Problems solved by technology

NaBH, which is more researched at present 4 System is an example, just there are following problems in the actual use process: 1) raw material cost is expensive; 2) palladium, ruthenium and other precious metal catalysts cost are high, and the service life of the catalyst is short after immobilization (because the hydrolysis reaction is the violent discharge that occurs on the surface of the catalyst. thermal reaction); 3) reaction product sodium metaborate (NaBO 2 ) is easy to block the pipeline; 4) the regeneration and recycling of the reaction by-products is difficult; 5) the stability of the hydrogen storage fuel solution is poor, because NaBH 4 In a metastable state in a strong alkaline aqueous solution, it is easy to spontaneously generate hydrolysis and release hydrogen, which has a very large safety hazard and is not conducive to long-term storage
These defects limit the wide application of this method

Embodiment 1

[0025] See attached figure 1 .

[0026] A hydrolysis hydrogen production device, which is composed of a storage tank 2, a reactor 4, a condenser 12 and a dryer 5, and is characterized in that the storage tank 2 stores solid reaction materials, and the storage tank 2 is connected with a driving mechanism 1, which drives Mechanism 1 communicates with hydrolysis reactor 4 . The storage tank 2 stores the solid reaction material as containing LiBH 4 , NaBH 4 and NH 3 BH 3 Capsules of three mixtures of 10. The driving mechanism 1 is fixed on the bracket 6, and the driving mechanism 1 is a cylinder piston, and a sealing O-ring 7 is installed at the front end of the push rod 8 of the cylinder piston. The driving mechanism pushes the solid reaction material capsule 10 into the hydrolysis reactor to produce hydrogen.

[0027] The upper part of the hydrolysis reactor 4 is located at the drive mechanism connected to the reactor inlet and is equipped with a solid reaction material c...

Embodiment 2

[0029] See attached figure 2 .

[0030] A hydrolysis hydrogen production device, which is composed of a storage tank 2, a reactor 4, a condenser 12 and a dryer 5, and is characterized in that the storage tank 2 stores solid reaction materials, and the storage tank 2 is connected with a driving mechanism 1, which drives Mechanism 1 communicates with hydrolysis reactor 4 . The storage tank 2 stores the solid reaction material as containing LiBH 4 , NaBH 4 and NH 3 BH 3 Three blends of 10 capsules.
