, gasoline and diesel oil or cracking methanol, on one hand, the storage capacity of the raw material is limited and the raw material cannot be regenerated; on the other hand, the reaction process is complicated and a large amount of greenhouse gases are emitted. The hydrogen production by electrolyzing water and photolyzing water is also a hot spot of research of people at present, but the energy efficiency needs to be further improved.
Aluminum, which is the most abundant metal element in the earth's crust, can generate hydrogen through hydrolysis, and has an energy density as high as 29MJ/kg, thus being an environmentally friendly energy carrier. However, when the aluminum is exposed to air, a dense oxide film is formed on the surface, thereby preventing the aluminum water reaction from further proceeding.
Researches find that the gallium-based liquid metal can destroy an oxide film of aluminum at room temperature, and diffuses into the aluminum along the aluminum crystal boundary to enhance the reaction activity of the aluminum, thereby realizing the timely and rapid hydrogen production. The pulse tube utilizes the alternating pressure wave to form axial temperature gradient in the tube, generates a large amount of compression heat in the hot end heat exchanger, has no moving parts in the whole system, and has wide application prospect in various industries.
The pulse tube and hydrogen production are combined, the energy utilization rate is improved, the pulse tube heat and hydrogen co-production system and the pulse tube heat and hydrogen co-production method which are environment-friendly and free of carbon emission and based on aluminum water reaction are developed and utilized, the high-efficiency utilization of clean energy is realized, and the pulse tube heat and hydrogen co-production system and the pulse tube heat and hydrogen co-production method have very important theoretical and practical significance and are key technical problems which are urgently needed.
