Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0033] figure 1 A specific embodiment of a hydrogen storage and discharge method and system based on a magnesium-based hydrogen storage material according to the present invention is shown.
[0034] As can be seen from the figure, magnesium chloride forms liquid magnesium chloride through melting in the melter 1; liquid magnesium chloride flows into the electrolytic cell 2, and obtains liquid metal magnesium and chlorine through electrolysis; liquid metal magnesium flows into the magnesium hydride preparation device 3, and passes through successively Argon atomization and hydrogenation to obtain magnesium hydride; chlorine gas is collected by the hydrogen chloride reactor 6 and hydrogen is generated under the action of a catalyst to generate hydrogen chloride; magnesium hydride is decomposed by heating or hydrolyzed in the hydrogen generator 4 ...

The invention discloses a hydrogen storage and release method and a hydrogen storage and release system based on a magnesium-based hydrogen storage material. The method comprises the following steps:(1) carrying out melting electrolysis on magnesium chloride to generate liquid metal magnesium and chlorine; (2) carrying out gas atomization on the liquid metal magnesium to form magnesium metal powder; and (3) carrying out a hydrogenation reaction on the magnesium metal powder to generate magnesium hydride. The system comprises a melter, an electrolytic cell and a magnesium hydride preparation device, wherein the melter is arranged to be capable of melting magnesium chloride, the electrolytic cell is arranged to electrolyze molten magnesium chloride into liquid magnesium metal and chlorine,and the magnesium hydride preparation device is arranged to atomize the liquid magnesium metal through argon to form magnesium metal powder and react the magnesium metal powder and hydrogen to generate magnesium hydride.
Description
technical field [0001] The invention relates to the field of hydrogen storage and discharge, in particular to a hydrogen storage and discharge method and system based on magnesium-based hydrogen storage materials. Background technique [0002] As a renewable and clean secondary energy source, hydrogen has many advantages. Hydrogen energy is efficient, pollution-free and renewable, so it is imperative to develop new energy represented by hydrogen energy. However, the hydrogen fuel system in vehicles at this stage usually has problems such as difficulty in storing and discharging hydrogen, poor safety, and low hydrogen storage density. In addition, the transportation of hydrogen consumes a lot of energy, and the cost of compressing hydrogen or liquefied hydrogen is high, resulting in waste of resources. Therefore, it is difficult to achieve large-scale commercial application. Compared with high-pressure hydrogen cylinders and low-temperature liquid hydrogen, solid-state hydr...
